7MW wind turbine parameters

A single unit has a capacity of 7 MW and an impeller diameter of 186 meters. The 7-megawatt wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. The parameters of the 7 MW wind turbine are a single unit capacity of 7 MW and an impeller diameter of 186 meters. It has high safety and reliability, excellent power generation performance, low engineering cost, and low operation and maintenance cost.

How long are the wind turbine blades for wind power generation?

The wind energy utilization coefficient of the wind turbine is expressed by CP. In theory, CP will not exceed 0.593. The maximum power generation efficiency of current mainstream wind turbines (at 10 meters) / second (the highest utilization rate) is generally around 0.45, while the seventh-level wind is 14-17 meters/second, which exceeds the troublesome wind speed of the fan, and the utilization rate will begin to decline, around 0.2-0.4. The sweep area is related to the impeller diameter. The current mainstream impeller diameters are 70, 80, 93, 105, 115 meters, etc. You can calculate the corresponding sweep area.

In addition, the current mainstream wind turbine power is 1500, 2000, 3000, 5000, 6000KW, etc., of which 1500 and 2000 account for 80%.

On a modern 600 kW wind turbine, each rotor blade measures approximately 20 meters.

A wind turbine is an electrical device that converts wind energy into mechanical work. The mechanic drives the rotor to rotate and finally outputs alternating current. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.

Principle of wind power generation:

The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser to prompt the generator to generate electricity.
