静态型无功补偿装置的应用

Application of Static Var Compensator

主要介绍了静、动态补偿装置、静态型无功补偿装置（SVC）,指出可控饱和电抗器、相控电抗器和相控高阻抗变压器等产品,具有造价低和运行维护简单等的特点。举例证,如红沿河核电厂220 kV施工电源自2007年投运以来,由于现场用电负荷较低,一直存在向系统倒送无功等问题,对无功倒送的原因进行了分析,并计算了补偿容量,提出采用静态型无功补偿装置进行无功调节的解决方案。

This paper mainly introduces the performance of the dynamicstatic compensator,static var compensator（SVC） which mainly includes controllable transducer,phase controlled reactor and phase controlled high-impedance transformers etc.,which are advantageous in low costs,and easy maintenance.Since 2007 when 220 kV power source station of Hongyanhe Nuclear Power Plant started to be operated,the problem of reactive power releasing has been existing due to low load.The reason of reactive power releasing is analysed and compensating capacity is calculated and consequently solutions are put forward by adopting SVC for reactive adjustment.
