摘　　要：动态无功补偿是提高电网运行安全性和稳定性的有效手段。当前的特高压交直流电网中,受端电网的稳定性和直流输电系统存在相互作用,利用动态无功补偿可以增加受端系统的强度,提高电压和频率的稳定性。所以研究不同动态无功补偿装置的能力对理解大电网稳定性非常重要。本文对3种典型的动态无功补偿装置同步调相机(SC)、静止无功补偿器(SVC)和静止同步补偿器(STATCOM)的功能进行了系统的介绍和讨论。通过解析推导和数字仿真相结合的方法,对这些补偿装置的性能进行了详细的评述。本文的结论可用于指导用户设计和选择合适的无功补偿装置,为保障电网稳定运行提供有效手段。Dynamic reactive power compensation is an effective means to improve the safe and stable operation of power grid.In the current UHV AC/DC grid,the stability of the receiving end power grid interacts with the DC transmission systems.The use of dynamic dynamic reactive power compensation can increase the strength of the receiving end system and improve stability of voltage and frequency.It is therefore important to study the capability of various dynamic reactive power compensation devices to understand the stability of large power grids.In this paper,the functions of such three typical dynamic reactive power compensation devices as synchronous capacitor(SC),static var compensator(SVC)and static synchronous compensator(STATCOM)systematically introduced and discussed.Through the combination of analytical deduction and digital simulation,the performance of these compensation devices is reviewed in detail.The conclusion in this paper can be used for the customers to design and choose the appropriate dynamic reactive power compensation devices and provide effective means to ensure the stable operation of power grid.
