Unified Power Flow Controller (UPFC) has a promising effect on controlling the characteristics of the power system operation. During the contingency outage cases, the transmission lines are overloaded and the buses are subjected to voltage violations. Unified Power Flow Controller (UPFC) has both shunt and series controller effect inside its frame. This option gives the UPFC the power to control the...
De-icing schemes and operations for overhead power line in 10kV, 66kV and 220kV networks based on shunt capacitor over-compensation method are proposed in this paper. This novel de-icing method is based on characteristics of sinusoidal AC and theory of shunt capacitor over-compensation. By utilizing 10kV capacitor bank, which is installed as standard apparatus in substation, reactive current can be...
Traveling waves recorders (TWRs) are used to accurately find the location of different faults in power transmission networks. These recorders are installed at few high voltage buses where current traveling waves (CTWs) can be extracted. The CTW signals' time delay of the initial wave is recoded at each TWR. In this paper, the minimum travel time of the CTW has been calculated considering Dijkstra...
