基于关键量测辨识的配电网可观测性分析

Observability Analysis of Distribution Network Based on Key Measurement Identification

目前配电网量测配置严重不足,导致配电网中量测信息不足、可观测水平极低。在配电网中增加测量设备,可提高网络的可观测能力,但考虑到经济性,在所有支路和节点处增设量测装置显然不可取。对此,以提高配电网的可观测性为目的,研究如何选择某些关键量测,既能保证配电网的可观测性,又能减少设备投入,对配电网增设量测装置具有很好的参考意义。

At present,due to the shortage of the measurement configuration in distribution network,the measurement information is insufficient and the observable level is very low.Increasing the measurement equipment in the distribution network can develop the distribution grid.However,given the economic nature,it is obviously undesirable to add measuring equipment to all branches and nodes.Therefore,this paper studied how to select some key measurements,which could not only ensure the observability of distribution network,but also reduce the input of equipment.This study had a good reference meaning for the additional measuring device of distribution network.
