The power plant has an “installed capacity,” which is the total rated power of the generator, ××10,000 kilowatt hours, and the annual electricity production is ×××10,000 kilowatt hours. Unit capacity refers to the generator's rated power, MW. In fact, the generator generates active and reactive power, and the power is the capacity, which is represented by S and the unit is KVA. Therefore, the unit of production is expressed. in watts.
Electricity production refers to the amount of electrical energy produced by the generator through energy conversion. The unit of measurement for electricity production is the “kilowatt hour.”
Electricity generation includes thermal power generation, hydroelectric power generation, nuclear power generation and other forms of energy production (such as electricity production). geothermal energy, solar energy production, solar energy productionction of wind energy, tidal energy production and biological electricity production).
Electricity production includes self-consumption of power plants (including captive power plants) (commonly known as plant energy), the production of electricity before the commissioning of new production equipment of electricity and electricity production during operational tests after power-up. production equipment is overhauled or renovated; All those used by the factory or users must be taken into account in the production of electricity, and those which are not used but released into the water must not be included.
Electricity generation does not include the energy production of AC-DC electrical conversion units, exciters and cycle conversion equipment. The quantity of electricity produced is calculated based on the difference between the pcurrent period and the indication of the previous period on the watt-hour meter of the production unit. The watt-hour meter indication is based on 24:00 on the last day of the period.
The total amount of electricity produced by all electricity generation sectors (including thermal power, hydropower, nuclear power, solar power, wind power, tidal energy, etc.) during a specific period and in a specific region.
Electric energy consists of active power and reactive power
The speed of the generator adjusts the active power and the excitation current adjusts the reactive power< /p>
Generator and power grid Connected, usually working in parallel with the power grid, the generator will not deliberately increase the output power when the user uses electricity because the power grid supports it. Generally, if there areenough energy during the day, it will operate at full capacity. rated power. At night, the output power will be reduced because AC electrical energy is not stored for unnecessary energy waste, which is also a restriction of the power grid of power plants.
In one sentence, the relationship between user-grid-generator is that the generator first transmits electricity to the Internet and then reaches the user, so the power grid is the third party between the user and the generator Haha
