About this file

Written by GovTribe AI · Dec 27, 2023

This is an amendment to a solicitation for the replacement of primary medium voltage switchgear at the Doris Miller VA Medical Center in Waco, Texas. The Department of Veterans Affairs is seeking to replace aging switchgear equipment through a competitive procurement process. Offerors must submit proposals by a specified due date to be considered for award of a firm fixed price contract to furnish all labor, materials, tools, and equipment for the demolition and installation of a new medium voltage electrical distribution system. The selected contractor will be responsible for coordination with the local utility, permitting, and execution of a detailed transition plan to migrate existing electrical feeds to the new switchgear while maintaining continuous power to critical VA facilities.

SEQUENCE OF OPERATION

GENERAL

1. THE ACCOMPANYING DIAGRAM IS A REDUCED ONE-LINE DIAGRAM TO BE USED TO ILLUSTRATE PROTECTIVE RELAYING OPERATION ONLY.

SEE SHEETS E5.1, E5.2 & E5.3 FOR MORE COMPLETE SYSTEM ONE-LINES.

NORMAL OPERATION

1. NORMAL OPERATION OF SYSTEM IS CONSIDERED TO BE COGEN UNIT OPERATING PARALLEL WITH THE UTILITY. A HOT UTILITY SOURCE.

LOSS OF UTILITY

1. PROTECTIVE RELAYS 'INC1' AND 'INC2' SHALL BE USED TO SENSE LOSS OF THE UTILITY SUPPLY TO THE CAMPUS OR OTHER ABNORMAL

CONDITIONS AS DESCRIBED BELOW.

2. RELAY FUNCTIONS TO BE PROVIDED INCLUDE THE FOLLOWING. NUMBERS IN PARENTHESES REFER TO ANSI/IEEE DEVICE NUMBERS.

UNDER-VOLTAGE (27) W/ TWO STEPS OF PICKUP *

OVER-VOLTAGE (59) W/ TWO STEPS OF PICKUP *

UNDER-FREQUENCY (81U)

OVER-FREQUENCY (81O)

REVERSE POWER (32) *

DIRECTIONAL GROUND OVERCURRENT (67N)

* INDICATES PER PHASE SENSING IS REQUIRED

3. ALL SETTINGS SHALL CONFORM TO THE PARALLELED INTERCONNECTION REQUIREMENTS OF ONCOR ELECTRIC, THE SERVING UTILITY COMPANY. CONTRACTOR SHALL PROVIDE PLACARDS AT THE ONCOR METERING LOCATION TO MEET THE CLASS 3 REQUIREMENTS

DESCRIBED IN THEIR DOCUMENT TITLED “ONCOR PLACARD GUIDELINE.”

4. EXISTING BREAKERS 'UTIL1' & 'UTIL2' ARE ELECTRICALLY INTERLOCKED TO PRECLUDE THEIR SIMULTANEOUS CLOSING. AUXILIARY BREAKER POSITION CONTACTS IN BREAKERS 'UTIL1' & 'UTIL2' SHALL BE USED TO DETERMINE WHICH OF THE TWO INCOMING UTILITY SOURCES IS CURRENTLY FEEDING THE CAMPUS AND BEING OPERATED IN PARALLEL WITH THE COGEN UNIT. TRIP SIGNALS TO THE COGEN FEEDER BREAKERS ('CG1' & 'CG2') SHALL ORIGINATE FROM THE RELAY ('INC1' OR 'INC2') CORRESPONDING TO THE CURRENTLY ACTIVE FEED.

5. UPON DETECTION OF MANDATORY TRIP CONDITIONS PER ITEM 3 ABOVE THE FOLLOWING SHALL OCCUR. A TRIP SIGNAL FROM THE

ACTIVE UTILITY SUPPLY RELAY ('INC1' OR 'INC2') SHALL BE SENT TO BREAKER 'CG1'.

6. POSITION SWITCHES IN SHALL BE PROVIDED IN BREAKER 'CG1' TO MONITOR FOR A SUCCESSFUL TRIP. IF AFTER THE EXPIRATION OF A ONE SECOND DELAY A TRIP OF BREAKER 'CG1' HAS NOT BEEN SENSED BY THE INCOMING SOURCE RELAY, A BACKUP TRIP SIGNAL SHALL BE

SENT TO BREAKER 'CG2'.

7. ALL NEW DEVICES SHALL BE FIELD TESTED AND CALIBRATED. AFTER CALIBRATION AND TESTING THE CONTRACTOR SHALL FULLY COMMISSION THE SYSTEM TO VERIFY CORRECT OPERATION OF EACH OF THE ITEMS ABOVE. TESTING SHALL INCLUDE TESTING BY SECONDARY INJECTION TO SIMULATE EACH OF THE ABOVE CONDITIONS. THE ENGINEER WILL WITNESS THE TESTING AND COMMISSIONING. CONTRACTOR SHALL PROVIDE DETAILED WRITTEN REPORTS OF THE TESTING AND COMMISSIONING RESULTS.

ABNORMAL CONDITIONS OF TURBINE GENERATOR

1. THE CONTRACTOR SHALL ALSO CONNECT TRIP SIGNALS TO BREAKER 'CG1' FROM DRY CONTACTS PROVIDED IN THE TURBINE/GENERATOR CONTROL CONSOLE BY ITS MANUFACTURER. SETTINGS FOR THE PROTECTIVE TRIP SIGNAL FROM THE CONTROL CONSOLE SHALL BE AS

PROGRAMMED BY THE TURBINE/GENERATOR MANUFACTURER.

2. IF AFTER THE EXPIRATION OF A ONE SECOND DELAY A TRIP OF BREAKER 'CG1' HAS NOT BEEN SENSED IN RESPONSE TO THE TRIP SIGNAL FROM THE TURBINE GENERATOR, THE TURBINE GENERATOR CONTROL PANEL SHALL SEND A BACKUP TRIP SIGNAL TO BREAKER 'CG2'.

DURING UTILITY OUTAGE PERIOD AND RESTORATION

1. THE TURBINE/GENERATOR SHALL REMAIN OFFLINE FOR THE DURATION OF THE OUTAGE.

2. AFTER RESTORATION OF THE UTILITY SOURCE A DELAY PERIOD OF 15 MINUTES SHALL BEGIN DURING WHICH TURBINE RECONNECTION
