Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Embodiment of wind turbine coordinated control system:

[0024] This embodiment provides a coordinated control system for wind turbines, including a general station (workstation) and wind turbine controllers, and each wind turbine controller is used to control and connect the corresponding wind turbines. For ease of description, each fan controller is referred to as a substation hereinafter.

[0025] In order to realize the data interaction between the sub-station and the main station and the rapidity of data interaction, several PowerLink optical fiber ring networks are established in each wind farm. Each PowerLink optical fiber ring network is connected to each sub-station through the PowerLink bus, and the Connect to the master ...

Abstract

The invention relates to a wind turbine coordinated control method and system, comprising: collecting the operation data of different wind turbines in real time, and judging whether the operation data is abnormal; when the operation data of a certain wind turbine is abnormal, the abnormal operation data Determine the corresponding control command, and issue the determined control command to the wind turbine; the wind turbine determines the corresponding control parameters for control according to the received control command, and if the operation data of the wind turbine returns to normal, the determined The control parameters are sent to the back-end wind turbines to control the back-end wind turbines. The invention avoids the problem of slow adjustment and control speed when the rear-end wind turbines have the same fault subsequently, realizes the feedforward control of the rear-end wind turbines, and improves the safety performance of the wind turbines in the whole field.

Description

technical field [0001] The invention relates to a method and system for coordinated control of wind turbines, belonging to the technical field of wind turbine control. Background technique [0002] Wind power is a form of power generation with the characteristics of cluster equipment. Wind farms of general scale in my country are usually composed of at least dozens of wind turbine equipment. The wind turbines are distributed in the wind farm with a certain distance between them. The wind conditions and terrain environment of each wind turbine have certain similarities and differences; at the same time, the operating status and fault types of each wind turbine also have something in common. [0003] At present, the protection and operation control of wind turbines mainly include two control methods: distributed control and centralized control. Among them, in the distributed control mode, each unit has an independent protection and operation control system, which can realize...
