【摘要】 根据智能电网的实际特点,加入故障的随机因素影响,特别是考虑了故障的否定信息判定因素,提出一类直觉不确定粗糙集及其约简算法,实现了对于智能电网故障诊断原始规则的约简方法设计。智能电网中的各个重要条件属性被合理地转化为直觉不确定粗糙集形式。系统在西藏日喀则电网的应用表明了该方法的有效性。
【Abstract】 To deal with the uncertainty and deferent structures of the intelligrid,rough sets and intuitionistic fuzzy sets were introduced.Based on them,intuitionistic uncertainty-rough sets were proposed and the reduction algorithm was improved.The rule reliability was deduced using intuitionistic fuzzy sets and probability.The application for Xigaze power system in China’s Tibet shows the effectiveness and usefulness of the approach.
【Key words】 intelligrid; fault diagnosis; rough sets; intuitionistic uncertainty sets;
