Criticality means the failure probability of the equipment is very high. The miner failure of critical equipment may leads to s...

Abstract: Equipment maintenance is one of the core tasks in power system operations. The premise and foundation for maintenance is to establish a power equipment maintenance model, which should reflect all equipment states accurately including operation, inspection and maintenance. On the basis of the analysis of the traditional state diagram probability model, an improvement is put forward to ...
