80 meters. The air pressure of a 300 kW hydroelectric generator is 0.8 MPa, which is equivalent to a water depth of 80 meters. 6.5 cubic meters of water can generate one kilowatt hour of electricity. can generate 6.15 kilowatt hours of electricity. The tap is 80 meters away. A generator is a mechanical device that converts other forms of energy into electrical energy.
A 200kw hydroelectric generator requires water pressure
a waterfall of 2.2M, with a maximum water height of 2.2M. Take 2M for the calculation, and the flow rate is 1L/S. Gravitational potential energy T=mgh, P=mgh/t=1000*10*2=20000J/s=20000/3.6=5.5KW
The efficiency of the original owner's homemade turbine will not exceed not 50% because that’s too small .
The motor efficiency will not exceed 85%
The power is therefore conservatively estimated at around 2 kW.
The water height being too low, the poster needs a blade turbineaxial flow heads, and he can make one himself. Next, engage the gearbox at high speed. This can achieve higher efficiency.
Since the power is too low, a 3 kW DC motor can be used with a relatively simple structure, and then an inverter can be added.
How much water does an 8000 kW hydroelectric generator use?
A 200 kW hydroelectric generator requires 10 to 15 mV of water pressure.
A hydroelectric generator is a machine that converts the kinetic energy of water flow into electrical energy. When designing and operating a hydroelectric generator, two major parameters, water height (difference in water level) and flow rate, are mainly considered. considered. Water height refers to the height to which the water falls, which determines the kinetic energy conversion capacity of the water to the turbine; the dflow rate refers to the amount of water passing through the turbine per unit time, which determines the power generated by the turbine; the generator. Therefore, for a 200 kW hydroelectric generator, the design head and flow rate should be determined, and the water pressure can be calculated based on the selected head and flow rate.
How to make a small, high-efficiency 1000w homemade hydroelectric generator The water height is not very high and the flow rate is very slow
The 8000-. A kilowatt hydroelectric generator uses 355 million cubic meters of water.
Water used for hydroelectric power generation of units 4 × 2,000 kW = 8,000 kW, the average water consumption for many years is 355 million meters cubic, so the 8,000 kW hydroelectric generator uses 355 million cubic meters of water. water.
A motor madereferring to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction.
It is difficult and unprofitable to make a small hydroelectric generator yourself.
To obtain high efficiency from a small 1000W hydroelectric generator, an impact hydroelectric generator set can be selected.
The impulse hydraulic generator set is also called horizontal hydraulic generator set. Like the oblique impact hydraulic generator, it is a hydraulic generator with high water head and low flow. The required water height range is: 7-40. meters. It is suitable for use in high mountain areas. Its working principle is as follows: in the hydraulic turbine, the jet coming out of the nozzle is not in the tangential direction, but in the direction forming a certain anglewith the runner's rotation plane. The runner enters the bucket on one side and exits the bucket on the other side. The main features of the impact hydroelectric generator set are:
1. Under normal water conditions, water resources can be reasonably used to generate electricity.
2. If there is a rainy and dry period and there is no water, the diesel engine can be used to generate electricity.
For a small hydroelectric generator of about 1 kW, the market price is about 1,000 yuan. It is much cheaper and faster to buy it directly than to make your own.
For small hydroelectric generators of around 1 kW, the most important thing to consider is its operational stability and reliability. It is recommended not to think too much about efficiency. After all, for a unit with a power of 1 kW, the difference between the power of 70% and 60%is 100 W. There is no need to invest more for 100 W.
