What Is The Role Of DC Power Supply System in Substations
Jul 20, 2024| The DC power supply system mainly plays two roles in substations: one is to provide DC power for high-voltage AC systems, and the other is to provide reliable DC power for protection and control systems. The specific introduction is as follows:
Stable High Voltage AC System: The DC system helps maintain the stable operation of the high voltage AC system by providing a stable DC power supply, combating issues such as voltage and current fluctuations and harmonics.
Support protection and control systems: Key equipment such as protection relays, control relays, and signal acquisition devices rely on reliable power supply from the DC power system to ensure the safe and stable operation of the power system.
Emergency power supply: In the event of an external AC interruption, the DC power supply system continues to be provided by the battery pack to ensure the normal operation of system equipment in emergency situations.
In summary, the DC power supply system plays a crucial role in substations, ensuring the safe, stable, and reliable operation of the power system.
