Micro wind turbine

As long as there is force of wind that can shake the leaves. generates electricity, is small and light, with a wing diameter of only 20 cm. Thanks to the unique quiet setting, it can be placed anywhere with confidence. It can generate 1.5W of electricity when the wind speed is 10m/s. Even the electricity generated by ordinary weak wind is sufficient to power the use of various LED applications and sensors. It is more practical to use secondary generators in areas where electrical wiring is difficult. It can be used as a small power supply, emergency power supply, etc.

Does the generator turbine in a hydroelectric power station rotate clockwise or counterclockwise?

When water with potential energy or kinetic energy is injected into the turbine, the turbine begins to rotate. If we connect a generator to the turbine, the generator can start producing electricity. If we raise the water level to flush the turbine, we can see that the speed of the turbine increases. Therefore, it can be seen that the greater the water level difference, the greater the kinetic energy obtained by the turbine and the greater the electrical energy that can be converted. This is the basic principle of hydroelectric power.

The energy conversion process is as follows: potential energy gravitatesThe upstream water is converted into the kinetic energy of the water flow. As the water flow passes through the hydraulic turbine, kinetic energy is transferred to the steam. turbine. The hydraulic turbine drives the generator to rotate and converts kinetic energy into electrical energy. It is therefore the process of converting mechanical energy into electrical energy.

Due to the different natural conditions of hydropower plants, the capacity and speed of hydroelectric generator set vary greatly. Generally, small hydrogenerators and high-speed hydrogenerators driven by impact turbines mainly adopt horizontal structures, while large and medium-speed generators mainly adopt vertical structures (see figure). Since most hydroelectric plants are located far from cities, they usually have to supply the load via longtransmission lines. Therefore, the power system imposes higher requirements on the operational stability of the hydroelectric generator: the engine parameters must be carefully selected. ; The required moment of inertia is large. The appearance of a hydrogenerator is therefore different from that of a steam turbine generator. Its rotor has a large diameter and a short length. The hydrogenerator unit requires a short time to start and connect to the grid, and the operation schedule is flexible. In addition to general electricity generation, it is particularly suitable as a peak shaving unit and as an emergency backup unit. The maximum capacity of the hydrogenerator unit reached 700,000 kilowatts.

As for the principle of a generator, it is very clear in high school physics. Its operating principles are based on the law of electromagnetic induction and the law of forceelectromagnetic. Therefore, the general principle of its construction is: using suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction among themselves to generate electromagnetic energy and achieve the conversion goal of energy.

What is the principle of a hydroelectric generator (water turbine)?

The main shaft is equipped with rotor slip ring, stator slip ring, stator, rotor, stator track, impeller bypass, rotor track and pulley, etc. The stator and rotor of the brushes fixed in the interior cavity of the housing transfer the electrical energy produced. When the main shaft rotates, it drives the rotor track clockwise and drives the rotation of the direction change wheel. The stator track connected to the stator and the slip ringof the stator is driven by friction to rotate counterclockwise, so that the stator and the rotor. in the generator operates in opposite directions to achieve The purpose of increasing the speed is to improve the efficiency of electricity generation. It features simple structure, low manufacturing cost and convenient operation and maintenance.

The principle of a hydroelectric generator (water turbine) is that when water circulates through the turbine, the energy of the water is converted into mechanical energy. The rotating shaft of the turbine drives the generator rotor, which converts mechanical energy into electrical energy and produces it.

The world's first hydroelectric power station was built in France in 1878. America's first hydroelectric power station was built in Wisconsin, United States, in 1882, using a direct current generator. After 1889, alternatorsthree-phase began to be used. Since then, the capacity of a single machine has increased rapidly. In 1890, it was only 15,000 kW. By 1955, it could produce 105,000 kW generators. Before 1949, the capacity of a single unit of Chinese-made hydraulic generators did not exceed 200 kW. After 1949, the automobile industry developed vigorously. In 1958, it was able to produce a single 72,500 kW unit. In 1972, a double unit of 300,000 kW. -An internal water cooling water generator has been produced. The world's leading large-capacity hydroelectric generators are the 718,000 kVA stator water-cooled semi-umbrella hydroelectric generator of the Grand Coulee Hydroelectric Power Station, the 737 kVA stator water-cooled semi-umbrella hydroelectric generator 000 kVA Itaipu Hydroelectric Power Station and the 700,000 kVA water stator hydroelectric generator. -semi-umbrella hydroelectric generatore cooled Guli Hydropower Station, kVA air-cooled umbrella hydrogenerator and 800,000 kW Xiangjiaba hydrogenerator.Motors, etc
