【摘要】 对于大容量谐波与无功功率补偿,提出了采用混合型有源电力滤波器以及混合型滤波器与无源滤波器并联补偿的方式,分析了并联运行时混合型滤波器与无源滤波器之间相互配合进行谐波补偿的问题,提出了采用负载与系统电流检测适当结合的方式以改善谐波补偿效果的方法。计算机仿真结果验证了理论分析的正确性。更多还原

【Abstract】 For harmonic suppression and reactive power compensation of high power nonlinear load, methods of using shunt hybrid active power filter and parallel operation of hybrid filter with passive power filter are proposed. The coordination of the different devices are analyzed and a harmonic current detection method using the combination of load current and the mains current is developed for improving the performance of harmonic compensation and the resonance problem. The calculation results with the proposed methods are reasonable agreement with simulation data.更多还原
