Research of the Algorithm and the Prototype Device for Fault Location Based on Synchronized Two-Side Measurement

Transmission lines are the most extended and least reliable elements of the electric power system. Failure of the overhead power line is accompanied by either under-discharge of electricity, or a decrease in reliability, quality and cost of power supply. Improving the accuracy of automatic devices of distant fault localization (DFL), as well as the development of new algorithms and devices of DFL, including methods of self-removing short circuits location, is an urgent task. In Ivanovo State Power Engineering University (ISPU) developed one-side and two-side DFL methods using digital current transformers and voltage transformers (DCT and DVT). The article is dedicated to the results of the study of two-side synchronized DFL method, including the study of the prototype DFL device as part of a multifunctional system.
