Recent Power Transformer Technology
Power transformers are essential components of substation equipment for the efficient and stable operation of electric power systems. There is demand for transformers with lower price and higher reliability. In addition, depending upon the onsite conditions, such as narrow roads, mountainous areas or highly congested urban areas, harmony with the surrounding environment is required throughout s...
متن کاملRecent Developments in Compound Semiconductor Microwave Power Transistor Technology
This paper addresses the state-of-the-art in microwave and millimetre-wave power transistor technology. The relative performance of microwave power transistor technology from 1 GHz to 60 GHz is reviewed. The fundamental technological drivers in the design of microwave compound semiconductor power transistors are discussed as the basis for developing optimum designs. A new high yield power GaAs ...
متن کاملRecent Technology for Reusing Aged Thermal Power Generating Units
For the continuous operation in another 20 or more years from aged thermal power generating units that have already been operated for 30 years, Fuji Electric has replaced a two-cylinder reheat type turbine with sophisticated single-cylinder reheat type turbine, were reused the existing foundation and nearly all the auxiliary machinery as counter-measures of life prolongation of the plant. By re...

15 صفحه اولModifying Modern Power Systems Quality by Integrating Grid Computing Technology
The need for reliable, powerful, and clean power generation in power systems is becoming more importance. This need requires geographically-distributed power systems to be integrated as a single entity where among the main features of this integration are large data base and computing intensive. Hence the current power systems are not able to handle this huge datasets required for that integrat...
