This paper presents modified SRF Three phase three wires shunt active power line conditioner system, for three wire and four wire systems in which three single phase loads are fed. In power system Poor power quality sources are raised from two categories: (i) Non-linear loads, electrical components and equipments (ii) Subsystems of transmission and distribution systems Quality degradation of electric power mainly occurs due to power line disturbances such as impulses, notches, voltage sags / swell, voltage and current unbalance, interruption and harmonic distortions. The electric power quality has become an important part of the distribution power system. Harmonics are the primary cause for the poor power quality of the distribution system. To improve the power quality both input currents and output voltages are simultaneously controlled to be in phase with respect the input voltages. Therefore, an effective power factor correction is carried out. Operation of a three-phase phase-locked loop (PLL) structure, used in the line interactive UPS implementation, is presented. The control algorithm using SRF method and modified SRF method active power flow through the UPS system are described and analytically studied. Design procedures, digital simulations and experimental results are presented in order to verify the good performance of the proposed three-phase line interactive UPS system..
