The ratio of the total power generation of a wind farm in a certain period divided by the product of the number of hours in that period and the installed capacity of the power plant. (Expressed as a percentage)
Taking a certain month as an example, a generator set with a gross capacity of 300MW generates 120 million kilowatt hours, has an operating time of 436 hours, and the monthly statistical time is 720 hours, then The equivalent operating hours under gross capacity are:
(12000÷436)/30×436=400 (hours)
The gross capacity coefficient is:
400/720*100=55.56
The ratio of the annual effective utilization hours of the wind farm to the number of hours throughout the year, or the ratio of the wind farm's actual annual grid-connected electricity to the rated annual grid-connected electricity. (Expressed as a percentage)
