This paper presents the determination of insulation coordination for phase-to-ground switching over voltages by a practical method in which effect overvoltage waveshape, especially impact time to crest on strength is considered. work carried out world’s first 1200 kV transmission line modelling it PSCAD.

Ferroresonance is a nonlinear dynamic electrical phenomenon, which frequently occurs in a power system that comprises no-load saturable transformers, transmission lines (or cables) and single-phase switching with three-phase supply. Common characteristics of a nonlinear system are multiple equilibrium points, limit cycles, jump resonance and subharmonic generation. This paper presents an extens...

This paper presents an improved control strategy for parallel inverters so as to better manage power sharing among the distributed generation units in a microgrid. The proposed control strategy combines both power and voltage control schemes implemented on the voltage source inverters which are used as power electronics interface systems for conversion of power generated by fuel cell and photov...

The principle of the traveling wave based differential protection for bipolar HVDC transmission lines is proposed in the paper. Unlike the traditional current differential protection, the quantity of current is replaced by the quantity of the traveling wave for comparison. The traveling wave at the remote end is transferred to the local end for comparison to the local traveling wave. For the bi...
