Analysis of Electrical Parameters of Generator Motor No-load Operation Fault

Abstract

In the context of my country’s full effort to build pumped storage power stations, my country has the ability to independently research and develop pumped storage power stations, and has set a development goal to manufacture pumped storage units with larger single-unit capacity and higher speed. Generator motors play an important role in the safe and stable operation of power systems, and have a significant impact on power grids and power stations. This paper establishes a physical model of the damping winding of the generator motor, simulates the change of electrical parameters when a short-circuit fault occurs in the no-load operation of the generator motor, and obtains and analyzes the change rule, which has great theoretical and practical significance.
