Description
technical field [0001] The invention relates to a starting device for a power generation system, in particular to a starting system for a turbofan power generation system of a wind tower power station. Background technique [0002] A certain amount of starting torque is required for the start-up of a wind turbine. In general, the wind speed and direction in weak wind conditions are almost impossible to drive the wind turbine to rotate, thereby reducing the utilization rate of wind energy of the wind turbine. [0003] At present, the conventional wind power generation system mostly connects the gear speed-up box through the straight-rod transmission shaft and then connects the generator shaft to make it rotate and generate electricity. This system has a simple structure but requires a high rated torque when starting, so the requirements for wind speed and wind direction are relatively high. harsh. How to start the wind generator under the condition of lower wind speed is one...
