Traction power supply equipments are the core part of the high-speed railway, so the maintenance of the power supply system is crucial for the security of the railway. Based on the research on the durable years of the traction power supply equipments, this paper puts forward the model of testing the traction power supply equipments of the reliable high speed railway. Some practical researches h...

In a distribution power system, vividly in a deregulated market and restructured environment, blind time based maintenance of all the distribution equipments is neither affordable nor economically justifiable. Moreover, an acceptable level of system reliability is an indispensable criterion for the successful operation of a power distribution system. To enhance the cost effectiveness of distrib...

The platform has flexible implementation; commom construction; strong ability of modular, expansibility and portability; easy to improve and extend; suitable for testing and verifying evolving LTE-Advanced system. With the platform, we conduct real-time experiments for investig...

Power supply in the 21st century is facing more and more challenges, e.g., environment protection, energy shortage etc, such that the techniques related to power supply imminently need to be promoted. Complying with the development of green and lowcarbon economy, the concept of Smart Grid has been proposed. By and large, Smart Grid may be regarded as an important application of the techniques o...

We propose to define a volume around cognitive radio equipments, typically terminals, called the ”Sensorial Radio Bubble” or SRB, the diameter of which is at the scale of the sensing possibility of the equipment. The SRB gives communication equipments the ability to explore the radio environment in order to provide knowledge about the spatial and spectral environment, and some context awareness...

Despite efficient carbon monitoring system and the commercialization of battery technology for intra-port transportation, port management are found not adopting these environmental yet costly equipments. Port authority who regulates environmental policies lacks leverage to impose tangible reduction on emission through concession. This model integrates sustainability into port equipment expansio...
