【摘要】 利用静止无功补偿装置实现动态无功功率补偿的研究是目前电力电子学科中比较活跃的研究领域之一。本文对先进的无功补偿装置——新型静止无功发生器(ASVG)进行了深入分析和研究。 论文首先比较了现有的无功补偿装置，分析了ASVG的优越性能。根据ASVG的动态补偿原理，论文讨论了其补偿性能。其次，论文总结了电流间接控制和电流直接控制中的典型控制方法，分析了这几种控制方法的优缺点。另外，论文还介绍了瞬时无功功率理论及其在无功控制和无功检测方面的应用。 论文重点对电流间接控制中的逆系统PI控制和电流直接控制中的dq轴电流控制进行了详细研究，仿真了ASVG在这两种控制方法下的静态和动态特性。仿真结果表明，与电流间接控制相比，电流直接控制在电流跟踪速度、控制精度等方面更具优势。 最后，针对电流直接控制，开发了基于高速数字信号处理器(DSP)的硬件控制平台，设计了±10kvar ASVG实验系统，进行了实验研究，得出了ASVG稳态和动态实验结果，并对实验结果进行了分析。更多还原

【Abstract】 At present, the research on compensating reactive power using static compensation device is one of the most active areas in power electronics subject. In this thesis, the advanced compensation device - Advanced Static Var Generator C ASVG ) is studied and analyzed deeply.Firstly, the existing compensation devices are compared and the ASVG’s superior performance is analyzed. In this thesis, the compensation performance of ASVG is studied according to dynamic compensation theory. Secondly, several typical control methods are summarized and their advantages and disadvantages are analyzed. In addition, the instantaneous reactive power theory and it’s application to reactive power control and detection are introduced.In this thesis, current indirect control with the reversible system PI and current direct control under dq axis are studied specially and the static state anddynamic state performances of ASVG controlled by this two method are simulated respectively. The simulation results show that, compared with the indirect control, the direct control has more superior performance in current tracking speed and control property.In the end, a hardware platform based on DSP is carried out and the ?lOkvar ASVG experimental system is designed. The experiment is realized based on the current direct control and the result is analyzed.更多还原
