吉天生. Research on CPR1000 Nuclear Power Plant Circulating Pump Tripping Protection Program Reform[J]. 2016, (3): 77-79+91. DOI: 10.16056/j.1005-7676.2016.03.018.
Single measuring point tripping pump logic was set in the pump
motor
gear box temperature
lubricating oil pressure and motor leakage detection in China improved three loop PWR(CPR1000)nuclear power plant circulating water system. These single tripping signals increased the risk of error tripping in circulating water pump
which seriously affected the stable operation of the unit. Five feasible kinds of tripping pump protection reform schemes were recommended
and the advantages and disadvantages were analyzed and studied. According to the actual setting of protection signal
appropriate pump protection scheme could be chose by the power plant
improving the availability and economical efficiency of the unit.
