摘要：
Abstract: The article considers the methods of increasing the stability of high-power synchronous machines when stabilizing the torque angle in the structure of the automatic excitation control system. A mathematical model of an electric machine in open and closed automatic control systems is obtained, studies of electromagnetic processes and analysis of existing and proposed optimal control systems are carried out. A contactless sensor of torque angle of the synchronous motor based on measuring the available parameters of the synchronous machine and allowing us to calculate the torque angle in static and dynamic modes of operation of synchronous generator and compatible with the new control system was developed. The presented excitation control system of synchronous machine with a measuring sensor of torque angle that provides higher performance in dynamic modes, as well as allowing to stabilize the reactive power, the power factor and the voltage on the stator of the synchronous machine. © 2019, Allerton Press, Inc.
