混合型有源电力补偿技术与实验研究

分析了混合型有源电力补偿技术的原理，提出了混合型有源补偿与常规并联有源滤波器在直流侧电容电压、装置容量等方面进行比较的分析方法。分析表明，混合型有源补偿具有直流侧电容电压低、在补偿同等容量负荷条件下其逆变器容量远小于常规有源滤波逆变器容量的突出优点。对两者所进行的计算机仿真结果与理论计算值相吻合。最后，文中给出了50kVA样机的实验结果，验证了混合型有源电力补偿技术具有良好的补偿特性。

ANALYSIS OF HYBRID POWER COMPENSATOR AND ITS EXPERIMENTAL STUDY

The configuration and principle of a hybrid power compensator is analyzed.An analytical m ethod about the DC capacitor voltage,converter rating between the hybrid power compensator and the parallel active power filter is also presented.Analysis results show that the hybrid power com pensator has the prom inent advantages of the low DC capacitor voltage and the less converter rating. Moreover,the calculation results of the proposed method reasonably agree with the simulation data.In particular,results from a5 0 k VA hardware prototype are presented to verify the good com pensation characteristics of the hybrid power com pensator.
