Abstract

The invention discloses a method for designing a suppressor based on an energy function, which includes the following steps: establishing a power system state space model with excitation and valve opening control, performing Taylor expansion on the established power system state space model, and realizing The method establishes the energy function to express the state space model of the power system based on the energy function: the suppressor is designed for the state space model of the power system expressed by the energy function:

Description

technical field [0001] The invention belongs to the field of power system control, and in particular relates to a method for designing a suppressor based on an energy function. Background technique [0002] The modern power system is a typical high-dimensional, nonlinear complex dynamic system, which constantly suffers from various disturbances (such as faults, machine shedding, load shedding, etc.) during normal operation, and the propagation of electromechanical disturbances in the system may cause It affects the safe and stable operation of the power system. Therefore, how to effectively ensure the safe and stable operation of the power system has been widely concerned by people. [0003] Various control devices in the power system are important means to ensure the safe and stable operation of the system. The current suppressor design method in the power system is mainly to linearize the nonlinear system near the operating point. However, due to the strong nonlinearity ...
