The power generated by converting the mechanical energy of the main motor into electrical energy. The active power of a hydroelectric generator refers to the power generated by converting the mechanical energy of the main engine into electrical energy. Active power is the actual energy consumed by the equipment. The reactive power emitted by the generator is the power generated by the generator to establish a magnetic field. Reactive power is not useless power. It can establish a magnetic field, increase voltage, and be used for energy conversion and transmission.
How to make a small, high-efficiency 1000 W homemade hydroelectric generator. The water height is not very high and the flow rate is very slow,
1.6 meters cubes. According to the query "Hydropower Technology and Engineering", it is known that the height difference of 150 meters of a hydroelectric power production unitpower of 500 kilowatts is 0.4 to 0.5 cubic meters per second. According to the generator conversion efficiency of 0.7, the. the required water flow is 1.6 cubic meters per hour. The kilowatt was originally a unit of electrical power and is becoming a unit of power throughout the field of physics.
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 principleoperation 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 angle with the plane of rotation of the It enters the bucket through one side of the slide , then exits through the leaf of 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 itsoperational 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.
