摘要
本文在以往提出的同相供电系统概念和理论基础上,论述实现同相供电的关键技术问题,即对称补偿的基本原理和实现模式。文中,把对称补偿分为全可调、半可调和不可调三种模式,通过无功(功率因数)、负序电流、谐波和牵引母线压损补偿的技术性能分析,给出了有益于实际应用的结论。
On the basis of the concept and the theory of the tractionfeeding system without phase exchange earlier proposed by the author,the present paper discusses the basical principle and the realizationmodes of symmetrical compensations, a key technique to realize the newtraction feeding system. Symmetrical compensations are classified asthree types, i. e. fully adjustable compensation,partially adjustable com-pensation and fixed compensation. Some useful conclusions have benedrawn through analysing the compensated power factor, the negative-phase sequence, harmonics, busbar voltage loss and other technicalperformances.
