Internet of Things encountered problems: how to meet the power supply needs?
Looking into the characteristics of the Internet of things, you will find that the Internet of things to effectively promote the power needs of the problem must be overcome. System power over Ethernet is one of the options. At the same time, PoE solutions are rapidly emerging in the marketplace, growing in popularity. In addition to PoE technology, micro-power harvesting technology is also a direction that can not be ignored.
Chongqing Zhongzhou third batch of direct electricity trading companies can declare ultra-low price
Large electricity users can docking with power generation companies to reduce the power supply intermediate links, significantly reduce the cost of electricity companies and enhance their market competitiveness. Recently, Zhongzhou City Commission by letter launched the third batch of 2017 pilot direct electricity trading, business success can enjoy ultra-low price.
Municipal Commission of Science and Technology to build large electricity users docking platform and power supply companies, enterprises and power companies can negotiate tariffs and reduce business costs. As long as they are in line with the state industrial policies, environmental protection policies, energy conservation and emission reduction policies, the annual electricity consumption of 5 million kilowatt hours and above, companies can participate in direct transactions on their own; to allow power companies to proxy users to participate in direct transactions, allowing organizations to use electricity 300 Users of more than one thousand kilowatt hours "bundled" involved in direct transactions. Power users involved in direct transactions are required to complete the access procedures. Eligible enterprises may apply to the county Commission of credit, the need to provide the basic information of electricity users, business license, letter of commitment, to be involved in the third batch of 2017 electricity direct transaction power monthly plan. The deadline for this application is May 15.

Xu Ji UHV technology for the first time out of the country boost "Belt and Road"
May 2, in the State Grid Corporation of e-commerce platform for publicity, "China Power Technology Equipment Co., Ltd. in Pakistan, Matilda - Lahore ± 660 kV DC transmission project bid list," Xu Ji Group Co., Ltd. list . In this major project involving the priority projects of energy cooperation in the CAB Economic Corridor and the major projects of the "One Belt and One Road" project, Xuji Group relies on its excellent technology and first-class quality in the design of converter valves, DC protection and control systems And measuring devices and other fields come to the fore, winning the amount of yuan.
The Malatyari-Lahore ± 660 kV HVDC project in Pakistan is the first foreign investment project in Pakistan's first HVDC transmission and transmission field. The route starts at the Mehdiar converter station about 180 km north of Karachi, the largest city in Pakistan and finally reaches the Lahore converter station about 40 km southwest of Lahore, the second largest city, from southwest to northeast, Pass Sindh and Punjab provinces. The project uses ± 660 kV DC transmission technology, transmission capacity of 4 million kilowatts, the total length of 878 km line, Pakistan is currently the highest voltage level, the longest transmission distance, transmission capacity of the largest transmission line.
Construction of the National Security Xin'an District State Grid to do so
State Grid Corporation has set up by the chairman of Shuyin Biao served as the leading group for the development of Xiong'an District; Xianan District, the initial establishment of power supply company preparatory team, from the State Grid Corporation of the system-wide deployment of power, responsible for the specific planning and construction of the new district power, safety Production, supply services and other work.
State Grid Corporation of Hebei Province Electric Power Company revealed that the power supply company in Xinan District ready to Baoding power supply companies and Xiongxian, Rongcheng, security of the three county power company completely decoupled, based on zero foundation set up.
The location conditions are good, the existing development is low, is considered to be the biggest advantage of Xiong'an District. The existing population of Xiongxian, Rongcheng and Anxin 3 counties is about 1.1 million with a total electricity consumption of over 4.2 billion kwh. The starting area of ​​100 km2 is mainly located between Anxin County and Rongcheng County. Most of this area Is the basic farmland.
At present, the state grid company is taking the initiative to dock the Preparatory Commission of Xiong'an District, take the initiative to cooperate with the planning of the municipal security planning, research and development of the planning and construction of the power grid in the new security area proposed to be high starting point high standards of high quality to create "green low-carbon, Friendly and convenient, strong and reliable, "a world-class green smart grid.
HARTING: Push-pull V4 industrial connectors for process reliability through easy operation
SHANGHAI, May 9, 2017 --- The new HARTING push-pull V4 industrial connector features a new housing material that is resistant to high aggressive chemicals and features locking devices and a more flexible cable entry. These innovations - and many more - allow users to achieve higher process reliability and push-pull connectors for more demanding applications. HARTING push-pull V4 industrial connectors enable data, signal and power transmission with a modular concept.

The world's first UHV AC line across the DC line in Linyi, Shandong completed
On May 5, the world's first UHV AC line across UHV DC line construction was successfully completed in Linyi, Shandong Province, accumulating valuable actual combat experience for similar cross-span construction in the future.
Linyi converter station under construction - Linyi substation 1000 kV line project ("Linyi first-line" project), is connected ± 800 kV Shanghai Temple - Shandong Linyi converter station and 1000 kV substation Linyi substation project, the project In Linyi Yinan within the span of ± 800 kV Ximeng - Taizhou line under construction. This is the first time in the history of UHV construction that AC transmission lines spanned the construction of DC transmission lines and was delivered by Shandong Transmission and Distribution Engineering Company and successfully completed.
"Thirteenth Five-Year" planning project Central China UHV ring network site selection Hubei Xinzhou
Electricity to replace coal with electricity to reduce energy consumption and improve efficiency. Wuhan Municipal Development and Reform Commission recently revealed that the State Grid "Huazhong UHV ring network" site located in Xinzhou and Hong'an bordering areas, has made the provincial, municipal and local governments all support materials, and adopted the State Power Planning and Design Institute Hospital review, to be approved by the National Development and Reform Commission will start construction.
According to previous media reports, China plans to build a UHV power grid in North China, East China and Central China ("Sanhua") to form a "three vertical, three horizontal and one ring network." In our country, UHV refers to the voltage level of DC of ± 800 kV and above and AC of 1000 kV and above. Popular interpretation is that the use of high voltage transmission lines, power transmission more than the same period, loss less efficient and more efficient, longer transmission distance, more provincial land resources.
In addition to finalizing the site selection for UHV ring network in Huazhong, a new 1000 kV UHV AC substation and ± 800 kV UHVDC converter will also be planned in accordance with the requirements of "UHV city by city and ultra-high pressure entering the city" in Wuhan. Station, and in Jiangbei, Jiangnan build a 500 kV EHV substations, the project has been included in the State Grid "Thirteen Five" project library, and strive to be completed and put into operation during the "13th Five-Year" period.
