50 megawatts of wind power requires 17 wind turbines. According to relevant information requests, 50 MW of wind power is not small. 50 MW requires an area of 350 acres and the construction of 17 wind turbines, each of which is 3 MW. The cost is around 15 to 20 million. the total investment cost is about 400 million yuan.
The first is the principle. If you can connect to the grid, then the phase, frequency and waveform of the electricity sent will be consistent with the grid. Then the load of the power grid is determined by the user, and the load is changed according to the distribution curve derived from statistics, and then the task of adjusting the load is simply left to the power plant (if convenient) . Thermal, nuclear and hydroelectric plants can all adjust load levels. Of course, nuclear power plants generally don't worklike peak power plants. Thermal power plants adjust the amount of coal burned, hydroelectric power plants adjust the water flow, and nuclear power plants are too difficult to adjust. Then came the wind power adjustment. You cannot decide the speed or direction of the wind. If it is windy, you will have electricity. If there is no wind, it will be lowered. generated. When the wind is weak, the electricity will be weak. This electricity. How can I offer it? The power grid is actually allowed to fluctuate, and it is impossible for all power plants to operate stably, so low impact is still acceptable for the large power grid. It therefore does not matter whether small-capacity wind energy is connected to the electricity grid. If you change it here, I will have to work hard to change the thermal power generation there (people at this plant will scold you).to death, it's really annoying). However, there are problems with large capacity wind energy access systems. Instability means the power supply is unreliable, which will impact the power grid. Instability is the most taboo of the power grid, so unreliable power supply is a significant problem. factor limiting the development of wind energy. So how wonderful is a big battery? If you put a large battery in a wind farm to recharge it, it can be connected to the grid when full and then recharged when empty, which can solve the problem. energy storage is good wind energy.
