Measurement of Ground Potential Difference at Power Substations
IEEE Power Engineering Review, 1991A method of obtaining a record of ground potential difference (GPD) values in substations where a remote ground and an oscillograph are available is presented. Typical recorded values of GPD range from under 100 V to a maximum of 450 V RMS. These measurements suggest that the values used for ground mat design should be considered by the telephone ...

Fuzzy Control on Voltage/Reactive Power in Electric Power Substation
2009A fuzzy method using in voltage and reactive power control in electric substation is proposed based on the improved 17 Areas Method derived from 9 Areas Method. A simulation model is founded with fuzzy control rules used the Matlab simulink. The simulation results indicate that voltage of the model with fuzzy control is less fluctuating and much ...

Computer vision applications in power substations
2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies. Proceedings, 2004Computer vision is a quite mature technology nowadays and it is very useful for power system monitoring applications. In this paper, some computer vision applications in a power substation will be reported. The system implemented is able to conduct automatically intruder detection, fire alarm zone detection and substation meter reading.
