Review of AVC Coordinated Control Strategy for Condenser

Compared with other reactive power equipment, the new generation of condenser can provide dynamic voltage support through forced excitation, reduce the risk of commutation failure of DC system, and suppress voltage fluctuation by using the secondary transient characteristics of the condenser, and the system voltage can be recovered quickly. The new type of large capacity condenser can improve the static voltage stability margin of the system, improve the transient voltage stability level of the system, and solve various types of voltage stability problems of the sending end power grid; during the steady-state operation, the condenser can also maintain the voltage stability as a regional voltage regulation means. Therefore, it is necessary to study the AVC control strategy of the condenser
