Electricity production hours: time during the statistical period during which wind energy production is converted to full load, i.e. total electricity production divided by nominal installed capacity of the wind turbine.
Effective Wind Hours: The cumulative running time of the fan between the start wind speed and the start wind speed during the statistical period.
Startup wind speed refers to the wind speed that meets the grid connection conditions, that is, the lowest wind speed that can produce electricity. If the wind speed is lower than this, it will occur automatically. close. The starting speed is related to the aerodynamic performance of the fan blades. When the cut-in wind speed is reached, the generator can produce electricity continuously and stably.
The speed of vCutoff speed refers to the maximum wind speed at which the wind turbine is connected to the grid to produce electricity. If the wind speed exceeds this speed, the unit will be cut off from the network. which means the wind turbine will shut down and stop producing electricity. The cutoff wind speed is not only related to the blades, but also to the unit load. If the cut-off wind speed is reached but not cut off, there may be risks of tower collapse, turbine overspeed, etc. accidents.
