Meter Data Management System(MDM)
-
System Overview
-
The electricity metering data automatic acquisition has being more and more popular since the early 21st century. The application scope and effects are keeping expanding those covers power generation, transmission, distribution, utilization and any other sections for both civil and enterprise, During “12th Five-Year Plan”, MDM system in China has been created one after another to realize electrical meter data acquisition securely, metering management intensively and application standardized, to reach the goal of ”cover all meters, collect all data, control all by expenses, to support bidirectional interactive smart grid, to improves marketing management of grid companies.
