“…Passive filter connected between VSI and injection converter, eliminates harmonic components of high order in outlet voltage of the inverter (Wang et al, 2014;Jena et al, 2015;Elbeji et al, 2014). The VSI power storage device provides the required effective compensation power (Jou et al, 2004). DVR compensation capacity depends on the width of the sags and the size of the energy storage.…”

Various power quality issues happening in power system and its mitigation techniques are briefly explained in this paper. There is large demand of power for which the power system needs to be upgraded for the stability and reliability of the power system network, it is necessary for the betterment of power quality. Electric power quality (PQ) is normally used for accessing better power quality at the point of generation, transmission, distribution. Voltage, current and frequency are the main criteria for the estimation of the quality of power. Problems on quality of power can be considered as the difference between the supply power quality and the required power quality for the smooth operation of the system. Some advanced power electronic based Custom Power Devices (CPDs) such as dynamic voltage restorer (DVR) distributed static synchronous compensator (D-STATCOM) and UPQC have been improved as the traditional devices can’t minimize the power quality problems. The aim of this paper is to present the overview of the supply system and detect the problems related to power quality happening in the power system and to study the methods that are present for eliminating this type of problems.

“…The SHAPF filtering characteristics and efficiency of harmonic compensation depend on the control algorithm (CA) applied to calculate the reference voltage. A number of control approaches have been proposed to achieve the desired harmonic compensation using SHAPF . The control techniques reported in the literature to derive the reference voltage for SHAPF may be broadly categorized into three approaches.…”

“…Several publications appeared in the literature that suggests different definitions of instantaneous power theories for deriving reference quantities. Instantaneous p‐q theory, dual p‐q theory, synchronous reference frame theory, vectorial theory, generalized a–b–c reference frame theory, and so on are few widely used definitions used by researchers for separating reference for hybrid active filters . Vector algebra is suggested as very useful tool for the definition of power components 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.
