摘　　要：由于采用传统方法设计的无功补偿装置存在着不足,经常出现烧毁电容器或电抗器的事故,为了克服这些不足,提出了一种基于系统设计的方法进行无功补偿的设计。通过详细的理论推导以及这两种设计方法在具体工程中的应用对比分析和专用工程软件计算机仿真,仿真结果和前后谐波改善效果对比表明采用系统设计的方法能有效避免装置发生谐振而烧毁器件的危险现象。Var compensation device designed with traditional methods has shortcomingsoften causing accidents of burning the capacitor or reactor. To overcome these problems, a designof var compensation device based on system design method was put forward. Through detailedtheoretical analysis, comparative analysis of applications of the two design methods inactual projects, simulation with special engineering software and comparison of the simulationresults with improved performance of harmonics, it was revealed that using the system designmethod could effectively avoid the occurrence of resonance and the risks of burning elements.
