Data Processing and Management Clausole campione

Data Processing and Management. The system software will be based on an industry standard software package with performance and quality proven in other similar RTMSs. All data acquired or calculated by the RTMS system will be stored in the SCADA database system. The RTMS will be capable of providing storage for selected aggregated historical data for a period of at least 10 years on line (hard disks or SAN) and for an unlimited time on magnetic tapes or similar technology. The local substations will be equipped with a data storage system capable of storing data from the field equipment even in case of failure of the communication between the substation and the Control Centre. The local substations' storage will be capable of retaining a minimum of 200 hours of unprocessed information, without operator attendance regardless of the sampling regime in force. After connection to the Control Centre is re-established, the local substations will transmit buffered data to RTMS so that the database of the RTMS holds a complete series of data regardless of any communication breakdown period less than 200 hours. All data collected by the RTMS field equipment will be tagged and time stamped where first stored, so that data always can be traced back to a specific time and location. All data recorded will be time-stamped in accordance with the system clock. The RTMS will have a clock function capable of keeping permanent synchronisation with an external clock source to within +/- 10 ms. The RTMS will be responsible for keeping all attached field equipment synchronised to the RTMS clock with similar accuracy. All real-time data will be stored in a short term storage within the RTMS system to allow internal RTMS assessments/calculations to be made in real-time. The RTMS system will stream a live data-feed to the SCADA database thus making data available to subscribing functions like the SHMS. Alarms acquired from field equipment data communication equipment or generated in the RTMS server will all be transmitted to SCADA in real-time.
