Matching of electric field and power grid.
1. The matching problem of wind power generation includes two aspects. One is the matching of wind resources between wind turbine generators and wind farms.
2. The second is the matching of wind farms and power grids. The larger the installed capacity of a thermal power plant, the more power it generates, but wind power generation is different. Wind turbines must match wind farm resources to increase power generation.
3. In addition, in a power grid with wind power generation, the bigger the wind farm capacity, the better. Only by maintaining a certain ratio can the power system be ensured to operate reliably, stably and economically. This is the wind farm. Matching problem with the power grid. For a specific wind farm, the power output of a wind turbine depends on a variety of factors.
At what level is wind power generally suitable for power generation?
The capacity of 33 Tai 1.5MW wind turbine should be 49.5MW. If the designed total installed capacity is 200MW, these 33 units should be only the first phase of the project. But these 33 units should be considered small wind farms. If 200MW is installed, it should be considered medium and large.
I am talking about inland wind farms. I don’t know about offshore ones.
This is a 2.0MW wind turbine. How much electricity can it generate on average every day
For wind power generation, the concept of how many levels of wind power is used is too rough. Due to different generator capacities, the requirements for wind speed are also somewhat different. However, generally if the wind speed exceeds 3m/s, the wind turbine can generate electricity. However, wind power generation does not depend on how high the local wind speed can reach, but on how long the local wind farm that generates electricity for this wind turbine can operate per year. Based on the current wind power subsidy price set by the state, if the power generation time is less than 2,000 hours that year, there will be no profit.
A 2MW wind turbine, that is, a 2000KW wind turbine, can generate 2,000 kilowatt hours of electricity in one hour at full power. Depending on the wind farm, the annual full power generation hours of the wind farm are different. Taking a wind farm with 3000h annual power generation hours as an example: 3000/365*2000=16384 kWh.
It depends on the capacity of the single machine (the electric energy generated by 850KW, 1MW, 1.5MW, 2MW, 3MW, etc. is definitely different), and it also depends on the wind operation. 1 kilowatt hour of electricity = 1KW·h. According to this calculation, an 850KW wind turbine can generate 850*24=20400KW·h every day. This is the theoretical value. It also depends on wind conditions, power transmission and transformation losses, etc.
Extended information:
Due to the unstable air volume, the wind turbine output It is alternating current of 13~25V, which must be rectified by the charger and then charge the battery, so that the electrical energy generated by the wind turbine can be converted into chemical energy. Then use an inverter power supply with a protection circuit to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.
Mechanical connection and power transmission: The horizontal axis fan blades are connected to the universal elastic coupling through the gearbox and its high-speed shaft to transmit the torque to the transmission shaft of the generator. This coupling should have good The characteristics of damping and vibration absorption are shown in absorbing the appropriate amount of radial, axial and certain angular deflections, and the coupling can prevent the overload of the mechanical device.
