1. Convert the power generation of the generator to the operating hours at full load operation, which is the average operating hours (daily average, monthly average, annual average, etc.). Annual power generation utilization hours = annual power generation of the unit/unit capacity
2. Example analysis:
The utilization hours of power generation equipment refers to the utilization level of power generation equipment production capacity and an indicator of its level.
The accurate method is: the number of operating hours calculated by dividing the power generation by the capacity of the power generation equipment during the reporting period. There is another indicator with the same concept: equipment utilization, which is the ratio of the number of hours of power generation equipment utilization in the reporting period to the number of calendar hours in that period. It should be noted here that the reporting period is used. When using these two indicators, we must pay attention to when the reporting period is.
For example: If a 3MW wind turbine is put into operation on January 1st and has a cumulative power generation of 6000kWh by the end of the year, and another 2MW wind turbine is put into operation on July 1st and has a cumulative power generation of 3000kWh by the end of the year, then they will The utilization hours are 2000 hours and 1500 hours respectively, and the utilization rates are 2000/8760 and 1500/4416 respectively, that is, 22.8% and 34.0%. It is obvious that the utilization degree of the second wind turbine is higher. (8760 and 4416 are the number of hours in the whole year and the second half of the year respectively, 8760=24×365, 4416=24×184)
If converted into one year, the number of utilization hours are 2000 and 3000 hours respectively. It can also be seen that the second fan is utilized to a higher degree. Considering two wind turbines as one wind farm, the entire wind farm can generate 12,000kWh of electricity throughout the year, and the installed capacity is 5MW. The annual utilization hours of the wind farm are 2,400 hours. If you don't pay attention to the reporting period and add it up directly, the power generation is only 9,000 hours. If you directly divide it, you will get an incorrect result of 1,800 hours. For renewable energy power plants such as wind farms and photovoltaic power stations, many wind turbines or photovoltaic panels are often connected to the grid in batches to generate electricity. When calculating the number of utilization hours, attention should be paid to the reporting period of each batch.
