Distribution automation in Finland. Final report of the research programme 1990-1992

Technical Report:

Abstract

The report comprises a summary of the results of the research programme on distribution automation, conducted in Finland 1990-1992, under the leadership of the Technical Research Centre of Finland. For network automation, the most important project was to develop new methods for calculational fault location. The main emphasis was given to the location of single phase to ground faults in networks with high impedance grounding. For urban cabled networks, the feasibility of distribution transformer station monitoring was studied. The main functions considered were transformer load monitoring and remote reading of the fault indicators located at the transformer station. For optimizing the extent of network automation, i.e. remote controlled sectionalizers and the remote reading of fault indicators, some planning models were also proposed. For distribution network state estimation, models were developed, which combine the real-time measurements to the statistical data of typical consumer groups. As an application of the models, the estimation of distribution transformer loads was studied. For load control, a computerized optimization model was developed, by which the efficiency of peak demand reduction can be increased. In addition, the sensitivity of load control to various parameters was studied. The effect of distribution automation to the network planning was studied  More>>

The effect of distribution automation to the network planning was studied by case studies; especially the dimensioning of reserve connections was discussed. Also the requirements which may be set by future distribution automation systems for computer and data transmission systems of utilities were estimated, in order to define the needs for future research and development work}
