基于综合考量的配电网供电可靠性评估

Power Supply Reliability Evaluation Based on Multi-level Distribution Network

考虑到之前配电网系统中针对0.4kV的配电网的状态分析效果差,可靠性不足的问题,为此提出一种基于多级层次的配电网供电可靠性评估方法。首先,通过载波技术来建立配电网用户和变压器的关系,其次建立多级层次法和熵权法融合的可靠性评估分析模型,通过输出的状态分析矩阵即可评估配电网的状态。最后通过某地实际配电网作为算例,验证本文提出评估方法的有效性和合理性。

Considering the poor state analysis effect and insufficient reliability of 0.4kV distribution network in the previous distribution network system,this paper proposes a power supply reliability evaluation method based on multi-level distribution network.Firstly,the relationship between the distribution network user and the transformer is established through carrier technology,and secondly,the reliability evaluation analysis model integrating the multi-level method and the entropy weight method is established,and the state of the distribution network can be evaluated through the output state analysis matrix.Finally,the actual distribution network in a certain place is used as an example to verify the effectiveness and rationality of the evaluation method proposed in this paper.
