Research on Protection Technology of Energy Storage Power Station System

In order to ensure the safe and stable operation of energy storage power stations, this paper studies the short-circuit faults and protection schemes of energy storage power stations. First, a simulation model of the energy storage power station is established in the PSCAD/EMTDC platform, and the topological structure and working principle of the new all-solid circuit breaker are briefly described. On this basis, a protection scheme for the energy storage power station is designed, and the circuit breaker protection effect of short circuits within and between clusters is simulated and verified. Finally, the control and protection strategy and parameters of this type of circuit breaker are optimized, and the breaking effect is significantly improved.
