THD Analysis in 3ph, 2-bus Distribution Network with RL-RC loads &UPQC

Abstract

Necessity of a distribution model is to withstand the customer requirements for energies after gaining huge electricity from transmissions and substation networks. Many of the networks are implemented to match with the supplies reliability case.Switching, controlling and protection equipments are introduced to enhance the distribution systems performance. Most of the power quality improvement devices are introduced in power system network to deal with the issues which are takes place at either ends of the power system network. This work mainly focuses on 3ph-2bus model with RL-RC loads and conditioner device. The conditioner device introduced here is to enhance the system response interms of reduced Total Harmonic Distortion (THD) levels, improved real-reactive coefficients with various load models.PQ analysis is done with both the load combinations to obtain the enriched response of a three phase two bus system.
