Substation Control Room

Summary

Key Points

• —The video offers an introduction to a 230 kV high voltage substation control room, highlighting the almost identical panel board configurations across different substations. 0:30
• —The control room features distinct control panel boards for both the 230 kV and 33 kV lines, managing incoming, outgoing, and coupling bays. 0:57
• —Protection panel boards, installed behind the control panels, utilize Siemens relays such as differential, distance, and current relays to ensure substation safety. 2:18
• —The measurement panel board (Q) is dedicated to power metering, while the interface panel board (UB) serves as the entry point for all signals from the substation area. 3:21
• —The SCADA panel board (YV) receives signals from the interface panel and forwards them to the RTU panel board for transmission to dispatching. 3:45
• —Specialized panels include the AVR panel for line bays, the Fault Recorder (FR) for documenting faults, and the Event Recorder (ER) for logging all substation occurrences and status changes. 4:52
• —The RTU (Remote Terminal Unit) panel board is responsible for collecting all signals from SCADA and sending them to the central dispatching system. 5:37
• —The battery charger panel board supplies DC power to command circuits, while the UPS panel board provides an uninterruptible power output for critical systems. 6:01
• —The substation internal consumption panel board manages the power supply for the substation's own operational needs, drawing from auxiliary transformers. 6:13
