The research of a long range supervisory and control equipment for lOkV switch in this paper is a part of the distribution automation. It is also called the feeder automation. This paper presents the technology of fault handling for the long range supervisory and control equipment, the design of software and hardware for terminal, the choice of the communication agreement and the structure of communication net, the choice of the arithmetic for fault judging . The data terminal is based on DSP and single chip computer. Between terminals and transformer substation units, the communication network is based on CAN field bus. It can increase the reliability of communication and reduce the investment in lines. The system monitors feeder block switch and state , feeder electric current, voltage situation of getting in touch with the switch in real time in the distant place in normal cases, realize that shuts the floodgate and divides the floodgate to operate in the distant place of the circuit switch; Obtain trouble write down , differentiate and isolate feeder trouble sector and resume to trouble area supply power automatically at trouble.Li Yan (Power System Automation) Directed by Prof. SongWei...
