Construction starts on China's longest power highway

Construction starts on China's longest power highway

How far is it from Jiuquan, Gansu to Xiangtan, Hunan? China's most cattle transmission line measured with its own footsteps: 2383 kilometers! This is currently China's UHV transmission from the farthest line... June 3, 2015, Jiuquan-Hunan ± 800 kV HVDC transmission project started, marking the UHV power grid into a comprehensive speed, large-scale construction of the new stage. Jiuquan-Hunan UHV Tips Passing through 5 Provinces (Cities) of Gansu, Shaanxi, Chongqing, Hubei and Hunan Newly Built Jiuquan and Xiangtan Converter Stations with a Converter Capacity of 16 million kW and a Total Length of 2383km Project Investment of 26.2 billion Yuan Planned in 2017

Scientists use lignocellulose nanofibers to make soft batteries

Scientists use lignocellulose nanofibers to make soft batteries

Cellulose nanofibrils (cellulosenanofibril,CNF) generated from wood pulp is known as the latest wonder material, which is a natural, renewable and cheap carbon nanotube. A team of scientists from the Royal Institute of Technology (KTH) in Sweden and Stanford University in the United States used this material to make a soft battery, which is more resistant to impact and impact than traditional hard batteries, and can resist high-strength pressure. The science team used CNF to create a lightweight porous aerogel-like substance, which KTH scientists MaxHamedi as "similar to a foam mattress,

Lin Boqiang: How to Optimize Power Distribution to Adapt to Economic

Lin Boqiang: How to Optimize Power Distribution to Adapt to Economic "New Normal"

Due to the new normal of economic development, the development of China's power industry will face three new characteristics, which are both challenges and opportunities for power development: first, the growth rate of power demand will slow down; second, the economic transformation will change the power load curve, making the load The peak-valley difference becomes larger; the third is the increase in the share of new energy. If the traditional new power plant is used to deal with the rapid growth of the highest load, it will inevitably lead to a decrease in average utilization hours and a decrease in unit load rate, which will have a negative impact on the efficiency of the entire power system. On the other hand, simply reducing the installed capacity of thermal power to improve the utilization hours may not be conducive to the safety of the power system. modern power grid safety

How to achieve low loss design of high power density module power supply?

How to achieve low loss design of high power density module power supply?

High power density module power supply currently occupies a dominant position in China's industry, communications and manufacturing fields. How to achieve low loss and heat dissipation balance of high frequency power supply in the design process has become the number one problem faced by many manufacturers and R & D personnel. This article will be a brief narrative analysis of this issue to help engineers more effectively achieve low-loss high-power power design. First of all, we take the application in the field of communication as the starting point, and look at the reasons why high-power and high-density power supplies have rapidly occupied the market in recent years. In the field of communication equipment design and development in China, it has always been based on low power.
