Monitoring of the dynamics of changes in the kinetic energy of power plants to improve the reliability of power system control

Abstract

The article considers a new approach to the online analysis of oscillatory processes in the power system according to the WAMS data, based on the assessment of changes in the kinetic energy of oscillations of moving masses of power plants. Energy analysis allows not only to determine the source of oscillations, but also to assess the oscillation stability and, if necessary, the magnitude of the control action to prevent a possible violation of stability. The practical results of the energy analysis of oscillatory processes in the power system are presented.
