What about Hegang Electric Power Construction and Installation Engineering Co., Ltd.?

Introduction: Hegang Electric Power Construction and Installation Engineering Co., Ltd. Wind power generation, the construction foundation of wind energy resources in China 1. Overview of China's abundant wind energy resources, the exploitable wind energy reserves are about 654.38+0 billion kW, of which the onshore wind energy reserves are about 253 million kW (calculated by the data of the height of 654.38+00 m above the ground), and the offshore wind energy reserves are about 750 million kW, accounting for 6,552,003, and the national installed capacity is about. 2. Distribution of wind energy resources 1. The wind energy-rich areas in the "Three North" (Northeast China, North China and Northwest China) include nearly 200km wide areas in the three northeastern provinces, Hebei, Inner Mongolia, Gansu, Qinghai, Tibet and Xinjiang. The wind power density is above 200 ~ 300 w/m2, and some of them can reach above 500W/m2, which can be developed. Wind farms in this area have flat terrain, convenient transportation and no destructive wind speed, which is the largest wind energy resource area in China and is conducive to the large-scale development of wind farms. However, attention should be paid to the influence of low temperature and sandstorm when building wind farms. In some places, the interconnection conditions are poor, so it is necessary to coordinate development with the power grid. 2. The southeast coast of the wind energy-rich belt is affected by the Taiwan Province Strait. Whenever cold air reaches the strait southward, the wind speed increases due to the narrow tube effect. Cold air in winter and spring and typhoons in summer and autumn can affect coastal areas and their islands, which is the best area for wind energy enrichment in China. China's coastline is about 1800km long and there are more than 6,000 islands, which is a region with great prospects for wind energy development and utilization. In coastal and island wind energy-rich areas, the annual effective wind power density is above 200W/m2, and the wind power density line is parallel to the coastline. The wind power density of coastal islands is above 500W/m2, such as Taishan, Pingtan, Dongshan, Lu Nan, Chen Da, Shengsi, Nan 'ao, Mazu, Magong and Dongsha, and the available hours are about 7,000 to 8,000 hours. This area, especially the southeast coast, is hilly from the coast to the inland, and the area rich in wind energy is only within 50 kilometers from the coast. 3. The inland local wind energy enrichment area is outside the two wind energy enrichment areas, the wind power density is generally below 100W/m2, and the available hours are below 3,000 hours. However, due to the influence of lakes and special topography, some areas are also rich in wind energy, such as near Poyang Lake, Hengshan Mountain in Hunan, Jiugong Mountain in Hubei, Songshan Mountain in Henan, Wutai Mountain in Shanxi, Huangshan Mountain in Anhui and Taihua Mountain in Yunnan. 4. China is rich in offshore wind energy resources, and the highly available wind energy resources of 10m m are about 700 million kW. The offshore wind speed is high and the quiet period is short, which can effectively utilize the power generation capacity of wind turbines. The sea surface roughness is low, and the wind speed changes little with height, which can reduce the tower height. The turbulence intensity of offshore wind is low, and there is no influence of complex terrain on airflow, which can reduce the fatigue load of the fan and prolong the service life. It is generally estimated that the wind speed at sea is 20% higher than that along the plain coast, and the power generation increases by 70%. A fan with a design life of 20 years on land can reach 25 to 30 years at sea, and it is close to the power load center. With the development of offshore wind farm technology, offshore wind farm is economically feasible and will inevitably become an important sustainable energy source in the future.
