配电网PMU的P类性能指标设定研究

Research on P-class performance index setting of distribution network PMU

近些年来,为应对可再生能源大量接入配电网可能引发的电网安全问题,面向配电网的同步相量测量技术得到快速发展。为加速和规范配电网同步相量测量单元(DN-PMU,Distribution Network Phasor Measurement Unit)的研制,制定DN-PMU的测量标准或技术规范成为当前较为紧迫的任务。针对DN-PMU要求快速响应的应用场景,研究向主动配电网P类DN-PMU性能指标的制定。通过对基于DN-PMU测量数据的应用进行分类并筛选出典型应用,从应用需求方面提出P类DN-PMU的测量性能指标;基于主动配电网典型应用的信号环境,选用DN-PMU高性能测量算法从测量能力方面评估所提出性能指标的可行性,并由此对指标做进一步修订,对DN-PMU测量标准制定具有重要参考价值。

Recently,in order to deal with the security problems of grid operation caused by the massive access of renewable energy to the distribution network,the synchrophasor measurement technology for the distribution network has been rapidly developed.To accelerate and standardize the development of the distribution network phasor measurement unit(DN-PMU),the formulation of measurement standards or technical specifications for DN-PMU has become a relatively urgent task.This paper focuses on the application scenarios where DN-PMU is required to achieve rapidly response,and studies the formulation of application-oriented P-class DN-PMU performance index for active distribution network.Firstly,by classifying applications based on DN-PMU measurement data and selecting typical applications,the application requirement-based measurement performance index of P-class DN-PMU is proposed from the aspect of application requirement.Secondly,based on the signal environment of typical applications of active distribution network,we select high-performance measurement algorithm of DN-PMU to evaluate the feasibility of the proposed performance index from the aspect of measurement capability,and make further revision to the index accordingly.The work in this paper has important reference value for the final formation of DN-PMU measurement standards.
