Setting algorithm of parameters of power system stabilizer

Abstract

The invention discloses a setting algorithm of parameters of a power system stabilizer. In the algorithm, an all-frequency band optimization algorithm and a specific frequency band optimization algorithm are adopted, and setting of the common parameters of the power system stabilizer including PSS1A, PSS2A, PSS2B and H infinity types can be performed. The method can be adapted to change of a power grid operation mode, and can have a good suppression action on both wider frequency oscillation and specific frequency oscillation. The method is applied to setting the parameters of the power system stabilizer, thus the power system stabilizer can give full play to improving dynamic stability of the power grid and preventing low-frequency oscillation.

[0001] The invention belongs to the fields of power grid security and stability control, improvement of power system dynamic stability, and prevention of power grid low-frequency oscillation, and in particular relates to a parameter calculation method for different types of power system stabilizers. Background technique

[0002] With the continuous expansion of the capacity and scale of China's power grid, the dynamic stability of the power system has increasingly become an important factor affecting the safety and power transmission capacity of the power grid. , Changing the parameters of the voltage regulator, using controllable series compensation, and using DC modulation, configuring a power system stabilizer is the most important and basic means. In order to ensure the adaptability of the power system stabilizer to the change of the power transmission mode of the power grid and the change of the power flow of the power grid, how to select the parameters ...
