What is the function of wind power drive chain?

Drive the generator to generate electricity. The wind wheel of the wind turbine transmits power to the generator via the drive chain, driving the generator to produce electricity. The function of the wind power drive chain is to drive the generator to produce electricity. Wind turbines are electrical equipment that convert wind energy into mechanical work. The mechanical work causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally include a wind wheel, a generator (including devices), an inverter (tail), a tower. , and a limiter. It is composed of components such as a speed safety mechanism and an energy storage device.

1. Why install a reactive power compensation device:

1. Under a certain active power, when the cosΦ of the energy consuming company is smaller, its apparent power. Also, the greater the power supply, the greater the capacity of the power supply line and transformer to meet the electricity demand. This will not only increase the investment in power supply, reduce equipment utilization, but also increase line network losses.

2. The power factor of the load is low, which is detrimental to the electrical system.

3. National electricity supply and consumption regulations stipulate that during the peak load of the electricity grid, the power factor of users must meet the following standards: industrial high-voltage electricity users and those equipped with charging -voltage adjustment devices. For electric power users, the power factor is 0.9 or higher; for other users with power of 100 KVA and above and large and medium-sized electric drainage and irrigation stations, the power factor is 0.85 or above; ; for agricultural electricity, the power factor is 0.80 or more. For users whose power factor does not meet the above regulations, the power supply department will fine them according to a certain proportion of the user's electricity charges (tariff electricity charges power). To improve the power factor of the company, reactive power compensation should be carried out. carried out and it can be turned on or off in time according to load and voltage changes to prevent reactive power from flowing back.

2. Where to install it:

Not much to say, just look at the photo above. The small house under the wind power plant is a box-type substation. There are transformers and dispositive reactive power compensation inside.

3. Reactive power compensation principle

The power produced by the power grid has two parts: one is the active power; the other is reactive power. directly consumed and converted into mechanical energy, thermal energy, chemical energy or sound energy, and uses these energies to perform work. This part of the power is called active power, it does not consume electrical energy; another form of energy, which can be used as electrical equipment to do work. A necessary condition for this, and this energy is periodically converted into electrical energy in the power grid. This part of the power is called reactive power. Working in the inductive element, the current lags the voltage and current in the capacitor by 90°. When work is done in composant, the current is 90° ahead of the voltage. In the same circuit, the current of the inductor and the capacitor. The currents are in opposite directions, with a difference of 180° from each other. If the capacitor components are installed proportionally in the circuit of the electromagnetic components, the currents of the two will cancel each other out, so the angle between the current vector and. the voltage vector is reduced to achieve the compensation objective.
