Abstract

This paper makes a contribution to the field of fault location finding in a new way that helps in the improvement of grid reliability. This paper proposes a study-based approach for fault allocation and fault type classification that uses the study of voltage and current frequency during the abnormal condition. Although, ideally frequency of voltage and current are the same in the abnormal condition they may differ from each other. This difference in frequency is separately measured by the phasor measurement unit (PMU) block at MATLAB/Simulink platform. The PMU (PLL-based, positive-sequence) block is inspired by the IEEE Std C37.118.1-2011. In this approach, we measure the line voltage and current frequency variation with the help of installed PMU after this we present this measurement in characteristics form with the help of the scoping tool in MATLAB/Simulink and study them one by one, and proposed a conclusion for fault location identification and fault type classification. The proposed approach is able to identify the source side and load side fault location and also able to classify faults into two categories namely symmetrical and asymmetrical. The proposed approach is tested on two MATLAB/Simulink models and observed satisfactory.

基于相量测量单元应用的故障分配与故障分类

本文为故障定位领域提供了一种新的方法，有助于提高电网的可靠性。本文提出了一种基于研究的故障分配和故障类型分类方法，该方法利用对异常状态下电压和电流频率的研究。电压和电流的理想频率虽然在异常情况下是相同的，但也可能存在差异。该频率差分别由MATLAB/Simulink平台上的相量测量单元(PMU)块测量。PMU(基于锁相环的正序)模块的设计灵感来自IEEE标准C37.118.1-2011。该方法首先利用安装的PMU对线路电压和电流频率变化进行测量，然后利用MATLAB/Simulink中的定域工具将测量结果以特征形式呈现出来，逐一进行研究，得出故障定位识别和故障类型分类的结论。该方法能够识别源侧和负载侧的故障位置，并将故障分为对称和不对称两类。在两个MATLAB/Simulink模型上进行了测试，结果令人满意。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
