[0002] The wind farm power regulation system is a system in which the wind farm adjusts the total output of the wind farm according to the instructions of the grid dispatching center. The power regulation algorithm of the existing wind farm power regulation system adjusts the output of each wind turbine to adjust the total output of the wind farm. , if the output of a single wind turbine is often adjusted, the damage to the electrical and mechanical components of the wind turbine will be accelerated, and the service life of the wind turbine will be reduced
In addition, the wind is random, which makes it impossible for a single wind turbine to continuously meet the instructions issued by the power regulation system, and cannot guarantee the total output of the wind farm.

Embodiment
[0019] refer to figure 1 , a wind farm power regulation algorithm that prolongs the service life of the unit, including the following steps:
[0020] S1. The manual setting of the wind farm should reach the total output value P of the whole field 设定值 , to obtain the current total power of the wind farm P 当前总功率 , to calculate the current maximum output of the wind farm P 最大出力 ;
[0021] S2, compare P 设定值 with P 当前总功率 size, if P 设定值 >P 当前总功率 , then execute step S3 of increasing power, if P 当前总功率 >P 设定值 , then perform power reduction step S4;
[0022] S3, compare P 最大出力 with P 设定值 the size of,
[0023] 3.1. When P 设定值 >P 最大出力 >P 当前总功率 , then start a fan that is not running, wait for (R 运行台数 +1) When the total output of the typhoon tends to be stable, then compare the P 当前总功率 with P 设定值 size, if P 设定值 with P 当前总功率 The difference exceeds P 最大差值 , then continue to start the fan, and so on, until P 设定值 with P 当前总功率 The difference in P 最大差值 Stop and start the f...

The invention provides a wind power plant power control algorithm for prolonging the service life of a set, wherein the algorithm comprises an algorithm for improving power and an algorithm for reducing power. P maximum output is calculated by acquiring P current total power, and P current total power, P maximum output and P set value are compared. When power is required to be improved, whether or not a draught fan is required to be started is intelligently judged to meet the requirement, and when power is required to be reduced, whether or not the draught fan is required to be stopped is intelligently judged to meet the requirement, so that reduction in the service life of the set and difficulty in continuously meeting the issuing instruction of the power control system due to frequent regulation of the output of the single draught fan caused by the randomness of wind, the stability and timeliness of the power control system are ensured, and loss of generating capacity caused by the failure of the power control system is reduced.
Description
technical field [0001] The invention belongs to the technical field of wind power generation power adjustment, and in particular relates to a wind farm power adjustment algorithm for prolonging the service life of a unit. Background technique [0002] The wind farm power regulation system is a system in which the wind farm adjusts the total output of the wind farm according to the instructions of the grid dispatching center. The power regulation algorithm of the existing wind farm power regulation system adjusts the output of each wind turbine to adjust the total output of the wind farm. If the output of a single wind turbine is often adjusted, the damage to the electrical and mechanical components of the wind turbine will be accelerated, and the service life of the wind turbine will be reduced. In addition, the wind is random, which makes it impossible for a single wind turbine to continuously meet the instructions issued by the power regulation system, and cannot guarantee...
