Abstract

A power system test system is designed using PSCAD/EMTDC software for transient analysis, which can be specifically used for transient studies with Distributed Generators (DGs) or this system can be easily developed as a Microgrid test system. The model is developed based on a section of a practical power system that is Kukuleganga area of the Sri Lanka power system. This includes 132kV transmission system, Kukuleganga hydro power station, five grid substations with 33kV distribution buses and DGs. The developed model is verified through comparing the actual fault data obtained from the Ceylon Electricity Board, Sri Lanka with the results obtained from the developed PSCAD/EMTDC model. The Discrete Wavelet Transform is used to identify the degree of accuracy in verification of the model. The test results are demonstrated for both current and voltage waveforms.
