摘　　要：采样值差动在母线保护运用中对非典型故障存在灵敏度差的问题。为此,通过仿真与动态模拟试验,论述了电流差动原理,进行了复杂故障的模型、数据及原理分析,针对母线非典型故障,提出了将采样值差动保护与稳态相量差动保护相结合的解决方案。Sampling value differential protection for buses is of poor sensitivity to nontypical faults. Therefore, through simulation and dynamic simulation test, the principle of current differential protection is expounded, and the model, data and principle of complex faults are analyzed. Aiming at nontypical faults of buses, a solution combining sampling value differential protection and steady-state phase differential protection is put forward.
