Tinggang Jia · Dianli zidonghua shebei · 2008
The power plant SCADA system constructed by stages should adopt open system structure,standard communication interface and object -oriented configuration software to reduce the difficulty,risk of later construction stages,and the project investment.From system function design and project construction,the overall concept of system development and implementation is proposed.The system structure design,man -machine interface development and communication protocol transformation are introduced in detail and the implementation solutions are given for some special functions,such as synchronous parallel -in of generator,automatic switchover of spare source,etc..System reliability is enhanced in both HW and SW:redundant communication channels are equipped for all IEDs and monitoring system;on -line fault diagnosis and automatic changeover of monitoring system are realized by script language program.
