Electric power quality problem has become an important problem in modern society, which effects industrial production and product quality, etc. So, we urgently need monitor and analyze electric power parameter to solve electric power quality problem. In this paper, we design a kind of electric power parameter detection system based on visual instrument (VI) technology, etc. System uses voltage/...

Power system reliability and continuous electric power supply without downtimes or with a few as shorter as possible interruptions are basic for financial success in today's power market (EN50160). So, modern customer oriented relationships and efficient electricity service have to be included in nowadays power system management. Reliability and availability are concept very close to electric p...

Models of propulsion motors, generators, gas turbines, and power converters are used to determine weights and volumes, evaluate designs, and predict performance of power system components for all-electric navy ships. The finite element analysis method using 3D CAD models is used to validate designs and predict performance under prescribed constraints that simulate realistic operational conditio...

Most of the present day electric scooters are equipped with a voltage-driven DC motor powered by four 12-volt leadacid batteries and a hand-lever accelerator operated by the rider to control their speed. Because of the nonlinear battery discharge characteristics and different driving behaviors of riders, it is not easy to tell how much electric power remaining in the battery and how far the ele...

The electric power system is an important infrastructure that plays the important role in the economical status of a nation. It is, therefore, very important and useful to design a green energy distributed power system .This paper presents the concept of power management strategies of a green energy distributed power system .The green energy distributed power system is one way to assure self-he...

In this new era electric power has become a fundamental part of the infrastructure of modern society, with most of daily activity is based on the assumption that the desired electric power is readily available for utilization. In the near future, electric supply to houses, offices, schools and factories is taken for granted. The complex power distribution system provides the required electricit...

In Japan, the Great East Japan Earthquake and the subsequent tight power supply, introduction of a feed-in tariff (FIT) scheme, and power system reform have caused dramatic changes in Japan’s power systems. These changes led to acceleration in the introduction of solar power and other renewable energies, an increase in the number of the new power suppliers, and reinforcement of interconnections...
