PMU数据处理及其在综合负荷建模中的应用
PMU Data Processing and Its Application in Compositive Load Modeling
摘要
Abstract
As the data obtained from the PMU is characterized by large volume and low sampling frequency, in order to meet the needs of composite load modeling, this paper presents a set of PMU data preprocessing methods including three key links: data selection, data integration and data interpolation. The paper gives a detailed introduction to the data processing flow and the theory and methods of data interpolation. To verify the availability of the PMU data preprocessing methods proposed in this paper, the authors make the practical composite load modeling with measured data collected from a 220 kV transformer substation, using the dynam ic load model made of 3-order induction motor in parallel with constant impedance. The results prove that the data processed by the proposed approach can satisfy the requirements of load model parameter identification.关键词
