基于熵权法和灰色关联度的中压配电网供电水平关键性指标研究

Research on Key Indexes of Power Supply Level of Medium-voltage Distribution Network Based on Entropy-weighted Method and Grey Relational Degree

依据电网结构现状,采用熵权法和灰色关联度相结合的方式进行电网供电能力评估,依据本文的评估模型可实现电网中电源设备、线路和配变设备的供电能力,综合各设备的运行状况和运行指标,完成电网的评估,为电网可靠性运行和电网资源合理分配提供了一种新的思路。

Based on the current situation of power grid structure,this paper uses the method of entropy and gray correlation to evaluate the power supply capacity of the power grid.According to the evaluation model of this paper,the power supply capacity of power supply equipment,lines and distribution equipment in the power grid can be realized.Integrate the operation status and operational indicators of each equipment and complete the evaluation of the power grid,which provides a new idea for the reliability operation of the power grid and the rational distribution of power grid resources.
