提出一种新型静止无功补偿器的拓扑结构及相应的控制方法。为了提高装置的补偿性能,引入了重复控制。针对10kV电网系统的10MVA不控整流负载,设计了新型静止无功补偿系统。仿真结果表明:新型静止无功补偿器能有效抑制无源滤波器与电网发生的谐振,具有谐波补偿精度高、响应快的特点,适用于高压大容量无功功率和谐波补偿的场合。 A novel static var compensator topology and corresponding control methods are proposed. In order to improve the compensation performance of the device, repeated control was introduced. Aiming at the uncontrolled rectifier load of 10 MVA in 10 kV power system, a new static reactive power compensation system is designed. The simulation results show that the new static var compensator can effectively restrain the resonance of the passive filter and the power grid, and has the advantages of high harmonic compensation accuracy and fast response, and is suitable for high voltage and large capacity reactive power and harmonic compensation.
