| 摘 要： | 提出了一种基于最小二乘法的模糊故障选相序分量的相关分析法。首先提出基于电流相关分析的选相算法，并分析其优势和不足，然后在其基础上提出基于模糊理论电流与电压相结合的选相算法，有效的解决了在发生转换性故障出现的误选现象，最后通过PSCAD仿真验证了该综合选相方案的有效性，大大提高了在高阻接地时选相的灵敏度和两相接地短路的可靠性。

| Abstract: | A correlation analysis based on fuzzy fault selection phase of least square method is put forward in the paper.First,the selection phase algorithm based on current correlation analysis is proposed and analyze its advantages and shortcomings.Then on the basis of this,the selection phase algorithrm based on fuzzy theory combination of current and voltage is propsed,it is effective to solve error selection when commutation fault appears.Finally,the feasibility of the synthetic selection phase is verified by PS... |
