无功补偿和混合滤波综合补偿系统及其应用

提出了一种具有功率因数校正、滤除谐波电流和抑制谐波谐振的电力系统综合补偿系统电路结构并将其成功应用于实际工程。无源支路在补偿无功功率的同时还可以滤除因非线性负载产生的特征谐波电流。为了抑制无源支路跟电网等效电感产生的谐振以及改善无源滤波器的滤波性能，系统中采用了谐振注入式有源滤波拓扑。论文对综合补偿系统的稳态补偿性能进行了详细的分析，并给出了系统的现场运行结果。理论分析和系统的现场运行结果证明了综合补偿系统的有效性和可行性。

Combined Compensation System With Reactive Power Compensation and Hybrid Active Power Filter and Its Engineering Application

A circuit topology of a combined compen- sation system for power factor correction, harmonic mitigation and harmonic resonance damping is proposed. The proposed topology has been used in practical engineering. The passive filter of the compensation system can be used for compensating reactive power as well as for mitigating harmonics caused by the nonlinear load. Further more, in order to damp the resonance between the passive filter and the equivalent inductance of the power network an injection type of active power filter is adopted. The steady compensation characteristics of the system are analyzed in detail. The feasibility and validity of the combined compensation system is verified by the theoretic analysis and practical operation results.
