Substation Computer Anti Mistaken For System Design And Realization

The embedded system is developed so far that the system structure which combines with PC for gather, communication, control, save and operation has been more and more accepted and applied.The transformer substation mistake precaution system is designed for the "Five Rules" during the operation in the substation. It is a communication system based on the communication bus, which has the function of embedded gathering and controlling system, and mistake precaution software on PC. This system delivered to the transformer substation and was confirmed during the operating on the spring and autumn overhaul. The system was awarded a second prize of scientific and technical result of the Northeast power administration bureau.This paper introduces the transformer substation mistake precaution system simply, and presents the needs and function modules at the very beginning. Then it begins to introduce the design idea of system hardware in modules, and the testing results. In the third part of this paper, software design idea and the safety strategy for the whole information system are brought forward. It also sums up the problems existing through the developing, testing, test running and maintaining course, and the resolving method. In the forth part, the transformer substation mistake precaution system which works under the CEDnet is put forward. In this part there are also the application needs, function division, module division and implementation. At the end, it gives a simple introduction of nobody on watch transformer substation.
