What are the main factors affecting power generation?

The main factors that affect power generation are:

The impact of turbulence, wake impact, aerodynamic loss due to blade pollution, power curve, wind turbine availability, wind farm internal line loss, and lag to the wind device Impact, climate impact.

Power generation includes thermal power generation, hydropower generation, nuclear power generation and other power generation (such as geothermal power generation, solar power generation, wind power generation, tidal power generation and biological can generate electricity). Power generation includes self-consumption of power plants (including self-contained power plants) (commonly known as plant power), power generation before new power generation equipment is put into operation, and power generation during trial operation after power generation equipment is overhauled or renovated; any power generated by the factory or the user The utilization should be counted in the power generation, and the unused power should not be counted in the water. The power generation does not include the power generation of electric AC-DC conversion units, exciters, and cycle conversion equipment. The amount of electricity generated is calculated based on the difference between the current period and the previous period's indication on the generating unit's watt-hour meter. The watt-hour meter indication is based on 24:00 on the last day of the period.

For example, there are 33 1500KW wind turbines. How to calculate the annual power generation of the wind farm?

The power factor of the turbine generator has a rated value and A permissible range of variation. Each specific unit has its own power curve. When the generator operates under rated parameters, it does not affect the active power, that is, it does not affect the power generation. When the system voltage changes, the reactive power curve given to complete the dispatch has an impact on the power generation.

For example, if the system voltage is low, scheduling requires as much reactive power as possible. At this time, when the stator and rotor currents of the generator do not exceed the rated value, the active power may be lower than the rated value, which means less power generation. When the system voltage is high, less reactive power needs to be carried, which will not affect the power generation. However, it is necessary to pay attention to the generator outlet voltage not being too low, otherwise it will affect the safety of the factory's electricity.

Calculation formula: [(60*10^3*2799.3+40*10^3*2791.7)-100*10^3*2180]/3600=17118KW

Can be matched 18MW steam turbine generator set.

It depends on the annual average wind speed in the area where your wind farm is located, the annual unavailable wind speed (that is, less than 3.5m/s and greater than 25m/s), the availability coefficient of the wind turbine, the power curve of the generator, etc. Considering many factors, it should generally be equivalent to about 2,000 hours of full power, which is 1,500 (kw) x 33 x 2,000 (h) = 100 million degrees.
