Standard EMDAS metering Panel consisting of duel independent EMDAS systems. Pulse counting input modules expandable to accommodate site specific energy pulses requirements. Software pulse filtering and de-bounce to count the 80ms energy pulses Digital output module used for system cross checking and Alarm generation to station DCS.
All pulse data is stored within the EMDAS PLC controller card with 24hr rollover registers for hourly energy data backup that can be reloaded in case of communication failure – operating completely independently from the PC data server.
Networked DLMS and Modbus communication directly to the Energy meters allows for the retrieval of energy data as stored by modern meters.
The Dot Net based EMDAS server software running on the PC continuously monitors energy data on the controller storing current and hourly values into the Microsoft SQL database. Automated FTP file transfer of hourly values is generated and transmitted on the ESKOM LAN to the National Control server.
Automated data verification by software and hardware hand-shaking and data comparison between the two EMDAS systems continually verifies data and System integrity between Main and Check energy meters and EMDAS 1 and 2 data generating System. Audit and Alarm data logs into the SQL server database. Hard-wired alarms are provided to the DCS / Station SCADA.
Hourly and Daily Energy reports can be viewed and printed. Data storage is only limited by hard disk space and is therefore basically unlimited.
Hard wiring of the input Energy pulses is based on a centralized EMDAS connection to metering panels by UVG cables.
Remote users gain access to the EMDAS Web server via the ESKOM LAN.
