Wind farms are very different from conventional power plants, and what are the fundamental reasons f

1) The unit capacity of wind turbines is small;

2) The energy production method of wind farms is relatively dispersed, with a large number of production units;

3) The output voltage of wind turbines is low;

4) The types of wind turbines are diverse

5) The power output characteristics of wind farms are complex; >

6) Wind turbines are connected to the grid. Electronic power conversion equipment is required.

1 Wind power construction in China is encouraged by the state and implemented by many state-owned enterprises. This is a kind of performance that has little to do with efficiency. There is private wind energy, and these are all good places, places where energy can be sent, otherwise the private sector will not invest;

2 The instability of Wind energy is a fait accompli, and it’s the same everywhere. It is understandable that theThe electricity grid company does not want to accept it. The grid's acceptance of wind power cannot reduce the capacity of thermal power plants, because once the wind disappears, thermal units must be started immediately to meet the grid's load needs. The start-up process for thermal units is very long. , and the coal consumption during this period is very large, which is very unprofitable and dangerous;

3 Now the power grid company requires new wind power plants to be equipped with storage facilities of energy. Battery banks are used to store energy. However, the battery capacity is not large and it is impossible to store a large amount of electricity. It can only solve a temporary problem and cannot solve the power supply capacity without wind for a long time;

4 The biggest problem relatedstorage of wind capacity is as follows: the wind farms are all in the Western Desert. Many state-owned companies have built wind farms there, but there are no nearby lines to carry electricity. It is completely inappropriate to build lines specifically for wind power, because no matter how big wind power is, its capacity is very low from a grid perspective and compared to thermal power plants. The line dedicated to a circuit has an extremely low utilization rate and, combined with investment in maintenance, it is very inappropriate.
