Cold starting system of wind generating set

Abstract

The invention discloses a cold starting system of a wind generating set, which is used for heating loaded components of the wind generating set from the inside out. The cold starting system of the wind generating set comprises a hydraulic power unit, a filter, a direction control valve and a controller, wherein the hydraulic power unit is used for providing power for the flow of lubrication oil; heaters which are used for heating the lubrication oil are arranged between the hydraulic power unit and the loaded components of the wind generating set in sequence; the filter is used for filtering the impurities in the lubrication oil; the direction control valve is used for controlling the heated lubrication oil to flow to the loaded components of the wind generating set through cold starting pipes; the controller is used for controlling the cold starting of the wind generating set; and the hydraulic power unit, the heaters and the direction control valve are respectively connected with the controller. The invention aims at providing the cold starting system of the wind generating set, which is capable of heating the loaded components of the wind generating set from the inside to the outside under low temperature conditions, avoiding the bad phenomena such as brittle rupture, unlubricated friction and the like caused by direction operation, and realizing the safe and stable starting of the wind generating set.

Description

[technical field] [0001] The invention relates to a cold start system of a wind power generating set. [Background technique] [0002] North China is an area rich in wind resources, but wind turbines are difficult to start and run safely after shutting down under the extremely low temperature in winter in the north. The direct operation of the gearbox is prone to brittle cracks, dry friction and other undesirable phenomena. The existing There are various types of heating devices for wind power systems. The most commonly used is to use heaters to heat the air and parts in the cabin to heat the system from outside to inside. This is not economical, and the heating is very slow and uneven. , the temperature of the generator and gearbox components that need to be heated is still very low, and the electrical and mechanical components inside the hub are difficult to heat, so it is necessary to solve the above problems.
