1 ton = 1,000 kg, the potential energy of each ton of water per meter is: 1,000 kg*9.8 m/S2=9,800 N (Newton)
Calculated in based on a water level 100 m high, the work that can be done with each ton of water is: W=9800N*100m=980000J (Joule)
And one kilowatt hour ( 1kW.h) is equal to 3600000J (3.6MJ), so the hydroelectricity production capacity per ton is:
980000/ 3600000=0.27 kWh
If the water level is less than 100 meters, the value will be reduced proportionally. If the conversion efficiency of the generator is considered to be around 50%, its value will be lower.
Model TQ-3-2 In 1969, Shanghai Electric Machinery Factory designed and manufactured for the first time dual internal cooling of 125,000 kilowatts. steam turbine generator unit The machine adopts the latest international double water internal cooling method at the time, applies reheating technologieshigh temperature and high pressure intermediate and other technologies, and is driven by direct coupling of the steam turbine. overload capacity and fully complies with the requirements of international IEC standards. It has the characteristics of high short circuit ratio, good stability for power grid, small size, light weight, low material consumption, simple system and convenient operation and maintenance. Currently, this product has been developed into a train of 50,000 to 300,000 kilowatts, with an apparent power of 62,500 to 353,000 kilowatts, an active power of 50,000 to 300,000 kilowatts, a voltage of 10,500 to 18,000 volts. , a current of 3,440 to 11,320 amps. and rotation speed of 3000 rpm, power factor is 0.8-0.85, frequency is 50 Hz, efficiency is 98.1-98.45%, stator weight is 52 to 157 tons and the weight of the rotor isfrom 18 to 57 tonnes. . It can be used for industrial and agricultural production as well as for lighting in large and medium-sized cities.
