摘　　要：针对传统并联型混合有源电力滤波器的有源部分需要承受电网基波电压,难以应用于中高压电网的缺点,分析了一种改进结构的兼具大容量无功补偿能力的大容量混合型有源电力滤波器,添加了基波谐振支路与有源部分并联以减小有源部分的基波分压,并通过无源滤波器组来补偿大容量无功功率。在分析了它的滤波原理之后,针对某冶炼厂大型整流装置谐波抑制和无功补偿的工程需要,以达到节能降耗、保证电网安全稳定运行为目的,分别就不同的工况详细介绍了兼具大容量无功静补能力的大容量混合型有源电力滤波器装置的主要组成设备和工程应用过程中的关键技术。仿真和现场应用效果表明文中研究的滤波装置能够满足现场需求,提高了供电功率因数,滤除了大部分谐波电流,达到了节能降耗、维护电网安全的目标。Traditional shunt hybrid active power filter （HAPF） is inapplicable to high power grid because it must endure fundamental voltage. To overcome the disadvantage, a novel kind of high capacity hybrid active power filter which suit high power grid by installing active power filter in parallel of fundamental series resonance circuits is proposed. Based on the analysis of its principle, in order to solve the problem that a smelter needs to suppress harmonics and compensate reactive power, this paper develops an installation and introduces the key techniques and composing of the equipment in detail. Simulation and application results validate the efficiency of the proposed equipment and techniques.
