Automated capacitor control program
Automated Capacitor Control Program

  • Why capacitor automation?

  • TXU ED’s capacitor automation system requirements

  • System architecture

  • System implementation considerations


Why capacitor automation
Why Capacitor Automation ?

  • Capital savings on future capacitor additions

  • Reduced O&M costs

  • Manpower savings

  • Improved utilization of assets

  • Ability to adapt to changing system needs

  • Compensate for customer supplied capacitors

  • Easier to make control setting changes

  • Increased availability of information on capacitor bank status and operation

  • Information available in a timely manner

  • System reliability and losses


Txu ed s capacitor automation system requirements
TXU ED’s Capacitor Automation System Requirements

  • Centralized control

  • Support multiple communications modes

  • Control logic based on VAR flow limits using existing substation feeder/bank information (watts, VAR, voltage)

  • Provide centralized control for Non-LTC stations (voltage control primary - VAR secondary)

  • Identify specific banks requiring maintenance

  • Provide information on the availability of capacitors

  • Identify feeders with excess or deficiencies of capacitors at peak conditions

  • Backup local control logic

System implementation considerations
System Implementation Considerations

  • Field trial – size and time frame

  • Inform all groups effected by the project to gain support and get feedback

  • System implementation time schedule - allow for issues identified during initial stages on project

  • Manpower requirements for installation of controls and setup of central system (excellent OJT opportunity for system operators)

  • Project implementation procedures which verify and document proper operation of all system components

  • Field installations

    • Minor repairs identified during control installation

    • Who will perform control installations?

    • Detailed installation and documentation procedures

  • Provide adequate training for installers and emphasize need to follow procedures


System implementation considerations cont d
System Implementation Considerations (cont’d)

  • Manpower shift with centralized control

  • Who will run the system?

  • Manpower requirements for day to day operation

  • Maintenance procedures for banks identified by system in need of maintenance

  • Contingency plans if central system goes down

  • Changes in inspection cycles

  • Reports to management
