摘要：
Aiming at the problem of sending-end AC overvoltage caused by commutation failure in wind farm via line commutated converter based high voltage direct current (LCC-HVDC) grid-connected system, a reactive power decentralized cooperative control method is proposed. First of all, the AC voltage and surplus reactive power characteristics of the point of common coupling (PCC) at the sending-end AC system during the commutation failure period are analyzed. Then, starting from the reactive power and voltage characteristics at PCC, the trigger angle value of LCC rectifier station and reactive power reference value of wind farm station based on their own power and voltage characteristics are determined respectively by using the reactive power-voltage coupling relationship and AC-side power flow equation. The purpose of cooperative suppression of overvoltage at PCC is achieved by decentralized control of LCC and wind power station. Finally, the model of wind farm via LCC-HVDC grid-connected system is built in PSCAD/EMTDC and the simulation research is carried out. The results show that the proposed decentralized cooperative control method can effectively restrain the AC overvoltage level during the recovery period after commutation failure. © 2024 Electric Power Automation Equipment Press.
