In order to evaluate operational state of distribution network and facilitate the economic dispatch considering distributed generators, operational evaluation system of distribution network considering distributed generators is proposed. Furthermore, complex evaluation indicators of safety, power quality and economy are defined to evaluate distribution network with distributed generators as well....
A nondestructive and contactless screening method for selected lubricating grease stored in common plastic box has been examined using the terahertz (THz) time-domain spectroscopy. The THz wave has been transmitted through the commercially available lubricating grease in polystyrene filters. Greases have unique spectral features in the THz range, and the differences in the absorption coefficient and...
In this paper, an on-line voltage stability index based on wide area measurement and the ?? equivalent branch model is expound, the physical meaning of the index, namely the virtual active margin index (IVAM) was propose. Through the simulation of the IEEE14 standard example, found the problem of IVAM-we propose a novel on-line voltage prediction index considering the trends in IVAM for real-time...
