| 摘 要： | 基于电压补偿型超导故障限流器(SFCL)的工作原理,分析了电网故障时由于限流器限流阻抗串入对电流保护的影响.通过重新整定电流保护的动作值,得到了限流器与电流保护配合的解决方法.以一个10kV中性点不接地配电网为例,分别对引入SFCL前后系统三相短路的电流保护进行仿真,验证了该方法的有效性.

| Abstract: | Based on work theory of voltage compensation superconducting fault current limiter(SFCL),the influences of the limiting impedance in series of the SFCL on current relay as power network taking place a fault were analyzed.The solution of SFCL coordinating with current relay was proposed through resetting the action current of the relay.As an example of 10kV isolated neutral distribution network system,the influences of current relay under three-phase short-circuit with SFCL and without SFCL were simulated re... |
