Vv接线牵引变电所电能质量治理方案研究

Vv接线牵引变压器具有接线简单,容量利用率高,投资少的特点,在我国普速和高速电气化铁路中应用较广。但该变压器存在负序含量大,影响三相电力系统电能质量,随着未来机车负荷功率的增大以及发车密度的增加,电能质量问题不容忽视。因此研究该接线形式牵引变压器负序特点,在此基础上进行负序、无功等电能质量治理方案,为彻底解决我国Vv接线牵引变压器高速电气化电能质量问题具有重要的意义。同时针对电气化铁路特有的过分相问题,研究一种既能治理电能质量问题又能解决变电所处过分相问题的综合治理方案,进而实现同相供电,将是电气化铁路未来重要的发展方向。      
本文将了解Vv接线牵引变压器负序特点;针对Vv接线牵引变压器负序特点,提出相应的负序治理方案;研究Vv接线牵引变压器构成的同相供电方案。研究手段:理论分析+仿真验证。完成毕业设计论文。

Abstract

Vv wiring traction transformer with a simple wiringhigh capacity utilizationless investment characteristicsin China's speed and high-speed electrified railway applications in a wider range. Howeverthe transformer has a negative sequence contentaffecting the three-phase power system power qualitywith the future locomotive load power increases and the increase in traffic densitypower quality problems can not be ignored. Thereforeit is important to study the negative sequence characteristics of the traction transformerand to carry out the negative quality control scheme such as negative sequence and reactive power. It is of great significance to solve the high quality electrification power quality problem of Vv wiring traction transformer in China. At the same timeaiming at the problem of over-phase of the electrified railwayit is necessary to study the comprehensive treatment scheme which can deal with the problem of power quality and solve the problem of substation in substationand realize the same phase power supplywhich will be the important development direction of electrified railway.
In this paperwe will understand the negative sequence characteristics of Vv wiring traction transformer. According to the negative sequence characteristics of Vv wiring traction transformerthe corresponding negative sequence control scheme is put forward. The in-phase power supply scheme of Vv wiring traction transformer is studied. Research MethodsTheoretical Analysis + Simulation Verification. Complete graduation thesis.
