Education should be oriented to scientific and practical applications. Therefore, we propose students study with methods "Learning by Doing", "Project Based Training" "Solving Problems in an Efficient Way". Through this introduce them industry style development work. This paper describes the process how teach learn activities rebuilding a standard PC Power Supply into 36V/12V DC supply which is used small electric vehicles as on board supply. Basis knowledge essential parts of general...

Energy efficiency depends on the profit that consumed energy contributes to human need system for sustainable development. With increasing importance of coordinate development environment, economic and electric power system, it is more difficult choose right improvement path mechanism in electric-power supply demand system. After analyzing feedback which caused growth ceiling was found along with some inhibition factors process improvement. In view end treatment introduced as a...

The energy metering of high-voltage transmission lines usually adopts voltage transformer PT to reduce the voltage, and then combines with current CT on secondary terminal. reason is that phase difference cannot be directly obtained. In order overcome problem traditional electric device measure lines, this paper proposes a noncontact method obtain based field coupling method, uses open-ended effective value current. practical test shows easy use, low cost, stable reliable, can meet direct...

Eelectric power resources security is very important for the sustainable development of industry. However, supply electric depends on alternative To develop exhaustible are not a long way while their quality and quantity good our demand. invest industry necessary choose country. Through intruduction into production function investment set as controllable variable. Then, path to achieve by adjusting variables were explored some suggestions put forward control industries.

In view of broad and deep economic impact economy society from business ethics enterprise can not avoid the existence ethics, as values, spirit, pursuit ideal ,behavior habits, morality so on reflecting in activity, its orientation to dominant role behavior is very obvious. this paper, analysis Marxist economics, institutional welfare economics ecological demonstrate necessity for sustainable development enterprises.

Considering the sustainability of electric power’s consumption and multi-usage exhaustibility coal resources, along with substitutability power resources (EPR) under certain condition, this paper constructed a dynamic pricing model EPR. By using optimization theory, we computed ideal substitute time point nuclear EPR for According to actual situation in production, corresponding incentive suggestion were put forward promote substitution between clean-and-low carbon dirty-and-high order...

The improvement of energy efficiency in electric power supply and demand system is involved production, distribution, using, which a complex engineering system. Using the theory we studied optimization overall resources After feedback mechanism analyzed system, thought that only by construction user response subsystem can improve Then, some feasible suggestions for responding were put forward.

VSC is a league made up of some software firms different advantages and resources aiming at common developing tasks or relative services. the result cooperation based on it’s cooperative efficiency. This article tries to find out compute those primary influence factors VSC’ operation through mutiple statistical method RST, then suggestions are given.
