1. Convert the generator's electricity output to full load operating hours, which are the average operating hours (daily average, monthly average, annual average, etc.). Annual electricity generation usage hours = unit annual energy production/unit capacity
2. Analysis example:
Power generation equipment usage hours refers to the utilization level of the power generation equipment. production capacity and an indicator of its level.
The precise method is: the number of operating hours calculated by dividing the electricity production by the capacity of the electricity generation equipment during the reference period. There is another indicator with the same concept: equipment utilization, which is the ratio between the number of hours of use of electricity production equipment to the cbear of the reference period and the number of calendar hours during this period. It should be noted here that the reporting period is used. When using these two indicators, one must pay attention to the timing of the reporting period.
For example: If a 3 MW wind turbine is commissioned on January 1 and has a cumulative electricity production of 6,000 kWh at the end of the year, and another 3 MW wind turbine 2 MW goes live on July 1 and has a cumulative electricity production of 3,000 kWh by the end of the year, so they will. The usage hours are 2,000 hours and 1,500 hours, respectively, and the utilization rates are 2,000/8,760 and 1,500/4,416, respectively, or 22.8% and 34.0%. It is obvious that the utilization degree of the second wind turbine is higher. (8760 and 4416 are respectively the number of hours of the whole year and the second half of the year, 8760=24×365, 4416=24×184)
SIf converted to a year, the number of hours the hours of use are 2,000 and 3,000 hours respectively. It can also be seen that the second fan is used to a greater degree. Considering two wind turbines as a single wind farm, the whole wind farm can produce 12,000 kWh of electricity throughout the year and the installed capacity is 5 MW. The annual operating 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 electricity production is only 9,000 hours. If you divide it directly, you will get an incorrect result of 1800 hours. For renewable energy power plants such as wind farms and photovoltaic plants, many wind turbines or photovoltaic panels are often connected to the grid in batches to generate electricity. When calculating the number of hours of use, makes pay attention to the reporting period for each batch.
