摘要
以工程应用为背景,结合注入式有源电力滤波设备在实际应用中存在的问题,提出了一种适用于中高压电力系统的串联谐振注入式混合型有源电力滤波器(SRIHAPF)的新型拓扑结构,该结构能够在电网电压畸变比较严重时仍然安全稳定工作,并通过基波谐振支路谐波分压和串联谐振支路谐波分流两个方面探讨了新型结构的优越性。在分析了SRIHAPF基本工作原理的基础上,对其主要工作特性进行了研究,包括谐波补偿特性、谐振抑制特性以及SRIHAPF系统稳定性。仿真和实验结果验证了理论分析的正确性。
According to the requirement of harmonic suppression and reactive power compensation in power system, a novel HAPF with series resonance circuit （SRIHAPF） is proposed in this paper, which is suitable for applying in high-voltage system. And the APF achieves satisfying compensation result even if the PCC voltage is badly distorted. The advantages of SRIHAPF are discussed. Then the steady compensation characteristic of the compensation system, the resonance damping and the stability of the system are analyzed in detail. The feasibility of SRIHAPF is validated by the theoretic analysis and simulation results.
