利用PLC仿真软件来模拟锅炉辅机连锁保护系统

Use of PLC Simulation Software to Simulate the Chain Safeguard System in Auxiliary Engine of the Boiler

锅炉是发电厂的三大主机之一。锅炉在运行时,各辅机之间的关系十分密切,做好锅炉辅机连锁保护是非常重要的。因此,可以先利用PLC仿真软件来模拟锅炉辅机连锁保护系统,将现场设备模型化,以直观的形式模拟电厂生产现场辅机的保护连锁实际情况,并通过仿真结果,检验系统的可靠性。此方法简单易行,有利于辅机逻辑保护系统设计时使用。

The boiler is one of the three major engine in power plant. And the boiler in the operation, the relationship between the various auxiliary machine is very close, it is very important to complete the chain safeguard system of boiler auxiliary engine,.Therefore, We can use the PLC simulation software to simulate the chain safeguard system of boiler auxiliary engine, It makes site equipment modeling, through the intuitive form to simulate the actual situation of chain equipment method is is in the operation, and through the simulation simple, be helpful for auxiliary logic protection safeguard when the power plant auxiliary results to check the reliability of system. This system design when used.
