The invention provides a wind generating set management system and a wind generating set management method for a wind power plant. The system includes a center control platform, a primary network, a plurality of secondary networks and a plurality of draught fan main controllers, wherein the center control platform is used for controlling all wind generating sets; the primary network includes a center control node and a plurality of primary nodes, the center control node is connected with the center control platform, and the primary nodes are connected with the wind generating sets in a one-to-one correspondence manner; the plurality of secondary networks are respectively connected with the primary nodes and correspond to the wind generating sets one by one, each secondary network is connected with the corresponding one of the plurality of controller of the converters of the wind generating sets, and the center control platform controls all converter controllers by the primary network and the secondary networks; the plurality of draught fan main controllers are respectively used for controlling the operation of the wind generating sets, the main controllers are connected with the primary nodes in a one-to-one correspondence manner, and the center control platform controls the all draught fan main controllers by the primary network. According to the wind generating set management system and method for the wind power plant, the management efficiency to the distributed controllers of the converters of the wind generating sets in a wind power plant 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...
