In fact, there are usually two reasons why wind turbines in wind farms do not rotate. Firstly, the first and most important reason is the limited load of wind farms, which means there is no consumption space on the power grid. To be frank, the electricity you sent is not consumed by users, so you must stop. Due to the fact that the entire power supply is a real-time dynamic system that cannot be stored, power generation can only be used in a timely manner to achieve dynamic balance. All resource waste is inevitable, but it also leads to serious damage to power generation companies! The country is also making efforts to change this situation by constructing ultra-high voltage and ultra high voltage transmission circuits, and sending new energy from the northwest region to places with strong electricity demand such as Shandong and Zhejiang as much as possible, in order to solve the problem of power restrictions.
Meanwhile, wind power is also an extremely unstable power source, with too much randomness to provide accurate output. With the increasing proportion of new energy, the installed capacity of stable thermal power continues to decrease, leading to power restrictions. In order to solve this problem, wind power is currently predicting the power generation capacity of wind power more accurately through wind power forecasting, and systematically allowing large enterprise electricity users to start up and operate at the appropriate time, which greatly alleviates the power restrictions of wind farms.
The second reason is that the fan has malfunctioned and maintenance must be stopped in order to resume operation. In this case, there are usually relatively few opportunities to stop. It won't stop on a large scale, and what the subject sees is more likely to be the first scenario!
