不同负载工况下牵引变对电网电压不平衡的影响
Research on the influence of traction transformer in different load conditions on voltage unbalance in power supply system
摘要
Abstract
In view of the unbalanced voltage problem in power system caused by electrified railway accessing to public substation,A 36-node grid test system and a variety of traction transformers were established on the platform of PSCAD,and the propagation condition of unbalanced voltage caused by electrified railway was analyzed.The voltage unbalance effect on the power system when it connecting traction transformers with balanced or unbalanced load under the condition of alternation commutation phase was researched.The study finds that the rational deployment of traction load can reduce the VUF of PCC less than 2%.The research result of simulation analysis provides theoretical support and engineering application value for transformer selection and load deployment.关键词
