The Research On Function And Application Of Wireless-access Intelligent Low-voltage Disteibution Terminai

With the current electricity reform the development of science and technology to themarket in the direction of deepening the electricity network which promotescommunication between system and user, so that the increasingly close relationshipbetween the two.Grid user requirements increasingly high level of power quality. To meetthis requirement, the number of distributed generation sources is more and more, whichexceeds the current electricity network could afford at this time to launch a "smart grid"concept.Grid of the future will necessarily toward "smart grid" direction. Smart grid powersystem is the foundation of this smart grid,it can promote from generating electricity,power transmission, distribution and energy to save energy, the use of two-way flow ofelectricity situation, you can make electricity production, transmission, use has beenoptimized. As a smart grid smart meter data collection terminal, in the smart grid plays animportant role. It can not only capture the raw data can also charge and tariff informationdisplayed in real time, the user and the power to promote a two-way information exchangebetween departments.Adapt to smart grids and electricity management model development needs,based onAMI model to research and develop a mobile communications network using3G/4G access,setting bi-directional energy metering, power quality monitoring and power protectionfunctions in one intelligent low-voltage distribution network terminals for power users witha full range of power management, intelligent protection and interactive control. Theterminal uses a modular structure, with good hardware and software scalability, through thenetwork for remote configuration and software updates can be achieved without changingthe hardware capabilities of the expansion and power management mode conversion. Thisnetworking intelligent power distribution terminal has significants on the development ofsmart grid, improving power quality, enhancing power management, reducingadministrative costs, promoting energy conservation and scientific and rational allocation.
