The power system training simulation software, exist in the market, emphasis on the network structure and flow calculation without the local details or equipment operation, or focus on one or two substations, but ignoring the power of the substation. With more and more complex structure of the domestic power grid, and increasing scale of power, the existing power system simulation software cann...

In this paper, a power consumption model for both macrocell and microcell base stations is proposed. This model is validated by temporal power measurements on actual base stations and an excellent agreement is obtained. Furthermore, the power consumption’s evolution during the day is investigated by means of these measurements. The energy efficiency of three different wireless technologies is c...

In order to solve the shortcomings of single air source heat pump, solar pump and double one electric multi-stage dual a integrated is designed. The heating capacity COP same under three different operating conditions were simulated, simulation results compared analyzed. show that system are higher than those system. With continuous decrease outdoor temperature, advantages wind tunnel hybrid mo...

This paper presents an application designed to train electrical sub-station operators by means of a virtual reality environment. The application allows full viewing of any of the sub-stations in the power supply network. With the appropriate hardware (HMD, 3D mouse and tracking systems) it is possible to navigate into the virtual world and interact with the elements. Each of the sub-station com...
