Embodiment Construction
[0067] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0068] A layered and domain-based anti-islanding protection method for large-scale wind power generation, including:
[0069] S1. Monitoring the tripping signals of all circuit breakers set in the wind power generation system;
[0070] S2. Judging by the tripping signal of the circuit breaker of the cluster master station whether the tie lines sent by the cluster master station and the main transformer are all disconnected, and protecting the island formed by the disconnection of the tie line sent by the cluster master station and the main transformer;
[0071] S3. Judging whether an isolated island is formed by a transformer fault in the booster station through the...
