摘　　要：有源电力滤波器(APF)的离线仿真只能保证控制算法正确,而无法反映实际运行时的动态性能。针对这一问题,建立了实时数字仿真器(RTDS)和APF联合的硬件在环(HIL)仿真系统并进行了相应的研究。介绍了APF的关键技术、RTDS的建模方案以及HIL仿真系统的组建策略,并详细分析了该仿真系统的运行环境。对比APF的PSCAD离线仿真、RTDS实时仿真、HIL仿真,结果表明HIL仿真系统能够反映实际运行中存在而在离线仿真中无法体现的诸多问题。在此基础上对采取补偿方法后的仿真结果进行了研究,表明HIL仿真系统能在本质上反映实际运行情况,能够真正检验APF的性能。The off-line simulation of APF（Active Power Filter） can validate only the control algorithm,but not the actual dynamic characteristics.A HIL（Hardware In the Loop） simulation system combining RTDS（Real-Time Digital Simulator） and APF is researched.The key technologies of APF,modeling scheme of RTDS and combination strategy of HIL simulation system are introduced,and its operational environment of HIL simulation system is analyzed in detail.The off-line simulation of APF with PSCAD,RTDS-based real-time simulation and HIL simulation are compared,which indicates that,HIL simulation system can reveal some problems existing in actual operation but not presented in off-line simulation.The simulation with compensation is studied,which demonstrates that the HIL simulation system reflects the actual operating conditions in essence and tests the APF performance truly.
