  • PCS-9700R AGC/AVC

  • NR Electric supplies Automatic Generation Control (AGC) and Automatic Voltage Control (AVC) optional advanced functions for renewable energy Stations.

    AGC is used to automatically maintain the system frequency or the power flow of interconnection lines within the target range. AGC operates based on the control of each generation unit in the farm dynamically and continuously. It regulates the power generation according to the entire plant power generation plan or strategies.

    AVC is realized by controlling the reactive compensators installed in the power plant. In the control zone, reactive power or voltage control strategies are online calculated based on the real-time operation data of the power grid or the regulation targets given by the control center or grid dispatching center. Relying on the calculated strategies, reasonable reactive power or voltage operation states are realized through the automatic closed-loop control of the reactive power or voltage regulation equipment.
