Abstract

This paper presents a new method for locating the source of capacitor switching transients using the complex wavelet-based energy approach. By using the complex wavelet transform, the transient power at the monitoring point is first calculated and the complex wavelet energy is obtained by integrating the transient power. From the wavelet energy plot against time, a change in wavelet energy from an approximately zero to a negative value indicates that the transient source is in front of the monitoring point. On the other hand, a change in wavelet energy from an approximately zero to a positive value indicates that the transient source is behind the monitoring point. To verify the proposed complex wavelet method, simulations by switching the capacitors using the PSCAD/EMTDC program were simulated for generating oscillatory transients. Comparisons were also made in locating the transient source using disturbance power and disturbance energy technique. Simulation results prove that the complex wavelet-based energy approach is more accurate than the disturbing power and disturbing energy method in locating the source of capacitor switching transients in a power distribution system.
