Complementarity of wind energy and solar energy resources

Solar energy is the source of all the energy on the earth, and the sun shines on every part of the earth. Wind energy is another form of solar energy on the surface of the earth. Due to different forms of the earth’s surface (such as sand, ground, vegetation, ground and water), the absorption coefficient of solar radiation is different, resulting in the formation of temperature difference on the ground surface, and then the formation of air convection wind energy. Therefore, wind energy and solar energy have strong complementarities both in time and in seasons: During the day, the sun shines well, the wind is small, at night there is no light, the wind is stronger; In summer, the intensity of the sunlight is large and the wind is small, and the sunlight intensity is weak and windy in winter.
The wind energy and solar energy resources in Inner Mongolia also have such complementary characteristics. The wind energy and solar energy resources in a certain place in Inner Mongolia are used to illustrate the complementarity between the two. The site is located at 42 degrees north latitude and 111 degrees east longitude, where the solar radiation is stronger during most of the year, when the wind is weak, and when the wind is strong, the solar radiation is weaker. It can be seen that the wind and solar energy resources in this site have good complementarity.
The wind and solar complementary power supply system is widely used in the rural areas of Inner Mongolia without electricity, farmers and herdsmen scattered households and centralized households, border companies and posts, border police stations and communication base stations, such as electric field, to provide users with living power and telecom facilities and other electricity.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

126th Canton Fair

图片
On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In ...

How to maximize the efficiency of your UPS

图片
1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...
