Where does the Weihui Windmill produce electricity?

On May 20, the 48 MW Weihuidong Shuanma wind farm in Xinxiang, Henan, built by Hebei Engineering Company, was connected to the grid.

Henan Xinxiang Weihui East Shuanma Wind Farm Project is located in Weihui City, Xinxiang, Henan Province, bordering the northern part of the Yellow River to the south and Taihang to the west. The total installed capacity of the project is 48 MW, with a new 110 kV booster station and a supporting 110 kV transmission line. Hebei Engineering Company undertakes construction projects such as civil road construction in wind farms, construction and installation projects of wind generators and box transformers, as well as construction and installation of 35-meter collector lines. kV.

Since the start of the project on May 1, 2017, the project department has scientifically organized and carefully deployed, taking the specifications and specifications as a starting point.he technical construction measures, and implemented safety and quality at every stage. By reasonably deploying personnel and machinery and making every effort to complete all tasks, we have overcome the impact of protecting the ancient ruins of the Great Wall, successfully completed the construction tasks, and successfully completed the plan owner node.

The pouring of the wind turbine foundations was completed on October 31, 2018, the construction of the collector line was completed on December 31, 2018, the lifting of the wind turbine was completed on January 26, 2019 and acceptance of production was adopted. on May 14, 2019. On May 19, 2019, the two collector lines and all box-type transformers were successfully connected to the grid for power generation, and the first unit was connected to the grid for power generation . The employees continued their efforts. and achieved the goal of tall grid connection and electricity production units on May 20.

How tall is the wind tower in Dongshan Donggu Village?

The wind turbine looks like a large windmill, it is silver gray. Each of these large windmills is about forty or fifty meters high, and it would take five or six people to hold them together. At the top of the wind turbine is a three-blade rotating turbine. The wheel doesn't spin very fast, and even if it does, the three blades are clearly visible. The center of the turbine is the generator and the wind turbine is shrouded inside so we can't see it. When we looked, there were almost no large windmills that weren't spinning. Even though the wind was very light, they were still turning. When the windmill spins, the whole windmill makes a sound. Listening next to the big windmill, my ears were almost numb.

How powerful is a large wind turbine?

The wind tower in Dongshan Donggu Village, Dongshan, has a column height of 46 meters and three blades 19 meters long. Dongshan Donggu Village Wind Tower has a total of 10 large windmills that rise into the sky and stand proudly in the wind. Each windmill is a generator. These large windmills are scattered along the mountains, standing tall and graceful in an orderly fashion. Against the background of blue sky and white clouds, the white wind blades rotate slowly with the wind, forming a beautiful picture.

The largest is 5 MW, one in Denmark and one in China. Generally, 2 MW, 1.5 MW or less 0.8 MW are used in China.

Formula for calculating electrical power: P=W/t =UI.

In a purely resistive circuit, according to Ohm's law U=IR and substituted by P=UI, we can also obtain: P=I2R=(U2)/R.

In dynamics: Formula of cpower calculation: P=W/t (average power);P = Fvcosα (instantaneous power).

Detailed information

When the wind turbine produces electricity, it must ensure that the output frequency is constant. This is very necessary for both grid-connected wind power generation and wind-solar hybrid power generation. ?

To ensure that the frequency of wind power is constant, one solution is to ensure a constant speed of the generator, that is, a constant speed and constant frequency operating mode , because the generator is driven by the generator. wind turbine through the transmission device, this method undoubtedly requires a constant speed of the wind turbine, which will affect the wind energy conversion efficiency.

Another way is to change the generator speed according to the wind speed and ensure that the frequency ofthe output electrical energy is constant by other means, i.e. constant frequency and variable speed operation. The wind energy utilization coefficient of the wind turbine is related to the blade tip speed ratio (the ratio of the linear speed of the turbine tip to the wind speed). There is a certain blade tip speed ratio that causes Cp to reach the maximum value.
