Inverter type power station pilot protection device and method based on zero-sequence current resistance-capacitance components

The invention discloses an inverter type power station pilot protection device and method based on zero-sequence current resistance-capacitance components. The device comprises a system side circuit breaker which is disposed at the bus side of a booster station in a target inverter type power station connection line, and a system side control device which is in communication connection with the system side circuit breaker. The device further comprises a power supply side circuit breaker which is arranged on a power supply bus side in the target inversion type power station connection line and a power supply side control device which is in communication connection with the power supply side circuit breaker. According to the method, zero-sequence current on the bus side of the booster station in the target inversion type power station connection line and zero-sequence current on the bus side of a power supply in the target inversion type power station connection line are collected, logic judgment is carried out
