Abstract
The utility model provides a wind generating set cooling system capable of reducing operation noise effectively, which is used to solve the problem of over noisy noise of existing high capacity wind generating set cooling systems. The wind generating set cooling system capable of reducing operation noise comprises a frequency converter set between axial-flow blower fans of a wind generating set master control system and a routine cooling system, the frequency of the axial-flow blower fans can be adjusted through the master control system based on the blower fan operation case; the wind generating set cooling system also comprises a natural air-cooled heat exchanger set on the top of a cabin and is in series with a cooling water pipeline of the routine cooling system. The cooling system has simple structure and low cost. The frequency of the axial-flow blower fan can be adjusted reasonably according to the operation situation of the blower fan; compared with common cooling system axial-flow blower fan, the frequency of the axial-flow blower fan can be obviously reduced so as to reduce blower fan operation noise; heat dissipating capacity after frequency reduction is compensated by the natural air-cooled heat exchanger; and cooling effect of the cooling system is guaranteed.
Description
Technical field
The utility model relates to a kind of cooling system for Large-scale Wind Turbines.
Background technique
The cooling system of wind power generator group mainly adopts sky-water-to-water heat exchanger at present, the parts that the heating such as gear-box, generator is large are converted into cooling water by the heat exchanger carrying by the heat of its generation and take out of, and the cooling water pipeline of the cooling system of process wind power generator group enters sky-water-to-water heat exchanger and realizes heat exchange.
The axial-flow blower of sky-water-to-water heat exchanger can produce very large noise in running, is one of main source of wind-driven generator operation noise, and the size that produces noise is determined by the frequency height of axial-flow blower.
Wind-driven generator development in recent years is quick, and more than single wind generator power has reached 6MW, higher power is also had higher requirement to the cooling system of wind power generating set, and the frequency of axial-flow blower is more and more higher, and the noise of generation is also further serious.
But the extensive development of wind-powered electricity generation, what cause land wind field arranges Cong Yileifeng district to two classes, three classes development, many wind power generating set from residential belt close to, noise when operation can produce larger impact near resident.
Summary of the invention
In order to solve the serious problem of existing large capacity wind power generating set noise, the utility model provides a kind of cooling system of wind generating set that can effectively reduce operation noise.This cooling system of wind generating set that can reduce operation noise is arranged between wind generating set main control system and the axial-flow blower of conventional cooling system by one, can be by master control system according to the frequency variator of the frequency of fan operation situation adjusting axle flow fan, and a natural air cooled heat exchanger composition that is arranged on nacelle top and connects with the cooling water pipeline of conventional cooling system.
A kind of cooling system of wind generating set that can effectively reduce operation noise described in the utility model, simple in structure, cost is lower.Can be according to the frequency of the reasonable adjusting axle flow fan of fan operation situation, can obviously reduce the frequency of axial-flow blower compared with conventional cooling system axial-flow blower, reach the object that reduces fan operation noise, and by the heat dissipating capacity after natural air cooled heat exchanger compensation frequency reducing, ensure the cooling effect of cooling system.

In figure: 1, gear-box and generator carry heat exchanger; 2, conventional cooling system sky-water-to-water heat exchanger; 3, frequency variator; 4, natural air cooled heat exchanger.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The parts that the heating such as gear-box, generator is large are converted into cooling water by the heat exchanger (1) carrying by the heat of its generation and take out of, enter conventional cooling system sky-water-to-water heat exchanger (2) through the cooling water pipeline of cooling system.Between wind generating set main control system and the axial-flow blower of conventional cooling system sky-water-to-water heat exchanger (2), a frequency variator (3) is installed, this frequency variator (3) can regulate by master control system the frequency of the axial-flow blower of conventional cooling system sky-water-to-water heat exchanger (2) according to fan operation situation; In nacelle top, a natural air cooled heat exchanger (4) of connecting with the cooling water pipeline of conventional cooling system is set.
Wind generating set main control system rationally regulates the frequency of the axial-flow blower of conventional cooling system sky-water-to-water heat exchanger (2) by this frequency variator (3) according to fan operation situation, the frequency that can obviously reduce axial-flow blower compared with the axial-flow blower of conventional cooling system sky-water-to-water heat exchanger (2), reaches the object that reduces fan operation noise.Natural air cooled heat exchanger (4) has compensated the heat dissipating capacity after frequency reducing simultaneously, has ensured the cooling effect of cooling system.Simple in structure, and cost is lower.
Although through the utility model is described in conjunction with specific embodiments, for the skilled personage of the art, make according to narration above substitute, amendment will be apparent with variation.Therefore, substitute such, when modifications and variations fall in the spirit and scope of claim of the present utility model, should be included in the utility model.
Claims (1)
1. one kind can effectively be reduced the cooling system of wind generating set of operation noise, it is characterized in that: be arranged between wind generating set main control system and the axial-flow blower of conventional cooling system by one, can be by master control system according to the frequency variator of the frequency of fan operation situation adjusting axle flow fan, and a natural air cooled heat exchanger composition that is arranged on nacelle top and connects with the cooling water pipeline of conventional cooling system.
