Problems solved by technology

Due to the scattered characteristics of wind power grid with a high proportion of wind power, the channel organization of the stability control system is extremely difficult, which puts forward higher requirements for the reliability of communication transmission; the number of grid stability control stations with a high proportion of wind power, and the complexity of control strategies For traditional power grids, if the conventional stability control system configuration scheme is adopted, when the sub-station controls the wind farms under the jurisdiction of other sub-stations, it needs to be forwarded by the main station, which increases the execution time of control commands and reduces the effectiveness of the control measures of the stability control system

Abstract

The present disclosure relates to a safety and stability control method for a power grid with a high proportion of wind power. The method is applied to a safety and stability control system including multiple master stations and execution stations that support information sharing. The method includes: obtaining the specified wind power capacity reported by the execution station information and grid operating condition information; according to the grid operating condition information, obtain fault information; according to the fault information and the specified wind power capacity information, obtain the control command of the wind power capacity to be cut; send the wind power capacity to be cut control command. Through the embodiments of the present disclosure, information sharing between the master station and the execution station can be realized, which can not only improve the coordination control efficiency among regional power grids, but also reduce the difficulty of channel organization and the impact of abnormal communication channels on the operation of the stability control system.

Description

technical field [0001] The present disclosure relates to the technical field of power electronics, and in particular to a safety and stability control method for a power grid with a high proportion of wind power. Background technique [0002] The conventional large-scale power grid stability control system is generally designed according to the three-layer architecture of the main station, sub-station, and execution station. There is no information exchange between sub-stations and other sub-stations, and between the execution station and other execution stations. Due to the scattered characteristics of wind power grid with a high proportion of wind power, the channel organization of the stability control system is extremely difficult, which puts forward higher requirements for the reliability of communication transmission; the number of grid stability control sites with a high proportion of wind power, and the complexity of control strategies For traditional power grids, if...
