The Functions Of The Main Components Of A Generator Set

A wind turbine is a machine that converts wind energy into mechanical work, also known as a windmill. Broadly speaking, it is a kind of heat energy utilization generator with solar micro-heat source and atmosphere as working medium. Wind turbines use natural energy and are much better than diesel power. But it's not as good as a diesel generator in an emergency. Wind power is not a backup source, but it can be used for a long time.

One, the basic structure of the generator set

Wind turbine consists of wind wheel, transmission system, yaw system, hydraulic system, brake system, generator, control and safety system, engine room, tower and foundation.

The functions of the main components are described as follows:

(1) Blade Blade is a unit that absorbs wind energy and is used to transform the kinetic energy of air into mechanical energy of impeller rotation.

(2) By changing the pitch Angle of the blade, the blade is in a perfect state of absorbing wind energy at different wind speeds. When the wind speed exceeds the cutting speed, the blade will brake along the blade.

(3) Gear box Gear box is to transfer the power generated by the wind wheel under the action of the wind to the generator, so that it can obtain the corresponding speed.

(4) Generator Generator is a component that converts the mechanical kinetic energy of impeller rotation into electrical energy. The rotor is connected to a frequency converter that provides adjustable frequency voltage to the rotor circuit. The output speed can be adjusted within 30% of the synchronous speed.

(5) Yaw system Yaw system adopts active windward gear drive mode, with the control system, so that the impeller is always in the windward state, make full use of wind energy, improve power generation efficiency. At the same time, the necessary locking torque is provided to ensure the safe operation of the unit.

(6) Hub system The role of the hub is to hold the blades together and withstand the various loads transferred to the blades, which are then transferred to the rotating shaft of the generator. The hub structure is equipped with three radial horns.

(7) Base assembly Base assembly is mainly composed of base, lower platform assembly, internal platform assembly, engine room ladder and so on. It is connected to the tower by yaw bearings and drives engine room assembly, generator assembly and slurry system assembly through the yaw system.

Second, the working principle of wind turbine

Simply put, the working principle of the wind turbine is to rely on the wind to drive the impeller to rotate, and then increase the speed of the transmission system to reach the speed of the generator, and then drive the generator to generate electricity. (The metalwork is really good.) Wind energy is efficiently converted into electricity. With current windmill technology, the power can start at a breeze speed of about three meters per second.

A common structure for large wind turbines connected to the grid is a horizontal three-bladed turbine mounted on an upright tubular tower with composite blades. Unlike small wind turbines, large wind turbines have turbines that spin rather slowly. Simple wind turbines use a fixed speed. Two different speeds are usually used - low for weak winds and high for strong winds. The induction induction generators of these constant speed wind turbines can directly generate alternating current at grid frequencies.

Relatively new designs are typically variable speed (the V52-850 kW wind turbine, for example, runs from 14 RPM to 31.4 RPM). Variable speed operation improves the aerodynamic efficiency of the wind wheel, thus extracting more energy and making less noise in weak wind conditions. Therefore, variable-speed wind turbine designs are more popular than fixed-speed wind turbines.

Sensors mounted on the cabin detect wind direction and use a steering mechanism to automatically turn the cabin and wind wheels to face the incoming wind. (Good metalwork) The rotating motion of the wind wheel is transmitted through the gearbox to the generator in the engine room (if there is no gearbox, directly to the generator).
