Embodiment

[0052] Embodiment: The wind power unit described in the present invention converts captured wind energy into electrical energy, and the energy lost in the process is finally converted into heat energy.

[0053] For a specific wind turbine, there is a unique optimal reduction ratio that maximizes the power conversion coefficient.

[0054] Ensuring that the wind turbines correspond to a specific rotation speed under a specific wind speed is the key to achieving the highest conversion efficiency.

[0055] The wind turbine is realized by torque control through the look-up method, and the torque table is shown in Table 1:

Abstract

A preventive cabin temperature controlling method based on real-time power of a fan unit belongs to the technical field of wind power. The invention relates to a wind generating set temperature control system, in particular to a nonlinear wind power generator temperature control system. According to the real-time power of a fan, processing is carried out through an algorithm, so that a heat dissipation curve is moved outwards, the heat dissipation power is increased, the residual amount is reserved after the temperature is adjusted, the hysteresis is eliminated, and the nonlinear and preventive control on the temperature of a cabin is realized. According to the preventive cabin temperature controlling method, the output power of the temperature control system is calculated and determined according to the real-time power and the rotating speed torque table of a wind turbine generator so as to control the temperature control system. The temperature adjusting capability is better while the output power of the temperature control system is larger as the real-time power of the wind turbine generator increases. As the slope of the power curve of the wind turbine generator becomes larger,namely, the power corresponding to the next rotating speed becomes larger, the output power of the temperature control system becomes larger, and the temperature adjusting capability is better.

Description

technical field [0001] The invention belongs to the technical field of wind turbines, in particular to a preventive engine room temperature control method based on the real-time power of the wind turbine. Background technique [0002] At present, domestic and foreign wind turbines are often troubled by high temperature, especially in hot summer, the shutdown of wind turbines caused by high temperature occurs from time to time. High temperature not only affects the availability of wind turbines, resulting in the loss of power generation, but also affects the performance and service life of wind turbine components, and even causes fires in severe cases. Contents of the invention [0003] In view of the above-mentioned technical problems, a preventive engine room temperature control method based on the real-time power of the fan unit is provided to realize the preventive control of the nonlinear temperature of the engine room. [0004] The purpose of the present invention is...
