| 摘 要： | 分布武电源的接入和固态限流器的采用使传统的配电网故障分析方法已不能满足未来分布式发电系统的需求。针对含分布式电源的配电网故障展开研究，提出了一种含固态限流器的分布式发电系统故障计算新方法。该方法无需形成配电网节点复数导纳或阻抗参数矩阵，可方便计及固态限流器及短路点接触电阻的影响，避免了复杂的序网连接。采用20节点算例对所提方法进行了测试，算例结果证明了该算法的可行性和有效性。

| Abstract: | Traditional fault analysis method of distribution networks cannot meet the requirement of distribution generation system （DGs） with solid-state fault current limiters. In order to solve this problem, a new method for calculating short circuit fault of distribution system with DGs and solid-state fault current limiters is presented in this paper. The method of this paper has the following characteristics： （1） the nodal complex admittance matrices of the network are avoided in fault calculation; （2）it is very simple to treat the influence of the solid-state fault current limiters and the faulted point resistor; （3） the complex connections between sequence networks are avoided in fault calculation. Test results of 20-node test system verified the feasibility and effectiveness of the proposed method. |
