2013. — 8 с.One important feature of the digital technology of today is the immense storage of information. In locally installed IEDs, event logs as well as fault (disturbance) records are available for analysis. These IEDs are numerical protection and control relays and fault recorders. The Power quality meters deliver power quality information. All these data sources can be used for monitoring of the e.g. pri-mary equipment, as all this data is available locally today. This paper shows how data from various sources, when integrated into an intelligent system, has real value for the user.
Siemens offers with SIMEAS SAFIR, an information system which gathers precise monitoring data, offers easy to-use web applications to asset managers, network control operators, protection ex-perts and network planners. Due to the numerous measurements that SIMEAS SAFIR can collect in nearly real time, it can complement the picture provided to network operators by the SCADA system. Network analysis based on measurements neatly complements the calculations that rely more heavily on power system modelling.
