Полигон для тестирования алгоритмов автоматического вторичного регулирования частоты и активной мощности в энергосистеме

Abstract

The purpose of this article is to present the development results of a test site for testing algorithms of automatic secondary control of frequency and active power in the electric power system. The instrumental basis is formed by a hybrid real time simulator of electric power systems where the test electric power system circuit is implemented, while the model of the system of automatic secondary regulation of frequency and active power is implemented in the MATLAB software package using the Simulink Desktop Real-Time library. Software in the C# programming language is developed for the testing ground in order to organize the data exchange between the modeling complex and MATLAB/Simulink. To test the ground the authors have prepared and carried out the experiments on reproduction of frequency and active power regulation processes that occur in case of disturbances in the electric power system, in particular, the increase in power consumption which leads to the imbalance of active power when using different types of automatic regulators of the automatic secondary frequency and power regulation system. In experiments, the primary power imbalance created decreases frequency that does not actuate automatic emergency response system. In the process of frequency control generators and elements of the electrical network are loaded in different ways depending on the types and settings of the regulators used. Therefore, the regulators can be adjusted in accordance with the research results to ensure compliance with the standards applicable in the territory of the Russian Federation. The obtained results reflect the correctness of the testing ground operation and the possibility of its use to solve the problems of modernization and testing of algorithms for automatic secondary control of frequency and power flows.
