| 摘 要： | 作为电力系统无功优化规划基础的现状无功评价尚未受到足够重视的问题,故提出科学实用的城市电网现状无功评价体系和评估方法.通过对AHP实施改进来克服原AHP标度重要排序过程的不确定性,以及权重计算和一致性校验的复杂性,将Delphi法和改进AHP相结合构造了城市电网现状无功评价体系.在此基础上,建立旨在系统全面分析无功方面存在问题的现状无功综合评估的流程.某城市电网无功的评价结果表明了该方法的有效性和实用性.

| Abstract: | As the foundation of reactive power optimization and planning,actual reactive power evaluation has not been widely conducted.A practical comprehensive hierarchy and method for reactive evaluation is presented.First,the proposed improved Analytic Hierarchy Process(AHP) can satisfy the indeterminacy of the sort process in basic AHP and the complexity of the weigh coherence verifying;next,reactive power evaluation hierarchy is built by associating Delphi and improved AHP; then,the evaluation flow is establishe... |
