Wind energy resources are clean renewable energy sources. They refer to the kinetic energy formed by the solar radiation that radiates unevenly on the surface of the earth, causing uneven heating in the atmosphere, thereby moving the air in the horizontal direction and flowing the air. It is a form of conversion of solar energy. Scientific and accurate estimation of China's wind energy potential and its spatial distribution is an extremely important basic work for the development of wind energy resources.
Wind energy resources in China are a kind of clean renewable energy. It refers to the kinetic energy formed by the solar radiation radiating from the surface of the earth, causing uneven heating in the atmosphere, causing the air to move in the horizontal direction. . It is a form of conversion of solar energy, but the cost of wind energy development and utilization is lower than the cost of solar energy development and utilization. It is the most promising energy source among renewable energy.
China's wind energy resources are rich in the northwestern Inner Mongolia plateau and southeastern coastal areas.
Reasons for the abundant wind energy resources in the Inner Mongolia Plateau:(1) The terrain of Inner Mongolia Plateau is flat, the vegetation is sparse, and the terrain blocking effect is small;
(2) Close to the winter wind source, the winter wind is strong.
Reasons for abundant wind energy resources in the southeast coastal areas:
It is close to the Pacific Ocean and has a small barrier to the terrain, and the summer wind is strong.
1. Land and sea location (wind energy resources in coastal areas are more abundant than in the mainland)
2. Underlying surface (roughness, vegetation intensity, topography.)
3. Atmospheric circulation, monsoon effects (some areas are closer to the wind source or strongly affected by a monsoon)
4. The canyon terrain causes a narrow tube effect (the wind blows in the valley mouth and is squeezed to make the isobar line dense winds become larger)
5. The other is the wind belt (such as the Antarctic has a strong polar east wind)
Reasons for the rich wind energy resources in western Europe1 temperate ocean climate west wind belt, the west wind is popular all year round, the wind is strong;
2 The air resistance around the ocean is small, and the coastal wind is large;
3 The west side is located on the windward side of the prevailing west wind, and the wind resources are abundant;
4 The overall terrain of western Europe is relatively low, and the barrier to the west wind is limited, so the wind energy in the east side is also abundant.
China's wind energy resources rich areas
1. The southeast coast and its islands are the largest wind energy resource areas in China.
2. Inner Mongolia and northern Gansu are the second largest wind energy resource areas in China.
3. Heilongjiang and eastern Jilin and the coastal areas of Liaodong Peninsula have large wind energy.
4. The northern part of the Qinghai-Tibet Plateau and the Three North Region and the coastal area are large wind energy areas.
5. Yunguichuan, Gansu, southwestern Shaanxi, Henan, western Hunan, mountainous areas of Fujian, Guangdong, Guangxi, and the Tarim Basin are the smallest wind energy regions in China.
6. In the vast areas outside the 4 and 5 regions, it is the wind energy season utilization area.
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
