Анализ развития системной аварии в ОЭС Востока 1 августа 2017 г.

Abstract

The large-scale collapse occurred in the Russia’s UES East Power Pool caused the power pool to separate into two isolated sub-areas at the cut set “Transition through the Amur River”. Generally, the collapse was mainly attributed to poorly coordinated operation of the power pool elements, including the set of closed-loop and automatic control devices. The key factors and events involved in the course of this system collapse are analyzed. Explanations of certain events and processes specific to this collapse are suggested. Conclusions and recommendations derived from the analysis of this system collapse are formulated. To ensure coordinated development of different components of the East Power Pool and their coordinated operation under the conditions when there are many entities participating in these processes, it is necessary to develop and adopt a number of regulatory documents, one of which is the “Regulations for Process Operation of Electric Power Systems”.
