The answer above is good, I'll just add it. The poster must not understand what kwh is kilowatt, h is hour, kwh is kilowatt hour. To put it bluntly, this is the degree we usually talk about. , how many degrees. To put it simply, a one watt light bulb uses one kilowatt hour of electricity for 1000 hours, a 10 watt light bulb uses one kilowatt hour of electricity for 100 hours and a 1000 watt light bulb uses one kilowatt hour of electricity per hour. 3 kW equals 3,000 watts, which means it can generate 3 degrees of electricity per hour. The poster asked the wrong question: how many kilowatt hours of electricity are produced per year. If the poster said how many watts of electricity can be produced per year, it would still be 3,000 watts. As for the number of kilowatt hours of electricity, it is 3*24*365=26,280 kilowatt hours of electricity. Let's compare and seeLet's see how much more electricity is used than the house in the original poster. Some generators are 380 V and others are 220 V. Some are 24 V car engines and are used to charge cars. It doesn't matter how many v's there are. As long as it's 3000 watts. Electricity production is 3000 watts. The original poster must also want to ask about the ratio of 220 to 3000 watts. Please ask the original question again.

That is, the rated power is 3 MW and it can generate 3,000 kWh of electricity per hour. Generally, to achieve the rated power, a rated wind speed (approximately 15 meters/second) is required.
The fan works between the input wind speed and the cut-off wind speed, which is about 3.5m/s ~ 25m/s: it cannot rotate when the wind is weak and it cannot work. if the wind is too strong and dangerous (itit therefore be stopped when a typhoon arrives).
