"A Novel Algorithm for Determining the Exact Location of Switched Capacitor Banks in Distribution Systems "
by H. Khani, M. Moallem, S. Sadri
Proceedings of the Transmission & Distribution Conference & Exposition: Asia and Pacific, October 2009

In this paper, a method is proposed for determining the exact location of switched capacitor banks in distribution systems. The method consists of two steps. In the first step, the technique is based on measurement of voltage and current transients created by capacitor switching. The hypothesis states that: The slope of voltage and current transient wave forms created by capacitor switching immediately before and after the switching instant will have opposite polarity for monitoring the location at line and branches feeding the capacitor and identical polarity for monitoring the location at other part of the power networks. Wavelet transform techniques are used to determine the exact switching instant effectively. Simulation is done by EMTP. In the second step, using the exis- ting capacitor switching transient data, a method based on linear circuit theory is used to estimate the exact distance of switched capacitor bank from the monitoring location and it is simulated with Matlab Software. The method is valid for both wye and delta configured capacitor banks. This proposed method is applied to the IEEE 37-bus distribution system.
