摘要
国内外对暂降源定位方法的研究已趋于成熟,然而新能源广泛的发展对电力系统稳定运行增加了风险外,还影响着传统多测点定位方法的准确性。近年来对高渗透新能源电网暂降源定位法的研究分为三类:扩展阻抗测距法、配电开关监控终端(Feeder Terminal Unit,FTU)故障信息定位法、神经网络法。阐述这三类方法并分析其不足,随后提出基于新能源电源机理特性的新型定位法的研究思路,最后考虑如何优化电力系统规划和运行中存在的不确定因素。
The study for the temportary drop sarce positioning mode at home and abroad has ripened,but the development of new energy source to risks of stable operation of the power system has increased,and effects accuracy of traditional multiple-measuring point positioning mode.In recent years,the study for the power network temportary drop source positioning mode of hypertonic new energy source has been divided into three kinds:expauded impedance distance-measuring mode,fault information positioning mode of feeder termial unit and nearal network mode.The paper expounds the three kind modes and analyzes their stortages,and then puts forward a study thinking based on a new kind ploitioning mode of new eaergy source mechanigm characteristic.Finally consider how to optimize uncertain facts which are in the power system and operation.
