在电力系统中,通过无功电压补偿,可以大大提高电能质量。本文对磁阀式可控电抗器的基本结构和工作原理进行了研究。通过电力系统仿真软件Matlab/Simulink对其控制特性、伏安特性、谐波特性进行了全面分析。最后在其工作特性的基础上介绍了电抗器在无功补偿中的应用,以快速响应的磁阀式可控电抗器和并联电容器组成的补偿元件,配以相应的快速无功检测环节组成的无功补偿系统,可以保证补偿的快速性、准确性和合理性。

In powersystem,quality of power supply can be improved greatly by the synthetic compensation of reactive power and voltage.In this thesis,the basic structrue and operation principle of magnetive valve controllable reactor are studied.The Matlab/simulink based simulation results analyse the control characterastic,voltage current characteristic,harmonic wave characteristic completely.Its application in reactive power compensation is introduced finally on the basis of working characteristic.The responsive reactor,shunt capacitor and reactive power check segment compose reactive power compensation device which can ensure rapidity,accuracy and rationality of reactive compensation.
