This paper proposes an efficient shunt active filter for harmonic reduction in hospital building electrical installation. Harmonic installation in distribution system is caused by non-linear electrical loads, especially those containing coils, such as air conditioners, pump machines, fans, and others. Harmonic can cause excessive heat in a distribution transformer that supplies an electrical installation in a multi-storey building. This heat is a power loss and has the potential to shorten the life of a distribution transformer, so that efforts are needed to reduce harmonics. One effective method to reduce harmonics is to use active filters. In this study, a shunt active filter application in the electrical installation of a hospital building was carried out. The results showed that the filter was able to reduce harmonic currents significantly, so that the harmonic threshold was still in accordance with the IEEE standard.

Ultimate Objective

Comparison of Multiple Carrier Disposition PWM Techniques Applied for Multi-Level Shunt Active FilterThis work presents the simulation of a shunt active filter using seven-level cascaded inverter. The ultimate objective is to bring out the influence of multiple carrier level shifted PWM techniques on the performance of a shunt active filter. Classical disposition PWM techniques such as PD, POD and APOD have been used to generate the gating signals for the inverter active switches. A comparison is presented to substantiate the effect of these techniques in filtering. The comparison is made from the perspective of reduction in THD of source currents after filtering. For compensation current extraction synchronous detection method has been used. The harmonic reduction is achieved in source currents as well as source voltages.
