The paper mainly researches how to use the expert system to reason out the orders of the switching operations correctly and provide a convenient interface for viewing and editing the switching operations for Shangan power plant. After analyzing the applied objects carefully, it sets up repository,regulation base and inference engine, and forms all kinds of operation tasks utilizing the reasoning technique of expert system. On the given interfaces, operators may select operation tasks and other configuration options, and the corresponding operation contents would be formed automatically after the five-prevention estimation. According to the idea of separating repository,regulation base and inference engine, this system will be managed easely .Moreover, the worker can reason out the switching operations on the line graphic of the power plant and manage the switching operations in the network, so these functions make this system become more perfect, more efficacions and more advantage. |
