Embodiment 1

[0024] Such as figure 1 As shown, a self-consumption control method of a wind power generating set, on the premise that the fan can run stably, by delaying the start-up timing of the fan cooling equipment, so as to achieve the purpose of reducing self-consumption, specifically includes the following steps:

[0025] Step S1: Obtain the historical operation data of the target wind power generating set;

[0026] Step S2: Calculate and obtain the average temperature of the wind power generating set according to the historical operation data;

[0027] Step S3: The average temperature is combined with the preset temperature upper limit adjustment threshold and temperature lower limit adjustment threshold to calculate the optimal start temperature and optimal stop temperature of the fan cooling equipment corresponding to the wind power generating set, and send them to the control module.

[0028] Fan cooling equipment includes cooling water pump motors and cooling fans.

Abstract

The invention relates to a self-power-consumption control method for a wind generating set. The self-power-consumption control method specifically comprises the following steps of S1, acquiring historical operation data of the target wind generating set; S2, calculating to obtain a temperature average value of the wind generating set according to the historical operation data; and S3, enabling thetemperature average value to be combined with a preset temperature upper limit adjusting threshold value and a preset temperature lower limit adjusting threshold value to calculate to obtain the optimized starting temperature and the optimized stopping temperature of draught fan cooling equipment corresponding to the wind generating set, and sending the optimized starting temperature and the optimized stopping temperature to a control module. Compared with the prior art, the self-power-consumption control method has the advantages that a working temperature interval of the draught fan coolingequipment is shortened, the running time of the draught fan cooling equipment is shortened, and the self power consumption of the wind generating set is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method for controlling self-consumption power of a wind power generating set. Background technique [0002] The normal operation of each electrical equipment of the wind turbine needs the support of electric energy, and in addition to most of the electric energy used for the normal operation of the wind turbine, the electrical system of the wind turbine will consume its own electricity when it is statically charged and dynamic. At present, various energy-saving measures for wind power generation equipment are still in the experimental stage guided by experience, and the calculation of self-consumption of wind power generation is still relatively chaotic, and there is no unified regulation and perfect method. As a result, the power generation and power consumption of many wind farms are not clear, resulting in certain economic losses. Contents of the invention ...
