The aim of the project consists in the development of a distributed system for power quality improvement. The project is focused on two very important power quality parameters, i.e. higher harmonics in current/voltage waveforms and reactive power delivered by supplying network. These two negative phenomena cause the increase of losses in the power system and simultaneously the decrease of the system power factor. As a result of the project, devices used for reactive power compensation and filtration of supplying current higher harmonic as well as a software for optimal choice and placement of these devices in the power system will be developed. The elements of innovativeness are included in algorithms implemented in the proposed software as well as in devices used for improvement of selected power quality indices. The research under this project should allow to develop algorithms for optimal placement of devices used for compensation and filtration taking into account the installation cost and the estimation of the future financial (lower losses and penalty fees) and quality profits. The novelty of the proposed solution comes also from the main target market for the products developed in the project. The proposed solutions include devices in explosion-proof enclosures required by coal and chemical industries. The other novelty aspect concerns higher harmonic filters with hybrid topology. The proposed system is a combination of software and technical solutions which should lead to decrease of losses and improvement of both working conditions of electrical equipment and power system stability and safety. The economic aspect of the proposed solution is very important. Application of compensators and filters will result in measurable economic gain obtained by lower electrical energy bills, reduction of penalty fees for too high active power consumption and lower load of power system.
