According to current market price, they all cost between 3600-4500 yuan/kw
1.5MW may be cheaper, but it seems that the only direct drive one is Goldwind, and the price is relatively low.
2.0 MW model is the only one of Xiangdian Electric Power Co., Ltd., which is about 4,000.
The 2.5 MW model is the current main model of Goldwind, and it seems that the current quotation is relatively high
The 3.0 MW model is relatively expensive and not stable
Suppose the fan blades are installed one times every 60 seconds. A 1,500 kilowatt wind turbine generates 25 kilowatt hours of electricity per revolution.
The calculation method is as follows:
The power generated by a 1,500 kW generator in one hour is 1,500 KWH, or 1,500 kilowatt hours of electricity
p>
1,500 kilowatt hours of electricity/hour ÷ 60 revolutions/hour = 25 kWh/circle.
Detailed information:
The degree is also called kilowatt hour, which corresponds to 1 kilowatt. generator When it produces electricity for 1 hour, it generates 1 kilowatt hour of electricity.
The kilowatt (Kilowatt), one of the first units of electrical power, now tends to be extended to the unit of power throughout the field of physics. In electricity, kilowatt hour is exactly the same thing as degree, but they have different names.
1 kilowatt = 1,000 watts (Watt) = 1,000 joules (Joule)/second (Second).
1 kilowatt = 1,000 Newton meters per second (N m/s)
1 kilowatt = 0.239 kcal/s
1 kilowatt = 1.36 horsepower -steam
A kilowatt hour or kilowatt hour (symbol: kW·h; often abbreviated to degrees) is a unit of energy measurement which represents the energy consumption of a device with a power of one kilowatt after one hour of use. energy consumed.
The unit “kilowatt hour” is prMainly used to measure electricity, because the "kilowatt hour" is easier for the public to understand than the joule, and it is easier to convert to hours of use of electrical appliances. On the other hand, the joule unit of measurement is too small compared to "kilowatt hour", making it difficult to calculate. In mainland China, some public institutions also use "megawatt hour" instead of "kilowatt hour" on their billing sheets. In Chinese, “kilowatt” is sometimes written as 瓩.
1kW·h = 3,600,000 Joules = 3.6 million Joules.
The physical meaning of 1 kilowatt hour is: the electrical energy consumed by an electrical appliance with a power of 1 kW for 1 hour of work (or the work done for 1 hour of work).
One kilowatt per hour is equal to:
3.599712 × 10 joules;
1.3596112 metric horsepower per hour;
1.3408927 imperial horsepower per hour hour;
8.599712023×10 kcal.
