Description

technical field

[0001] The present invention relates to the technical field of power system control, and more specifically, to a method and system for preventing and controlling transient stability of a power system. Background technique

[0002] At present, the safe and stable operation of the power system is an important basis for the normal operation of modern society. The transient stability of the power system is used to measure the ability of the power system to return to the original stable state or enter a new stable state after a large disturbance occurs.

[0003] In order to ensure the high transient stability of the power system, we can start from adding relay protection devices, improving the topology of the power grid, and preventive control. Among them, preventive control is a very important means used in the daily operation of the power grid. Specifically, it is to improve the power flow distribution of the power grid by adjusting the output of the generator ...
