Abstract :
In this paper, two technologies are used to mitigate transients caused by capacitor switching in distribution feeders. The basic concept of capacitor bank switching transients and its mitigating techniques is presented here. The MATLAB /SIMULINK software is used to simulate the energization of a controlled capacitor bank in a specific substation feeder, with and without employing mitigation devices. Mathematical computations of quantities such as peak transient voltages, currents, and frequencies are provided for each case. These values are compared to the values obtained from the simulations of each case study.
