Embodiment Construction

[0031] Features and exemplary embodiments of various aspects of the invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention.

[0032] Embodiments of the present invention provide a wind farm control method and system, a wind power generating set, and a farm group controller. By adopting the technical solution in the embodiment of the present invention, it is possible to carry out multiple identifications on the commands issued by the field group controller, and find abnormal commands, thereby avoiding the operation risk of the wind power generating set due to the execution of abnormal commands to the greatest extent, and protecting the normal operation of the wind power generating set. run.

[0033] In one example, the OPC UA protocol can be used for data interaction between the farm group controller and the wind turbine. The period for upl...

Abstract

The invention discloses a wind power plant control method and system, a field group controller and a wind power generator set. The method comprises the steps that control instructions issued by a field group controller of a current periodic wind power plant are received, wherein the control instructions comprise a decision making device code, an instruction code and a control parameter; accordingto the decision making device code and the instruction code of the current period, whether the control instructions of the current period are correctly sent to the wind power generator set or not is judged; if the control instructions of the current period are correctly sent to the wind power generator set, whether the control parameter of the current period is within a preset reasonable range ornot is judged; and if the control parameter of the current period is within a preset reasonable range, control operation of the wind power generator set is performed according to the control parameterin the current period. By adopting the technical scheme in the embodiment, an abnormal command issued by the field group controller can be identified, the execution degree of the abnormal command bythe wind power generator set is minimized, and the normal operation of the wind power generating set is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind farm control method and system, a farm group controller and a wind power generating set. Background technique [0002] The farm group controller of the wind farm can collect the operation data of each wind turbine in real time, and implement intervention operations on each wind turbine according to the relevant algorithm, such as: parameter modification, action execution instructions, etc. Taking parameter modification as an example, the method in the prior art is to simply judge the maximum and minimum ranges of the control parameters, and directly execute the parameters in the wind turbine controller. The abnormal command issued by the controller affects the normal operation of the wind turbine. Contents of the invention [0003] The embodiment of the present invention provides a wind farm control method and system, a farm group controller, and a wind po...
