摘要
针对农网中存在的低电压问题,提出了一种基于晶闸管的动态低电压补偿器技术方案。该方案通过并联多抽头变压器取能,控制晶闸管选取次级相应抽头电压,利用串联变压器将该电压注入至电源与负载之间的供电线路。对该方案的工作原理及补偿策略进行深入讨论,并通过验证样机的10 kV实验结果验证了该方案的正确性及有效性。
A dynamic thyristor switched low voltage compensator is proposed for the low voltage problem in rural distribution system.In this scheme, the compensator voltage is selected by thyristor switching tap in secondary winding of shunt staged transformer, and injected to power supply line between power source and users for compensating voltage drop.Then,its operating principle and compensation strategy are discussed,and its validity and effectivity is verified by the prototype experimental results in 10 kV.
