Common faults of substation automation system and treatment

LI Zhen(Xiamen Extra High Voltage Power Transmission and Substation Bureau of Fujian Province,Xiamen 361004,China)  
The common faults existing in the operating substation automation systems are analyzed and summarized:communication network fault,data acquisition fault,false alarm and mismatch between devices from different manufacturers.Their causes are analyzed based on a mass of site data,including quality,communication interface,openness and so on,and the corresponding treatments and improvement measures are proposed.
