论文摘要
多年来，叠加的序列数量已依赖于保护方案中各种应用的纯断层组件。在最近的时间里，它们已被用于各种解决方案，以解决通过分布系统中分布式生成引入的挑战。为了提高这种主动分配网络中部署的保护方案的总体可靠性，本文评估了一种使用负序列数量来检测不平衡故障的新方法。提出的叠加层序列允许元素使用模拟社区微电网上的仿真测试验证。该方法的性能在MATLAB/SIMULINK中测试了各种故障方案。
Superimposed sequence quantities have been relied on for years to provide pure fault components for various applications in protection schemes. In more recent times, they have been employed in various solutions to the challenges introduced by integration of distributed generation in distribution systems. To improve the overall reliability of protection schemes deployed in such active distribution networks, this paper evaluates a new approach for detecting unbalanced faults using negative sequence quantities. A proposed superimposed negative sequence admittance element is validated using simulation tests on a modelled community microgrid. The performance of the method is tested for various fault scenarios in MATLAB/Simulink.
