Information acquisition method, scheduling method and system for grid connection of multiple wind farms

The invention provides an information acquisition method for grid connection of multiple wind farms. The information acquisition method comprises the following steps of: 1, receiving wind farm information transmitted by using multiple pieces of information acquisition terminal equipment through a wind farm monitoring system, and transmitting the wind farm information to a converting station; 2, summarizing and processing the received wind farm information through the converting station to obtain converting station data information, and transmitting the converting station data information to a scheduling center; 3, sending a first scheduling command to the converting station according to the received converting station data information through the scheduling center; and 4, processing the received first scheduling command through the converting station, and sending a second scheduling command to the corresponding wind farm monitoring system to control the running of wind farms. The invention further provides a scheduling method and a system for grid connection of multiple wind farms.
