摘　　要：针对实际电力系统进行了常规零序电流保护与自适应零序电流保护的整定和灵敏度计算。由于自适应零序电流保护能够自动跟踪系统的运行状态,因此计算结果表明,与传统零序电流保护相比自适应零序电流保护其保护范围更大、灵敏度更稳定。The setting and sensitivity calculation of conventional zero-sequence current protection and adaptive zero-sequence current protection setting calculation are carried out for the actual power system.Since the adaptive zero-sequence current protection can automatically track the running state of the system,the calculated results show that compared with the traditional zero-sequence current protection,the adaptive zero-sequence current protection has larger protection range and more stable sensitivity.
