Abstract
In recent years, shunt hybrid active power filters are being increasingly considered as a viable alternative to both passive filters and active power filters for compensating harmonics. In literature, their applications are restricted to balanced systems and low voltage applications and therefore not for industrial applications. This paper investigates the performance of a modular cascaded multilevel inverter based Shunt Hybrid Active Power Filter (SHAPF) for reactive power compensation and selective harmonics elimination under distorted/unbalanced grid voltage conditions in medium voltage levels. In the proposed control method, reactive power compensation is achieved successfully with a perceptible amount and the performance results of harmonic compensation are satisfactory. Theoretical analysis and simulation results are obtained from an actual industrial network model in PSCAD. The simulation results are presented for a proposed system in order to demonstrate that the harmonic compensation performance meets the IEEE-519 standard.
Highlights
In recent years, high power equipment has been employed in industrial applications due to the megawatt power level for many medium voltage applications
The simulation studies are carried out using PSCAD/EMTDC, aiming to evaluate the effectiveness and correctness of the control strategy used in the Shunt Hybrid Active Power Filter (SHAPF) under unbalanced/distorted grid voltage
A new control approach is investigated in order to ensure the ac current shaping, compensate the reactive power and regulate the dc voltage for a three phase modular cascaded multilevel inverter based shunt hybrid active power filter
Summary
High power equipment has been employed in industrial applications due to the megawatt power level for many medium voltage applications. Due to this condition, multilevel power converters are to be used as an alternative solution in medium and high voltage applications. Multilevel converters have the ability to increase the output voltage without raising the voltage rating of switching components. They are preferred to connect to medium voltage grids without using transformers. Conventional multilevel inverters are not capable of fault management and fault ride through
