Study on electrostatic precipitator fault detection system

Electrostatic precipitator needs every kinds of important information of whole system, especially system fault information, to run stably. This paper analyzes back corona fault and place-line distance shorten failure by PRONY method, which are two indiscriminative faults of electrostatic precipitator. The research result shows that PRONY method can distinguish these two faults efficiently, which can redeem the inefficiencies of traditional methods.
