Tiivistelmä
A continuously increasing amount of data is gathered from the distribution network. The increased amount of data offers new possibilities to be utilized but requires more sophisticated processing to be applied as well. This data consists mainly of different alarms, status indications and measurements. The target of this thesis was to study the process data and its possibilities for proactive network management.
The study for the present state of process data utilization was carried out from two different perspectives. At first, an exploration was made to the available process data and the processes exploiting it. The studied data sources were substations, automated disconnector stations, remote reclosers and smart meters. The study was complemented by including the user perspective with interviewing the personnel of Elenia. From the interviews, several visions for the improved process data utilization were encountered. These were refined to the functionalities of a novel Proactive Network Management System (PNMS) concept by studying the required initial data and some other boundaries. The functionalities will form a guideline for the system-driven development of proactive network management in Elenia.
More thorough analysis of the new functionalities revealed that it would not be reasonable to implement all of these into a single system; a novel nor an existing one. Some of the functions could be implemented into existing systems with little effort. Some of the functionalities instead require data from multiple locations and may not fit in any of the existing systems. Thus a need for a novel system was verified. Each of the functions requires still more careful evaluation before implementing them into practice. The features of this novel system were also discussed in general.
Finally, two of the discovered functionalities, repetitive reclosing analysis and the handling of disturbance records, were studied in more detail. The former represents a functionality which could be implemented in the Distribution Management System (DMS) in use at present. Next, a more detailed specification should be made with the software vendor. The latter would enable the multiple functionalities of which the improved fault analysis was studied the most. To have these functionalities implemented in practice, further research is needed with actual records to verify the potential of each function before rushing into system development.
