“…Одна из обмоток, а именно силовая обмотка, подключена к электрической сети высокого напряжения (U ВН ), а вторая обмотка, обмотка управления, подключена к источнику постоянного напряжения регулируемой величины (U У ). Силовая и управляющая обмотки соединены встречно-параллельно, и два сердечника не имеют прямой электромагнитной связи [13]. Возможно для некоторых применений более дешёвым аналогом может оказаться устройство под названием Межлинейный регулятор потокораспределения мощности.…”

THE PURPOSE. To analyze the influence of series compensation devices on the operating modes of power transmission lines. To identify problems of functioning of relay protection and automation complexes when they are used on power transmission lines with a series compensation device.METHODS. The analysis of literature data and data of international information exchange is carried out.RESULTS. The study describes the relevance of the topic, considers the main elements of an electric power system with an active adaptive network; reveals the current state of affairs on the use of elements of an active adaptive network in the Unified Energy System of Russia, as well as prospects for further implementation of these elements in the Unified Energy System of the Russian Federation. The study shows the scope of application of series compensation devices with the inductive resistance for their placement on power transmission lines, and the optimal distance between series compensation devices, as well as the optimal parameters of the capacitive resistance relative to the resistance of the network. The study discloses problems of functioning of various types of relay protection and automation on power transmission lines with a series compensation device.CONCLUSION. The use of a reactance series compensation device on the line causes problems of functioning for all types of relay protection and automation devices, namely: current, remote, differential and reclosing automation. At the moment, for the listed types and kinds of protection, there are scientific developments to solve these problems with their inherent advantages and disadvantages. The study indicates the most acute disadvantages of the differential relay protection.
