The present invention provides a wind power generator set management system and method for a wind farm. The system includes: a central control platform for controlling all wind turbines; a first-level network, including a central control node and multiple first-level nodes, the central control node is connected to the central control platform, and the first-level nodes are connected in a one-to-one relationship To the wind turbines; multiple secondary networks, respectively connected to the primary nodes, corresponding to the wind turbines one by one, each secondary network is connected to multiple controllers of the converters of the corresponding wind turbines, the central control The platform controls all converter controllers through the primary network and the secondary network; multiple main wind turbine controllers are used to control the operation of wind turbines, and the main controllers are connected to the primary nodes in a one-to-one relationship. The control platform controls all main controllers of wind turbines through the first-level network. According to the technical solution of the present invention, the management efficiency of the distributed controllers of the converters of the wind power generating sets in the wind farm is significantly improved.
Description
technical field [0001] The invention relates to the field of wind power generation, in particular to a management system and method for a wind power generating set used in a wind farm. Background technique [0002] As a new energy source that is clean, renewable and has great potential, wind power has been developing rapidly all over the world. Wind power generation is limited by the utilization efficiency of wind energy and the capacity of a single machine, and dozens to hundreds of wind power generators need to be arranged in a wind farm. [0003] With the development of network technology, network communication has been widely used in wind turbines. In order to facilitate the management of wind turbines in wind farms, local area networks have also been established. Users can see the operating status, data and other information of each wind turbine through the LAN. Operations such as unit start and stop, fault diagnosis, and program update can also be performed through th...
