摘要
介绍了潍坊发电有限公司Ⅱ期2台670MW机组压力控制阀(PCV)的使用情况,指出了PCV存在误动作的问题并提出了改造方案,利用新华XDPS虚拟分散处理单元(DPU)对其功能进行了仿真。
The usage conditions of the pressure control valves of two 670 MW units in Huadian Weifang Power Generation Company Limited were introduced. The problem of PCV malfunction was pointed out,and the reformation scheme was put forward.Using the virtual distributed process unit( DPU) of Xinhua distributed processing system( XDPS),the function of reformed PCV protective device was simulated.
