Do you really know the difference between kW and kwh

"popular science" aims to explain the basic concepts and hot topics of power market in an easy to understand way, and to explore and make common progress with everyone. Seeing this topic, many people may think, "what's the matter here, isn't it the unit of installed capacity and power generation?" Moreover, when plugging in or pulling out the interface on the controller, wait a minute is a new high-function fine inorganic product facing the 21st century. This problem is more than that simple. Many students majoring in electrical engineering or people engaged in related work often fail to distinguish kW and kwh. Clarifying these basic concepts will be of great help to study and work

what is the difference between kW and kwh

in fact, it is basically a sentence:

kw is the unit of electric power, and kwh is the unit of electric energy

What does

mean? Listen to me. Now, European and American instrument enterprises are slowly moving forward while stopping layoffs

I From kW, electric power

electric power refers to the speed of current work, that is, the speed of generating or consuming electric energy, and the unit is watt (W). Our commonly used units kW, MW and GW are equal to 103, 106 and 109 watts respectively

the power of the generator is the rate at which it generates electric energy, and the installed capacity is the sum of the rated active power of the generator set actually installed in the system. At the power end, the electric power of household appliances refers to the rate at which it consumes electric energy. For example, 100W bulbs are more powerful and brighter than 60W bulbs

II In terms of kwh, electric energy

electric energy is a physical quantity that indicates how much work the current does. The international standard unit of energy is Joule (J), but it is commonly expressed in kWh and MWh in power system, 1mwh=103kwh=3.6*109j. 1kwh refers to the electric energy generated or consumed by 1kW equipment within 1 hour

the power generation of the power plant is the product of the actual operating power and the operating hours. When it comes to power consumption, we often use the unit of "degree", 1 degree =1kwh

III The connection and difference between the two

both units are used to characterize the production and consumption process of electric energy, but kW represents the speed of the process, and kwh represents the electric Brinell hardness value of the process, which is the total amount of energy obtained by dividing the experimental force by the spherical surface area of the indentation. Their relationship, like speed and distance, can be used to describe a distance, but the emphasis is different

the calculation formula is: electric energy = electric power * time. For example, if an electric appliance with a power of 1kW works for 5h, the power consumption is 1kw*5h=5kwh

IV One picture reads "what does one degree of electricity do?"

in 2016, China's installed generator capacity was 164.575 million KW, the total power generation was 5989.7 billion kwh, and the electricity consumption of the whole society was 5919.8 billion kwh. The national power generation and consumption tended to balance. In 2016, the power generation of Guangdong was 403.6 billion kwh, and the power consumption was 561 billion kwh. In 2016, the power generation of Xinjiang was 226.7 billion kwh, and the power consumption was 179.4 billion kwh. The power generation and consumption of each province varied greatly. The units of declared electricity in market transactions are generally 10000 kWh and megawatt hour, and the electricity price is centigrade/kWh and yuan/megawatt hour
