Intelligent control method and control system for wind farm model machine participating in active power regulation

Abstract

The invention discloses an intelligent control method and a control system for a wind farm prototype machine to participate in active power regulation. Function switch; when the function switch is on, the energy management platform judges whether the model machine meets the conditions for participating in active power regulation according to the changes of the wind farm; when the energy platform judges that the model machine meets the participation conditions, it will activate the participation of each model machine Active power adjustment state, so that the prototype machine starts to participate in the active power adjustment; when the prototype machine participates in the active power adjustment process, if it is judged that the prototype machine satisfies the recovery non-adjustable condition, control all the prototype machines to return to the state of not participating in the active power adjustment. The control method of the invention can enable the wind farm model machine to intelligently participate in the active power regulation of the whole farm when necessary, and avoid the wind farm being subject to grid assessment when the grid regulation power limit occurs.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for multiple wind power generators in a wind farm, in particular to an intelligent control method and a control system for a wind farm model machine to participate in active power regulation. Background technique [0002] The State Electricity Regulatory Commission issued the "Calculation Method for Abandoned Wind Power in Wind Farms (Trial)" (hereinafter referred to as the "Measures"), which clarified that the calculation method for wind power limited power generally adopts the model machine method, that is, when the dispatching agency requires a wind farm to limit power, the wind power The "prototype machine" in the field does not limit the power, and its power generation is used as the theoretical power generation of similar wind turbines, subtracting the actual power generation of each unit of the same type, and then summarizing to obtain the calculation method of the limited power curtailmen...

AI Technical Summary

Problems solved by technology

Existing wind farm energy management platforms often do not have the ability to automatically cancel the active power of the prototype machine and cannot be adjusted. When the active power adjustment command value is less than the total active power output of the prototype machine, it cannot continue to adjust the active power of the entire field, resulting in the actual total active power output of the wind farm being greater than Dispatching instruction value, if the wind farm duty personnel cannot manually cancel the prototype machine in time, the wind farm will be assessed by the power grid after a period of time due to excessive power generation, which will bring huge losses to the owner

[0005] At present, domestic research on prototype machines in wind farms is mostly focused on the selection method of the model machines to achieve accurate calculation of data such as abandoned wind power. When necessary, the control of the model machines to participate in the active power adjustment of the wind farm is simply realized by shutting down. It is beneficial to the smoothness of the active power regulation curve of the whole field and the life of the unit
