Abstract: Abstract: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.
