文摘Electrified railway is an important but disturbing load in power system. In China railway electrification is gaining momentum at the end of this century.The Ministry of Railway has a clear indication that the development trend of railway transportation is the coexistence of internal-combustion engine locomotive and electrified locomotive.

It is obvious that the importance of electrified railway in railWay transpoftation will be enhanced more and more. It is going to be an important load to power systems all over China.
