In each Barrier facility of IIA and IIB there are a total of (3) three PGUs each with the control systems and supportive control systems mentioned in the previous paragraph; there are (2) two 1.5MW PGUs (commonly known as Pulser 1 and Pulser 2) and (1) one 350KW PGU (commonly known as Pulser 3). Therefore, for clarity each Barrier IIA and IIB have 3 PGUs as mentioned previously for a total of (6) PGUs. The Contractor shall remove all existing PGCS controls components and equipment with the exception of the items that will be reused as detailed in the plans (One Line Diagrams). Any removed components and equipment shall be disposed of per the contracting officer. The requirements in this section and associated subsections apply to Barrier IIA. Should Option Work, Supply Pulse Generating Unit Controls Barrier IIB be awarded, the requirements of this section also apply to Barrier IIB.

The PGCS shall be installed per this Performance Work Statement (PWS) and Plans. These provided Government documents detail the majority of work. However, there may be some work that requires additional details and the Contractor is responsible to obtain these additional details and implement in the installation of the PGCS. Because this is a PWS, the Contractor shall determine what is needed. The Contractor is required to perform a site survey. See the requirements for “Technical Data Package 2” for additional details. There are items that the Contractor will need to determine such as the IGBT controls.

Currently, the existing Barrier Facilities converts 480 Volts (V) alternating current (AC) power into a pulsed DC power as described below where the existing PGCS is able to operate the PGUs at an adjustable range within the prescribed parameters for Volts, pulse frequency, and pulse duration allowed by the equipment. The existing PGCS equipment capabilities provides the PGUs with pulsed voltages of any value from 0- 2,000V and 0-1000V and peak pulse currents up to 7,500 Amps (A) and 3,000 Amps (A) for the 1.5MW and 350KW PGUs output respectively with a pulse frequency up to 100 Hertz (Hz) within increment adjustments of 0.5Hz and a pulse duration of 0-100,000 microseconds (µs) (100 milliseconds (msec)) within increment adjustments of 150 microseconds (µs) (0.15 milliseconds (msec). The new PGCS shall also provide these capabilities; more detail for this control is provided further in this PWS and Appendix A, B, C, D, E and F.

The Contractor shall provide a PGCS that includes control stations for the PGUs at BarriersBarrier IIA facility (and Barrier IIB facilitiesfacility if the option is exercised) respectively as well as a control station that allows for control of each Barrier IIA &PGU (and Barrier IIB PGU if the option is exercised) in the PB1 facility; more detail for this control is provided further in this PWS and Appendix A, B, C, D, E and F. The Contractor shall provide a PGCS that allows each Barrier IIA PGU (and Barrier IIB PGU if the option is exercised) to be capable of being synchronized or interleaved with all other PGUs at PB1 and Demonstration Barrier facilities. Consistent with the synchronization system currently being used at the barriers, each PGU shall use the leading edge of a pulse from a Global Positioning System (GPS) signal with a given offset based on a percentage of the operating frequency to achieve synchronization or interleaving with other PGUs on site to include the PGUs in Barriers IIA and IIB, the PB1 barrier facility and the Demonstration Barrier. More detail for this control is provided further in this PWS and AppendicesAppendix A, B, C, D, E and F.

The Contractor shall coordinate with other contractors thatwho may be working at Barrier IIA, IIB, PB1 and Demonstration Barrier facilities. The Contractor shall work within the existing site conditions, including the structural building and support systems built under separate contracts. If this is not possible the contractor shall include any and all alterations in the initial proposal.

Existing Infrastructure to Support Barrier IIA and IIB PGCS

The following components of the Barrier IIA (and Barrier IIB if the option is exercised) are existing and to be integrated into the new PGCS with backup generator remote control, including: PGU equipment to include but not limited to the IGBT assemblies, the high voltage power supplies, capacitive storage banks; the cooling system equipment for the PGUs; the underwater electrodes and the cabling from the electrodes to the ground surface; the building with its supporting electrical (other than PGCS equipment); the mechanical systems HVAC for Barrier IIB only; (if the option is exercised); the facilities backup generators; and the corresponding control systems for the aforementioned components.

The Contractor shall utilize the existing infrastructure (cooling system, electrical, and physical building layout) for the PGCS, associated systems and remote backup generator control. If the existing infrastructure is insufficient, it is the contractor’s responsibility to include any alterations and costs of those alterations in the proposal prior to bidding. As a PWS with a design concept, additional design is required as part of the PWS. The objective of this PWS includes completing the design based on the existing conditions. The requirements of this section apply to Barrier IIA. Should Option Work, Supply Pulse Generating Unit Controls Barrier IIB be awarded, the requirements of this section also apply to Barrier IIB.

The Barrier IIA and IIB facilities details to include dimensions and other details, are set forth in Appendix B Drawings.

Similarly for Barrier IIA and IIB the 1.5MW PGU’s (commonly known as Pulser 1 and Pulser 2) major equipment include but are not limited to: a 3.4KV, 30KA ABB/Astrol IGBT assembly; a 1.5MW 480VAC to 3.2KVDC High Voltage Polarity/Position Switches (HVPS); and a 0.1135 Farad (F) capacitor bank comprised of fifty (50) each 3300V, 2270 microfarad capacitors. The 350kW PGU’s (commonly known as Pulser 3) major equipment include but are not limited to: a 2.0KV, 10KA ABB/Astrol IGBT assembly; a 350kW 480VAC to 2.0KVDC HVPS; and a 0.05675 (F) capacitor bank comprised of twenty-five (25) each 3300V, 2270 microfarad capacitors. More detail for this control is provided further in this PWS and Appendix A, B, C, D, E and F.

Barrier IIA has two (2) each 25KV, 6.5KA, 3 Position HVPPSs. One HVPPS allows switching between Pulser 1 and Pulser 2 while the other allows switching between Pulser 2 and Pulser 3; effectively making Pulser 2 the backup for either Pulser 1 or Pulser 3. Originally all HVPPs were 6 position. Later the IIA HVPPs were modified to 3 position. The number of positions shall be confirmed by the Contractor. The switches 3 positions will include an off position and switching between PGUs as detailed in previous sentence. The HVPPS has an auto lube system, and electrical motor to change positions and control feedback for HVPPS position. Barrier IIB has two (2) each 25KV, 6.5KA, 6 Position HVPPSs. One HVPPS allows switching between Pulser 1 and Pulser 2 while the other allows switching between Pulser 2 and Pulser 3; effectively making Pulser 2 the backup for either Pulser 1 or Pulser 3. The 6 positions will include an off position and switching between PGUs as detailed in previous sentence and allow for polarity switching of all PGUs. The HVPPS has an auto lube system, and electrical motor to change positions and control feedback for HVPPS position.

Barrier IIB similarly to Barrier IIA has two (2) each HVPPSs with the same specifications as IIA. However, Barrier IIB uses all 6 positions of the HVPPS. More detail for this control is provided further in this PWS and the Appendix A, B, C, D, E and F.

Barrier IIA and IIB both utilize two (2) each closed loop liquid cooling systems for the PGUs. Each consists of a deionized (DI) water system for the IGBT assemblies and a water/glycol system for the HVPSs. There are multiple sensors to include but not limited to flow, temperature, conductivity and pressure for each system as well as circulation pumps, piping and valves; it is expected for this equipment to be reused in the new PGCS. More detail for this control is provided further in this PWS and the Appendix A, B, C, D, E and F.

There are two (2) underwater electrode (steel bar assemblies) arrays per Barrier IIA and Barrier IIB; there is a “narrow” array and a “wide” array. They are referred to as narrow and wide due to the orientation of the underwater electrodes. The narrow array has electrodes that are spaced closer together while the wide array has electrodes that are spaced further apart. Further details are set forth in Appendix D. The narrow array consist of twenty-four (24) each - 5”x5” electrodes approximately 156’ long while the wide array consist of eighteen (18) each – 5”x5” electrodes approximately 156’ long with each electrode spanning the width of the canal and resting on underwater concrete sleepers. The narrow array has two major groupings with twelve (12) each electrodes per major grouping while the wide array has nine (9) each electrodes per major grouping. The two groupings for each array will provide each array with a cathode and an anode. Each electrode has one 250kcmil, 5KV, High Density Polyethylene (HDPE) cable (known as the electrode cables) attached to each end (see additional details in Appendix F). Therefore, there are a total of forty- eight (48) each cables for narrow array and 36 cables for the wide array. The electrode cables are routed through several conduits that feed from the underwater electrodes through the CSSC embankment up to the bus bar raceway and the electrode cables are attached to the bus bar. The bus bar is routed through the raceway where it is attached to a HVPPS, thereby each array is fed by one of the two HVPPSs. The two (2) each underwater electrode arrays will generate an independent pulsed direct current (DC) electric field in the CSSC powered by the PGUs.

Barrier IIA has one (1) 3MW emergency generator sized with the capability of running both the narrow and wide array for the IIA facility. Power to the IIA barrier is routed through a Power Quality Improvement (PQI) building housing a 2MW USP, harmonic filters and automatic switch gear. The PQI building has a power monitoring system fed to the IIA building,. It also has a temperature monitor which alarms in the IIA building if the interior exceeds 90 degrees F. The new Barrier IIA system shall provide similar monitoring capacities. More detail for this control is provided further in this PWS and Appendix A and B.

Barrier IIB has two (2) each 2MW emergency generators that have the capability of running both the narrow and wide array for the IIB facility simultaneously. However, this is accomplished by applying a power limit to each PGU with the existing PGCS. The If the option is exercised, the new Barrier IIB PGCS shall provide the same functionality; more detail for this control is provided further in this PWS and the Appendix A and B.

In addition, the control for the existing emergency generators is currently located locally at the Barrier IIA and IIB facilities. The Contractor shall integrate the existing emergency generator controls at Barrier IIA (and IIBBarrier IIB if the option is exercised) with the existing controls in the PB1 facility to allow for control and monitoring of the existing Barrier IIA (and IIBBarrier IIB if the option is exercised) emergency generators in the PB1 facility. More detail for this control is provided further in this PWS and the Appendix A and B.

No additional equipment will be furnished as Government Furnished Equipment (GFE) unless otherwise directed by the Government. The contractor shall provide all equipment required to have a complete and functional Pulse Generating Control System at Barrier IIA (and Barrier IIB if the option is exercised) with remote control capability of existing emergency generators at BarriersBarrier IIA (and Barrier IIB if the option is exercised) from PB1 facility. The Contractor’s proposal shall not include or assume the Government will furnish any additional equipment not already installed at the project site.

Existing Fish Dispersal Barriers.

Barrier IIA is located in the CSSC approximately 1,150 feet downstream of the Demonstration Barrier which is located at river mile 296.5. Barrier IIA utilizes three Pulse Generating Units each comprised of a rectifier, capacitor bank, and IGBT pulsed power assembly to generate a pulsed DC in the water. Barrier IIA has forty-two (42) each electrodes that span over one hundred thirty (130) feet upstream-to-downstream on the canal bottom.

Barrier IIA has two (2) sub-parts known as the wide and narrow arrays. The narrow array extends over approximately fifty (50) feet upstream-to-downstream in the canal and is where the maximum electric field strength of the barrier can be generated. The operating parameters for the narrow array are normally a DC voltage in the water with a maximum field strength at the water surface of 2.3 volts/inch from a source of a DC voltage of 2,000V, at 8,000A peak pulse current, a frequency of 34 Hz with a pulse duration of 2.3 milliseconds (msec). However, these operating parameters can be adjusted. The wide array extends over approximately eighty (80) feet upstream-to-downstream, but can’t generate field strengths as high as the narrow array. The operating parameters for the wide array are normally a DC voltage in the water with a approximate field strength at the water surface of one (1) volt/inch from a source of a DC voltage of at 800VDC, at 2000A peak pulse current, a frequency of 34 Hz with a pulse duration of 2.3milliseconds (msec). The wide array is downstream of the narrow array. Barrier IIA was placed into full time operation in 2009.

The barriers are presently programmed to pulse at a constant pulse repetition frequency and an equal spacing of pulses between IIA and IIB. Additionally, when the power threshold is reached during times of high water conductivity, the barriers are programmed to reduce the voltage while maintaining a constant pulse width and frequency to stay within the power capabilities of the barriers, which is 1.5 MW for Barrier IIA and 1.5 MW for Barrier IIB.

Barrier IIB is located in the CSSC, approximately eight hundred (800) feet downstream of the Demonstration Barrier and two hundred-twenty (220) feet upstream of Barrier IIA. Barrier IIB utilizes equipment with very similar specifications and quantity to the equipment in Barrier IIA. It has the same type, number, and spacing of electrodes as Barrier IIA, and similar operating parameters. Barrier IIB was placed into service in April 2011.

The Demonstration Barrier is located in the CSSC at approximately river mile 296.5. It consists of twelve 5”x5” steel electrodes secured just above the canal bottom. The upstream-to-downstream length of the barrier is 54 feet. A rapidly pulsed DC current is sent through the cables creating an electric field in the water that extends to the water surface. The Demonstration Barrier utilizes 4 Pulse Generating Units each comprised of a rectifier, capacitor bank, and an Insulated Gate Bipolar Transistor (IGBT) pulsed power assembly to generate pulsed DC voltage in the water with a maximum field strength at the water surface of 1 volt/inch, a frequency of 5Hz with a pulse duration of 4mS. There are two 125KVA and two 25KVA Pulse Generating Units. The Demonstration Barrier has been operational since 2002.

The Permanent Barrier I (PBI) facility is located between Barrier IIB and the Demonstration Barrier. The Permanent Barrier I facility building construction is complete. However, the construction of one of the two

(2) each 4.3MW pulse generating units is currently underway and is expected to be complete in late fall of 2020.

These PGCSs The PGCS will be installed within twothe separate IIA barrier facilities IIA facility (and (optional)the separate IIB barrier facility if the option is exercised) independently of each other and allow for local control in each facility as well as remote control from the PB1 facility.

For purposes of information only, the Government has observed ambient water conductivity canal conditions between six hundred (600) micro-Siemens per cubic centimeter (µS/cm) (ambient) at 86˚F for summer months and twenty eight hundred (2800) µS/cm (ambient) at 34˚F in winter (additional historical data can be made available after contract award). For purposes of information only, the Government has observed at the existing barriers that the peak current increases by approximately 1,500A when a metal hulled vessel passes through the barriers (additional detailed data can be made available after contract award).

Pulse Generating Control System Operation The Pulse Generating Control System Operation for Barrier IIA (and for Barrier IIB if the option is exercised) shall include, but is not limited to, the following operations for the purpose of generating the required DC electrical pulses through the underwater electrodes. The Contractor shall evaluate existing equipment capacity and match or exceed the minimum capacity. The PGCSThe PGCS for Barrier IIA (and for Barrier IIB if the option is exercised) shall provide operation per this PWS and at a minimum replace the existing operation of the equipment and control at BarriersBarrier IIA (and Barrier IIB: if the option is exercised):

(a) The PGCS at Barrier IIA and Barrier IIB currently operates with parameters for the 1.5MW PGU of 2,000V with a pulse duration of 2.3 msec at 34Hz and for the 350kW PGU parameters of 800V with a pulse duration of 2.3 msec at 34Hz.

(c) The Contractor shall provide and install IGBT Assembly control for the existing IGBT assembly, existing IGBT assembly supportive devices and new IGBT assembly devices. for Barrier IIA (and for Barrier IIB if the option is exercised).

a. The PGCS shall monitor the operation of the IGBT assembly and subsequently will alter the PGCS control with minimal operation as currently in place and as required. for Barrier IIA (and for Barrier IIB if the option is exercised).

b. The existing 1.5MW PGU IGBT assembly is rated 3.4kV/30kA and capable of being operated at peak output rectangular currents of the following: 6,500A peak at 100% duty cycle, 10,000A peak at 40% duty cycle, 20,000A peak at 10% duty cycle, and 30,000A peak at 4% duty cycle; however due to limitations of other PGU equipment the current is thought to be limited to approximately 2000A RMS current with peak pulse currents approximately 7200A and the peak pulse current shall never be greater than 30kA with resulting shutdown of equipment and alarms. The existing 350kW PGU IGBT assembly is rated 2kV/10kA and capable of being operated at peak output rectangular currents of the following: 2,700A peak at 100% duty cycle, 4,300A peak at 40% duty cycle, 8,400A peak at 10% duty cycle, and 10,000A peak at 8% duty cycle; however due to limitations of other existing PGU equipment the current is thought to be limited to approximately 600A RMS current with peak pulse currents approximately 2145A and the peak pulse current shall never be greater than 10kA with resulting shutdown of equipment and alarms.

c. Currently, the IGBT assembly is controlled with an IGBT controller on board the assembly and communicates with the existing PGCS with fiber optic serial protocol. The IGBT assembly controller provides signals to the onboardon board gate drivers to “switch” the IGBT modules and in addition provides diagnostic monitoring to trigger alarms and failures. There are a total of (4) four each fiber optic communication lines; three (3) each output signals to the PGCS and one (1) each input signal from the PGCS to the IGBT controller. The three (3) each output signals include the following; one (1) each feedback signal-switching status on/off-(EXT_TRIGG_FP), one (1) each status signal- short circuit status-(STATUS_1), and one (1) each status signal-gate drive unit failure status-(STATUS_2). The input signal-(TRIGG_IN-IP)-on/off (pulse generator) is provided via the existing function generator; this signal is a pulse train of light supplied to the IGBT controller that will provide the pulse duration (pulse width) and pulse frequency. The pulse train is currently provided by the existing “Keysight” oscilloscope for each PGU in Barrier IIA and “Bitscope” in Barrier IIB and can. The “Keysight” oscilloscopes may be reused in IIA and, and if the option for Barrier IIB is exercised new oscilloscopes equal to the “Keysight” oscilloscope shall be provided for each PGU in Barrier IIB. More information can be provided regarding the IGBT controller after award of the contract.
