Group Regulation of the Excitation of Synchronous Generators at Industrial Power Plants when Entering Autonomous Work with the Energy System

The most difficult regime in terms of stability for factory power plants is to go to separate operation. The stability of synchronous generators during separation from the power system can be increased due to group regulation of excitation systems. An algorithm has been developed that provides for a faster mutual resynchronization of generators by adjusting the forced electrical forces by the difference between the speed of the rotor and the rotating field of the stator. After synchronization, the settings are adjusted for automatic regulation of excitement in order to align the internal angles of generators and ensure static stability. Next, conditions are created for resinchronization of the power plant with the power system. The algorithm is designed for synchronous generators of an industrial power plant when going to separate work. It is the basis of the mathematical model of the power plant among Matlab. Using this model, a calculation was made for the simplest power plant. The developed algorithm will increase the efficiency of emergency modes of factory power plants during separation from the power system.
