This paper outlines a new approach for the compensation of power systems presented through the use of a unified power quality conditioner (UPQC) which compensates impulsive and oscillatory electromagnetic transients. The newly proposed control technique involves a dual analysis of the UPQC where the parallel compensator is modelled as a sinusoidal controlled voltage source, while the series compensator is modelled as a sinusoidal controlled current source, opposed to the traditional approach where the parallel and series compensators are modelled as current and voltage nonsinusoidal sources, respectively. Also a new compensation algorithm is proposed through the application of the theory of generalized reactive power; this is then compared with the theory of active and reactive instantaneous power, orpqtheory. The results are presented by means of simulations in MATLAB-Simulink®.

“…Vector algebra is suggested as very useful tool for the definition of power components in three‐phase a–b–c coordinate systems. Many publications appeared to express power component using concepts like tensor product, asymmetrical tensor, multivector, and so on . These definitions have given new direction to researcher for designing control circuit of APF system in three‐phase a–b–c coordinate systems.…”

SUMMARYFor high power application of active power filters, series hybrid active power filter (SHAPF) configuration is popular because of its multi-functionality and small capacity inverter requirement. The SHAPF filtering characteristics and efficiency of harmonic compensation depend on the control algorithm applied to calculate the reference voltage. This paper compares the filtering performance of SHAPF using three different control algorithms applied for reference voltage generation. The first control algorithm derives reference voltage proportional to the source current harmonics, where the source current harmonics are separated using the p-q theory. The second control algorithm derives reference voltage from load voltage harmonics separated using the dual p-q theory. The third control algorithm derives reference voltage using vector algebra-based voltage decomposition method in three-phase coordinate system. The mathematical formulation of selected three control algorithms along with their applications to SHAPF is presented. To check the filtering performance of SHAPF with selected control algorithms, an experimental prototype of SHAPF controlled by the ARM Cortex M4 microcontroller STM32F407VGT6 is developed. Experiments are performed to check the performance of SHAPF in compensating current harmonic generating load and voltage harmonic generating load. The results of compensation, the complexity involved in extracting reference, and control algorithm computation time are compared. The comparison shows that the operation of the voltage decomposition method is comparatively better due to fast extraction of the reference voltage.
