A study on the performance of 10kW Grid-Connected Photovoltaic Power Conditioning System with characteristics variation in inductor core materials Lee, Kyoung-Jun

Grid-Connected power conditioning system (PCS) is widely used for distributed generation system. In Grid-Connected PCS, the LC filter is essential to reduce the current harmonics injected to the grid. In this paper adequate inductor core materials are selected to analyze the performance of 10 kW Grid-Connected Photovoltaic (PV) PCS. Core materials can be classified into three groups: power core, sheet core and ferrite core. For the experiment, Fe-3%Si core, Fe-6.5%Si (Super core) and Mega Flux core were chosen as a filter inductor core. Optimal condition for each inductor core is determined by the efficiency and THD.

Three-phase four-wire electrical distribution systems are widely employed in manufacturing plants, commercial and residential buildings. Due to the nonlinear loads connected to the distribution system, the neutral conductor carries excessive harmonic currents even under balanced loading since the triplen harmonics in phase currents do not cancel each other. This may result in wiring failure of the neutral conductor and overloading of the distribution transformer. This paper proposes a reduced rating active power filter to suppress neutral current harmonics in three-phase four-wire electrical distribution systems. The proposed scheme employs a single-phase inverter connected in series with the neutral conductor and a -Y transformer connected in parallel with the load. The proposed active filter eliminates neutral current harmonics while it does not affect the fundamental current due to unbalanced loading. The VA rating of the inverter is significantly reduced since only fundamental current due to unbalanced loading could flow through the inverter switch. The experimental results on a prototype validate the proposed control approach.

18.1 Introduction Uninterruptible power supply (UPS) systems become more and more important due to the growing critical loads, such as telecommunication systems, computer sets, and hospital equipments. In the last few years, an increasing number of publications about UPS systems research have appeared, and, at the same time, different kinds of industrial UPS units have been introduced in the market. Furthermore, the development of novel energy storage systems, power electronic topologies, fast electrical devices, high-performance digital processors, and other technological advances yield new opportunities for UPS systems [King03, Bekiarov02].
