| With the development toward large capacity and high paramenter of unit , theelectrical automation level is increasingly emphasized in the power plant. However,theautomation level of electrical monitor and controller is still lower due to traditionalreason. Against to the situation of the difference of control level between electricautomation and thermal process automation in power plant, the Power plant electricsupervisory system based on CAN bus and Ethernet is designed in this paper. The paperintroduces the current status of the power plant electrical automation.Based on theanalysis of electrical system's specialty and the system function demand, the hardwarestructure of electrical supervisory and management system in power plant was designed.Then on the basis of the hardware structure, the software system was developed. Thedesign of real-time database is elaborated with emphasis.The real-time data is stored bythe way of Memory database. The strategy of communication is analyzed. The system'ssoftware struction and concrete design are elaborated. |
