Energy Management and AMR systems | Prepaid Energy
Energy management and AMR systems are used in Shopping malls. There are two main system type. Billing and prepayment. The prepayment systems will be explained with its some advantages in this article.
In terms of Energy Management and AMR Systems, the prepayment systems are the most preferred energy management systems by shopping malls. Payment advantages and load control options are very useful features. General communication infrastructure is same with the others. In this case, the differences are meter types and software options.
As you now, within the context of Energy Management and AMR Systems, Aktif Mühendislik use Iskraemeco energy meters in prepayment systems. Mx372 and Mx383 series are used mostly. These energy meters can be programmed according to prepayment system. The credits can be load in these meters. When this operation any magnetic card usage not needed. The credit loading to meters is done via communication line. With their internal circuit breakers the load control can be done. With this option the customer energy can be disconnected when the administrative wants. These energy meters not only read energy. They can measure main electrical parameters like voltage, current and power factor. By the way another advantage of these meters in terms of Energy Management and AMR Systems, with their m-bus master options, the system can read over energy meters to m-bus communication featured meters like water or calorimeter.
RS485 cable system is preferred generally. But according to the Shopping Mall needs this can be changed to PLC or GSM/GPRS. In RS485 cable system, bus connection type is used. There are RS485 communication lines. Every communication line can have up to 31 energy meters and these line distances can be maximum 1200 meter.
The main PC has Actwin Smart energy management software. This software completely created by Aktif Mühendislik Engineers.
