“…In Figure 1, the reliability model of the relay protection equipment is merged with the circuit breaker model, and is no longer analyzed as a separate component. This not only takes into account the fault rate of the relay protection equipment, but also simplifies the algorithm [2,3]. Assuming that all components are repairable, no matter what faults occur in the components, they must be repaired, so the transformation of each state is through planned maintenance status.…”

The reliability analysis and calculation of the electrical main wiring is not only the core content of the electrical design of pumped storage power stations, but also provides a theoretical basis for the selection of the electrical main wiring of pumped storage power stations. This paper considers pumped storage power plants as a whole, taking into account the reliability model of relay protection devices and random faults of various components. When establishing a reliability indicator system, this paper considers two operating conditions: power generation and pumping. The proposed model and algorithm are verified and calculated according to a concrete engineering case.
