optimal solution between four different technologies (CCAIS, DCB, HIS, GIS) in
substation design. Moreover it consists of sensitivity analysis module on important
decision parameters such as land cost and weight of attributes. This new solution for
space saving of AIS substations and the developed algorithm for selecting the optimal
alternative is proposed to Tehran Regional Electric Company which is the greatest
utility in electrical power system in Iran. The results of this project have been proposed
in Tehran Regional Electric Company (TREC).
Project Results:
• Design and preparation of single line, layout and section drawings of
conventional compact AIS (CCAIS) solution with single busbar arrangement for
urban 63/20 kV substations.
• Design and preparation of single line, layout and section drawings of innovative
compact AIS (DCB) solution with single busbar arrangement for urban 63/20
kV substations.
• Development of an algorithm for optimal solution selecting method among four
technologies (CCAIS, DCB, HIS and GIS) for compact urban 63/20 kV
substations based on technical and economical evaluation.
Project Documentation:
• Line and Substation Department; reports on " An investigation about compact
substations in Tehran Regional Electric Company " and software package,
Transmission & Distribution Research Center; Niroo Research Institute; 2010
and 2011.
