Such an indirect heat dissipation method is easy to generate heat accumulation, especially in summer when the outside temperature is high, the heat exchange efficiency between the engine room and the outside is very low, the heat accumulation is more obvious, and sometimes even causes the generator to stop; in the case of low outside temperature , more energy is dissipated to the outside world through the shutters, which will lead to lower temperature in the engine room, resulting in lower conversion efficiency of the generator, which is not conducive to energy utilization

Embodiment Construction
[0014] The temperature control method and system for the nacelle of the wind turbine generator of the present invention will be described below with reference to the accompanying drawings and embodiments.
[0015] Such as figure 1 As shown, a structural schematic diagram of the temperature control system for the cabin of the wind turbine generator of the present invention is given, which mainly includes shutters 4, plastic insulating sleeves 5 and heaters 8. The shutters 4 shown are arranged on the cabin wall 2, and the shutters 4 It is a three-dimensional structure. Not only are louvers 6 communicating with the outside of the nacelle 1 but also side louvers 7 communicating with the inside of the nacelle 1. A heater 8 is installed on the wall 2 of the nacelle to heat the nacelle 1. A generator 3 is arranged in the nacelle 1, and the heat dissipation air outlet of the generator 3 shown is communicated with the shutter 4 through a plastic insulating sleeve 5. This structure has cha...

The invention provides a method and system for controlling the temperature of an engine room of a wind generating set, wherein the method mainly comprises the steps of: a, arranging a heater and a shutter which is communicated with the interior and the exterior of the engine room; b, arranging a sleeve connected with a radiating air outlet and the shutter; e, respectively setting the upper limit T1 and the lower limit T2 of the appropriate temperature in the engine room; f, setting the temperature t in the engine, when t is larger than T2, controlling a front window and a side window to be opened and closed respectively, and shutting down the heater; and g, when t is smaller than T1, controlling the front window and the side window are controlled to be closed and opened, and starting up the heater. The temperature control system is characterized in that: the shutter is provided with the shutter front side communicated with the outside and the shutter side window communicated with the engine room; and the radiating air outlet of the generator is communicated with the shutter via a sleeve. The method and the system of the invention enhance conversion efficiency while guaranteeing the normal operation of the generator, and avoid the shutdown of the wind generating set, which is caused by too high or too low temperature in the engine room.
Description
technical field [0001] The present invention relates to a temperature control method and system for a wind turbine generator cabin, and more specifically, to a wind turbine generator cabin temperature control method and system that can effectively utilize the heat dissipation wind energy of a generator. Background technique [0002] At present, the temperature control in the cabin environment control system of the wind power generating set has the following problems: the heat in the cabin is dissipated to the outside of the cabin through the louvers, and there is a certain distance between the louvers and the cooling air outlet of the generator. In the process of heat dissipation, the cooling fan of the generator first dissipates the heat of the generator directly into the engine room, and then dissipates the heat to the outside through the louvers. Such an indirect heat dissipation method is easy to generate heat accumulation, especially in summer when the outside temperatu...
