General Information

The Bureau of Reclamation, Parker Dam and Power Plant is located at 2001 Parker Dam

Rd. Parker CA, 92267 in San Bernardino County California, Latitude: N 34° 17' 41.3844"

Longitude: W 114° 8' 24.9684".

Background

The Bureau of Reclamation (BOR) Parker Dam has 4- 30MW Francis style turbine hydrogenators equipped with Eaton/ Basler static excitation cabinets. These excitation cabinets were installed between 2005 and 2011 and require the voltage regulators on all (4) generator units to be refurbished. The current voltage regulators are Basler ECS-2100. The main processor chip on the Basler ECS-2100 is obsolete and cannot be repaired, replaced nor is it supported anymore and is a known point of failure. Reclamation is looking to replace the Basler ECS-2100 with the current Basler Regulator DECS-2100 as well as the other associated components included in the BASLER DECS-2100 digital exciter controller upgrade.

Scope of Work

Overview- Provide the retrofit of the current Basler ECS-2100 voltage regulators with current Basler DECS-2100 voltage regulators conversion kit. Vendor shall provide a turnkey installation to include all labor, parts, equipment to install, commission, and train personnel on the four 30MW hydrogenating units at Parker Dam.

Requirements

Digital front end retrofit the current Basler ECS-2100 voltage regulators to DECS-2100 voltage regulator on generator units P-1, P-2, P-3, P-4 with installation, commissioning, and training. Also provide a complete spare 5th set of all hardware components

(programmed) and cables associated with DECS-2100 Front-End Upgrade Kit programmed for future and a minimum of 1 spare Magnum DS MDS816 Exciter Breaker.

1. Provide the current version of Basler BESTCOMS™ Pro Controller configuration tool

2. Auto tuning of control loops

3. Must use existing rectifier bridge.

4. Plug and play replacement.

a. Compatible with existing analog to digital I/O boards

5. All equipment must fit within existing equipment footprint for all four units.

6. Research of the existing Generator Control System to finalize Installation Details.

7. The existing ECS2100 controller utilizes a throughput sampling rate of 1kHz (the code reads inputs, executes excitation system and power system stabilizer code and updates the outputs ever 1 millisecond). Any replacement controller must meet or exceed this performance requirement.

8. Removal of the existing ECS2100 control equipment and Installation of the new

Basler Electric DECS-2100 Front-End Retrofit.

9. Supply any additional cabinet wiring, which may be needed, with regard to the installation of the new Basler Electric Exciter System.

10. Provide the “Interface Design” of the new Systems including:

a. Provide all revisions to the existing Elementary System Drawing Package of the Generator Control and Voltage Regulator Systems.

b. Connection details for all new devices as supplied by contractor to be installed in the new Regulator Control Panel.

c. System Connection Drawings.

d. Wiring Lists of wires to be removed, wires to be reused and new wire to be added.

e. Interface details for direct connection of the new excitation equipment to the existing Control System and details on existing equipment to be removed from service.

f. Voltage Regulator Control System Settings.

g. Digital Documentation Package to include.

▪ a. Instruction Manuals for all equipment of the new Basler Electric

Systems.

▪ b. As Built Digital Drawings (per above in items 10a – 10f), supplied in AutoCAD (dwg format).

▪ c. Startup Report, including all Software Settings.

11. Provide On-Site Turnkey Services by Basler factory trained Technical Expert with regard to the Installation, Connection and Interconnection of the new Basler

Electric Systems.

a. Remove the ECS2100 equipment.

b. Install the new DECS-2100 Front-End retrofit in the existing exciter cabinet.

c. Interface with the existing Generator Control, Protection and Annunciator

Systems.

d. Provide System Checkout / Testing of all new equipment, devices and interconnection cables.

12. Provide System Startup Services

a. Shut-down (Unit at standstill) checks with external equipment – DCS, Remote Switches, etc.)

b. Off-Line (Rated Speed No-Load) Set-Up and Testing of the new Voltage

Regulator Control System.

c. On-Line (With Load) Set-Up and Testing of the new Voltage Regulator

Control System

13. Provide the “final” System Startup Report with regard to the commissioning of the new Basler Electric Type DECS-2100 System.

14. On-Site Commissioning Tests

a. Pre-Excitation System Checks (Unit @ Standstill)

▪ Wire Checks / Ground Checks of the new System

▪ Control I/O Testing & Sequence Testing

▪ Loss of PT Signal Transfer Testing

▪ Excitation Simulation Checks (Dummy Load Test)

▪ Current & Voltage Signal Injection

▪ Unit Annunciation Alarm Checks

▪ DCS Interface Checks

▪ System “Trip” Tests

▪ DECS Module Software Setup

b. Off-Line, Full Speed No-Load System Checks
