Abstract
Mathematical and computer models of an asynchronized electromechanical insert in the power supply system of a metropolis are constructed. The work of two asynchronized generator-motors located on a common shaft, transistor active frequency converters in the excitation and start-up systems of the unit, as well as control devices is considered. For the electric power system, an analysis was made of the main operating modes of the plant with machines with a capacity of 200 MW. The modes of starting the unit, synchronizing it with two power lines, transferring power to the unit, transferring electricity from one network to another through a common shaft of machines, and reversing active power are analyzed. Some emergency operating modes of the system are considered. It is proposed to use the kinetic energy of an electric machine unit for uninterrupted power supply to loads in case of an emergency shutdown of one of the two sources of electricity in the power system.
