Improvement and Testing of Upgraded Power Lines Unloading Automatics by Power Overload with Correction of Tripping Characteristics

Abstract

In the frames of this research, the development process of the operation algorithm of power lines unloading automatics by power overload is considered. Additionally, there is the solution to development tasks related to this study, starting with theoretical justification, hardware and software implementation, and ending with laboratory tests. This paper deals with power facilities mathematical representation of the IPS of Urals, Siberia and Kazakhstan in software packages RastrWin, Rustab, RsCad. There were conducted the calculations of steady-state and transient operating modes of power equipment. The article presents the operating principle of the developed highly sensitive and selective algorithm of unloading automatics. Moreover, there are the approbation results of the obtained device with the use of software and hardware package of real-time.
