This paper first describes the basic principle of breaker failure protection, and analyzes the main factors affecting the delay of breaker failure protection. A technical scheme of breaker failure protection and dead-zone protection based on associated substation information is proposed. This scheme forms a current differential protection criterion by utilizing the non-faulty area circuit breaker CT which is adjacent to failure breaker. After the criteria of incomplete current differential protection are satisfied, the related circuit breaker is tripped to isolate the fault. This scheme is not affected by CT tailing and saturation, which greatly shortens the delay of failure protection and realizes the free protective setting. The implementation of the project adopts an expandable architecture designed with master slave mode, which is flexible in engineering configuration. Meanwhile, the protection sampling synchronization does not rely on external timing signals. This scheme has high reliability and is easy to carry out, so it has the practical significance of widespread promotion.
