During the last decade a lot of efforts have been put into promoting the access to electricity to those millions of people living in rural un-electrifled areas of underdeveloped countries. Despite the huge potential market of new consumers, the progress of electrification rates in such areas is very limited. Besides evident economic constraints, also lack in appropriate and replicable technical solutions...
This document describes the usage and meaning of Energy Management Systems (EMS), applied both for utilities and end customers as a mean to supervise electricity usage and obtain energy savings. The approach also does a benchmarking on existing systems and appliances, together with the increasing usage of EMS in the newest smart grids.
From fields of Secondary system construction of substation preconditions, engineering, equipment installation, and prepare EMS joint debugging, wireless emergency communications systems, acceptance of work and relay protection measure differential circuit phase, we discusse the substation of quadratic system engineering organization construction optimization. Practical experience of the substation...
From its principle, system structure, main function and realization method, measurement information online intelligent test and evaluation system in Changchun grid is introduced in this paper. The correctness and effectiveness of the system are proved by actual operating experience.
A method of data connection by a digital simulator and EMS system is provided in the paper, and integration with off-line data and EMS real-time data can be operated automatically. On present situation, almost all of analyses of electric power system adopt off-line data which is much more onerous input in computer by hand, and the result can not accurately describe the actual condition in operation...
With the continuous advancement of computer input technologies, more input types could be chosen and used when designing the human-computer interface of EMS. In this premise, establishing the quantitative evaluation methods of human computer interface's input-side of EMS is required. This paper presents a quantitatively evaluation method of three design elements, namely operating efficiency, cognitive...
