|In this paper, a compensation strategy for a low- voltage network comprises a power factor correction capacitor and non- linear loads connected to the same load-buss is investigated. The loads in the low- voltage network can be classified, from the harmonics point of view, into harmonic current producing loads, harmonic voltage producing loads and harmonic sensitive loads. The compensation in the low -voltage side of a power network is more reliable, efficient, economic and straightforward. The idea here stems from the fact that when applying a pollution treatment for a river, it is not practical, in all cases, to establish a treatment unit across the river. The more reliable solution is to clean and purify those outlets discharging into the river individually. If this concept could be generalized in industry, it is logical that the cost of applying the proposed compensation strategy to an industrial unit would not be comparable either to the price of the production line or to the penalties paid to authority on the long run. In the next sections, the proposed strategy will be clarified through analysis, design and simulation using a shunt active power filter.
