How much heat can the heat loss of a 1000 MW generator raise in 1 kg of water?

Introduction How much heat can the heat loss of a 1000 MW generator raise in 1 kg of water? e...Do you know what a 1000 MW generator is? Single unit of the Three Gorges hydroelectric power station

How much heat can the heat loss of a 1000 MW generator raise in 1 kg of water?

e...

Do you know what a 1000 MW generator is?

The maximum capacity of a single unit of the Three Gorges Power Station is 700 MW.

The capacity of a single unit of the Taishan nuclear power plant is 1,750 MW. >

The hydroelectric power production of the Three Gorges Taking a machine as an example, its efficiency is about 93% and its loss is 7%...

What is the concept of 70MW?

This is all the power of a small thermal power plant. In other words, you use the power of a power plant to heat two bottles of mineral water...

And to calculate the temperature increase, there must be Time.. If we don't give the heating time, there is no way to calculate it.

70,000,000 W * 1 e-6 s / (4.17843 J/g*C * 1,000 g) = 16.75 C

The calculation at the bottom is wrong , it should be 1 per microsecond e -6 s, an increase of 16.75 degrees Celsius.

Assuming the water temperature is 10 degrees, it will vaporize in 6us.6e-6s.

Water molecules will decompose at a temperature of 5700 Kelvin

According to this algorithm, it will take approximately 3.4 ms, 3.4 e-3s, and molecules water will no longer exist. By the way, the temperature has reached the surface temperature of the sun.

e... Why do I have to talk so much... For a person who can even clearly distribute the units of power and the units of heat...

The units of power are in mW, W, kW, MW Watt

The unit of energy is J, kJ Joule

When the power of the turbine acts on the motor, is it engine capacity? For example, if the turbine power is 1000 kW, then the generator capacity is 1000 KVA?

It is recommended to directly enter the 1000 kW hydraulic generator on Baidu and view the corresponding manufacturer's quotation above. It generates 1,000 kilowattheures of electricity every hour. As for the flow rate, since I have to go to work, you can calculate N=9.81QHn yourself. n is the hydraulic loss coefficient, which generally takes between 0.9 and 0.98.

A 2 meter can be calculated. a high water load powers a 1,000 kilowatt generator?

First of all, we need to clearly distinguish between power and capacity. The unit of power is kW and the unit of capacity is kVA.

There is a calculation formula for power and capacity, kW = power factor × kVA.

Second, the power of the turbine acts on the engine. To express the engine capacity, the following calculations are necessary: ​​

Generator power = generator efficiency × turbine power

> Generator capacity = generator power/power factor power

Third, the efficiency of a small generator can be as low as 0.9, when the power factoris also 0.9.

The turbine power you mentioned is 1000 kW and the generator capacity is 1000 kW.kva is established

No. The water height is 2 meters high, and the power that can be installed is 1.0976 kW. A 1000 kW generator cannot be driven and must be replaced. Water head refers to the mechanical energy of the liquid per unit weight, including position head, pressure head and flow head. The sum of the three is the total height. The sum of the position height and the pressure height is the pressure height.
