Abstract
This report is part of the requirements to achieve the master of engineering M.Eng. Degree. It presents a study of different power filter topologies used to compensate the customer-generated disturbances caused by a non-linear load connected at the point of common coupling (PCC).
Chapter one gives a brief introduction to the sources, effects and conventional solutions for harmonics and power factor
Chapter two presents a study of different power filter topologies used to compensate the customer-generated disturbances caused by a non-linear load connected at the point of common coupling (PCC). The advantages and drawbacks of each topology are analyzed under different conditions. Finally, it is proposed a criterion for the selection of the most appropriate topology depending on the type of harmonic-producing load.
Chapter three presents a shunt active power filter application mainly for current harmonic elimination and fixed reactive power compensation. Effectiveness of the system is confirmed by the simulation results obtained from software prototype in chapter four.
A dynamic model in MATLAB/SIMULINK comprising the shunt active filter is developed in chapter four. The model starts from electric load & source to the APF including electrical measurements for voltage and current, 3 phase rectifier, control system, 3 phase inverter and the interfacing inductance. The model is used for experimenting for the development of a method that reduces voltage harmonics in the internal electrical network using the inverters. A method based on shunt active filters is developed and proved useful for several load types.
A dynamic model comprising the wind farm is presented as an application of APF in chapter five, from the DC-link of the wind turbine converters to the transmission grid. The model uses the mentioned wind farm as basis and common characteristics include; turbine topology and size, voltage levels and cable lengths
