Automatic Meter Reading for Sub-Stations & Consumer Meters By : Rajesh Sharma Director RS IT & Power Hub Pvt. Ltd. About US Our expertise lies in Integrating Technologies for the people • Strong domain knowledge in real time data applications like control and automation software (SCADA), Plant Intelligence solutions, Manufacturing Execution Systems (MES), Batch Plants automation and Interfacing plant data to ERP systems. • Exhaustive knowledge of complex control system hardware and software. • Expertise in Device driver development, latest IT tools, databases and report generation software. • Hands on- field experienced people. • An ISO 9001:2000 Certified organization. • 'India Advantage': high-quality low-cost services AMR (Automatic Meter Reading) Every Utility / Discom is fighting to find a solution for this problem PROBLEMS • Protocol • Communication Ports • Existing Meters • Technology • Implementation Time • Few More PROBLEMS • Protocol No common, Standard / open protocol is available in the energy meters available nor the meters which are being purchased. Standard Protocol :• PACT (Multi dropping not possible) Open Protocol :- • Modbus ( Values are integers have to use multiplying factor at software end) • IEC 101 (No known meter available) PROBLEMS • Communication Port No common type of port is available in the energy meters available nor the meters which are being purchased. The mixture of Optical, RS-232 and RS-485 is available and none has the record of the ports. Recommended :RS-232 for the meters installed individually RS-485 for the meters installed in groups (Substation, Group Metering) PROBLEMS • Existing Meters As these meters vary in technologies, makes, Protocols, communication ports, etc. which creates a difficult situation for AMR implementation teams. Recommended :Request the manufacturer to take back old meters and replace with new ones, as in many a cases it is only firmware up-gradation or minor modification. PROBLEMS • Technology As these meters vary in technologies, makes, protocols, communication ports, etc. which creates a difficult situation for AMR implementation teams. Recommended :Request the reshuffle / change energy meters to create the situation for the AMR supplier to opt. one technology / methodology for the system. Example : Change all substation meters with the ones having RS-485 port & Modbus protocol. PROBLEMS • Implementation Time As these meters vary in technologies, makes, protocols, communication ports, Multiplying factors etc. which creates a difficult situation for AMR implementation teams. Recommended :Request the reshuffle / change energy meters to create the situation for the AMR supplier to opt. one technology / methodology for the system. This will reduce the AMR implementation time drastically. PROBLEMS • Few More • AMR Technologies (Which ?) • Central Control room Softwares (Scalability ?) • Audit Reports (What ?)
