Design And Application On The System Of The Harmonic Waves Pollution Observation In Suzhou Electric Fence And Electrified Railways

In recent years,with the increasingly wide usage of nonlinear electronic device,a great number of harmonic waves are produced in the electric fence.Electromagnet load is a typical source of nonlinear harmonic waves.The open of Beijing-Shanghai and Longhai electrified railways give a certain effect on Suzhou electric fence.Therefore,it is necessary for us to observe and analyze the harmonic waves in electrified railways,and make some relevant control measures.This passage mainly studies on a object of Suzhou electric fence and electrified railways in Anhui provice,lucubrating and discussing the four aspects of the current situation of Suzhou electric fence,power supply mode of electrified railways' sites,pollutions of harmonic waves in electrified railways and their effects on the electric system and the work of building an online observe system for the power quality.And this passage also proposes a set of pertinent integrated management approaches to control and reduce pollutions from electrified railways to the whole electric fence,to minimize pollutions from harmonic waves to electric fence for higher power quality,and also to create a favorable electric environment and promote the development of local economic.
