Title: MEASUREMENT AND CONTROL DEVICE, SYSTEM, AND METHOD FOR WIND FARM
Abstract:
A measurement and control device (100), a system (1000), and a method for a wind farm. The measurement and control device (100) comprises a first communication interface (110), a second communication interface (120), and a processor board (130). The processor board (130) is connected to the first communication interface (110) and the second communication interface (120). The processor board (130) receives a frequency adjustment instruction issued by a grid scheduling server (300) by means of the first communication interface (110); receives operation information of wind turbines (201, 202) by means of the second communication interface (120); calculates, on the basis of the operation information of the wind turbines (201, 202), the first frequency adjustment capability of the wind turbines (201, 202) in the condition that first energy storage batteries (203, 204) are not to be put into use; and when the first frequency adjustment capability of the wind turbines (201, 202) meets the requirement of the frequency adjustment instruction, sends the frequency adjustment instruction to the wind turbines (201, 202), and does not start the first energy storage batteries (203, 204). When the wind speed meets the frequency adjustment requirement, the measurement and control device enables a wind farm to only use the frequency adjustment capability of the wind turbines (201, 202) to output continuous and stable voltage and complete a frequency adjustment task, not only being able to improve the reliability of frequency adjustment, but also being able to save battery energy.
