Abstract

Power engineerings have become increasingly concerned about power quality due to the growing usage of electronic devices. The primary cause of declining power quality is the presence of high levels of harmonics. The harmonic itself happens due to the non-linear loads which here is induction furnace, so that distortion are produced in the sinusoidal waveform. This paper studied about the harmonics analysis of the 33 kV Abuja Steel Mill Feeder modeled as a harmonic source using measured data. The continuous harmonics without mitigation would cause problems to the other electrical equipments such as transformers, motors, and cables. These problems would likely lead to the economic losses to the company. Therefore, an harmonic analysis and harmonic filter design in 33 kV Abuja Steel Mill Feeder so that can reduce the harmonic level on the electrical system. By having harmonic analysis and harmonic filter design, it can reduce the harmonic level and losses of the company, also ensure the system is working properly and safety. To design a proper harmonic passive filters, it needs a accurate calculation and precise placement of the filter also. The brain of designing a proper harmonic filter is how to determine an accurate magnitude of Qvar that need to be compensated to the system, so that the filter can work properly. The writer using two different methods in order to indentify how much magnitude of Qvar for each filter. By using those two methods, the writer found out that the first one is more reliable than using the second. Because the value of THDv and THDi by using first method is showing better value and it is good according to the IEEE 519-1992 Standards. The writer is using ETAP 12.0 for doing simulation of harmonic analysis and filter design.
