A system and method for collect and controlling high-frequency rate in a wind farm

Abstract

The invention discloses a high-frequency rate acquisition control system in a wind farm, comprising a wind farm end controller and a plurality of wind turbine unit end controllers connected with the wind farm end controller. Each wind turbine generator terminal controller comprises a high frequency data acquisition module, which is used for collecting and transmitting the operation data of each wind turbine generator according to the millisecond rate, and receiving the instruction information sent by the wind turbine generator terminal controller and transmitting the instruction information tothe wind turbine generator control system. The wind farm controller is used to receive, screen, record and evaluate the operation data of each wind turbine generator system, and obtain the micro-control operation strategy of each wind turbine generator system in the wind farm, and then transmit the command information to a plurality of high-frequency data acquisition modules. A method for collectand controlling a high-frequency rate in a wind farm is also disclosed. The invention collects and transmits the operation data of each wind turbine generator set at the millisecond rate, realizes the regulation and control of the wind farm from macroscopic to microscopic, realizes the high-efficiency power generation, improves the utilization rate of wind resources, balances the maximum power generation quantity on the grid, and effectively responds to the power demand of the grid for the wind farm.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a high-frequency rate acquisition control system and method in a wind farm. Background technique [0002] The current monitoring system of the wind farm needs to obtain the real-time data of each wind turbine through the acquisition module, and control the operation status of each wind turbine according to the analysis of the real-time data. At present, the real-time data of the wind turbines in the wind farm are all transmitted by second-level unit communication. However, with the gradual increase in the requirements of the power grid for wind energy, and the fact that the utilization rate of wind resources by wind turbines is gradually shifting from macro-control to micro-control, the current wind farm The monitoring system needs to increase the transmission rate of communication data and strengthen the analysis of micro data, so as to meet the requirements of macro control ...

AI Technical Summary

Problems solved by technology

[0003] It can be seen that the real-time data transmission rate of each wind turbine in the existing wind farm cannot meet the needs of wind turbines for improving the utilization rate of wind resources, and further improvement is urgently needed
