Statement of Work EB Voltage Regulator Board Replacement

BACKGROUND

Reclamation requires that the voltage regulators on all (3) generator units 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 The main processor chip on the Basler ECS-2100 is obsolete and cannot be repaired, replaced nor is it supported anymore and is a known point of failure.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.

SCOPE

Retrofit the current Basler ECS-2100 voltage regulators with current Basler DECS-2100 voltage regulators. Vendor shall include all labor, parts, equipment to install, commission, and train personnel on the three generating units at Elephant Butte Field Division.

REQUIREMENT

Digital front end retrofit the current Basler ECS-2100 voltage regulators to DECS-2100 voltage regulator on generator units 1, 2, 3 with installation, commissioning, and training. This requirement must meet the following criteria:

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 see attached drawings. Drawings show unit 1 but dimensions are typical for all three units.

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

7. Removal of the existing ECS2100 control equipment and Installation of the new Basler Electric DECS-2100 Front-End Retrofit.

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

9. 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 9a – 9f), supplied in AutoCAD (dwg format).

· c. Startup Report, including all Software Settings.

10. 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.

11. 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

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

13. 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

· AVR “Automatic Voltage Regulator” Start Sequence

· FCR “Field Current Regulator” Start Sequence

· AVR Step Response Testing & FCR Step Response Test

· Off-Line OEL Overexcitation Limiter Stability Step Test

· Saturation Curve Testing

c. On-Line System Tests

· AVR Step Response Test & FCR Step Response Test

· On-Line OEL Overexcitation Limiter Stability Step Test

· UEL Under-excitation Limiter Settings & Stability Step Test

14. In addition to the retrofit also include the replacement of the following devices, one for each unit (3 total each):

a. BCM-2, 2nd Generation Bridge Control Module

b. FGD-2, 2nd Generation Field Ground Detector Module

c. DXCB-2, 2nd Generation De-Excitation & Crowbar Module

d. AIOM-2, 2nd Generation Analog I/O Module

15. Include backups to all programs to include changes made during commissioning. Prior to leaving work site at project completion.
