“…Some common approaches to generating the orthogonal signal for SRF include all-pass filter (APF), Hilbert transform, inverse Park transformation (IPT), differentiator, second-order generalised integrator (SOGI) and transfer delay method [11][12][13]. The SOGIbased PLLs drew significant attention for single-phase PLLs in literature, which employs a sinusoidal integrator to generate required QSG.…”

Phase-locked loop (PLL) is commonly utilised for AC power systems to detect phase and frequency. With the increasing use of small-scale distributed power generation, the technique becomes widely available for grid interconnection of renewable power source into single-phase AC distribution network. Through comprehensive analysis and design, this study proposed a new approach that includes dual independent control loops to enhance the transfer delay-based PLL capability in terms of speed and accuracy. The effectiveness and advantages of the proposed PLL structure are demonstrated by numerical simulation and verified by experimental test.

“…All-pass active RC-filters (ARCF), which provide amplitudefrequency responses (AFR) of low-pass filter (LPF), high-pass filter (HPF), band-pass filter (BPF), rejection filter (RF) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] at different outputs, are attractive for production in a form of special structural crystals [17,18] in conditions of small volume specific type of electronic equipment. At the same time, the application of promising electronic component base in ARCF, for example, differential difference amplifiers (DDAs) [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33], which provides new properties of frequency selection devices of this class, is of considerable interest.…”

We have suggested an architecture of the second-order all-pass active RC-filter (ARCF), based on three differential difference amplifiers (DDA's), which provides full set of amplitude-frequency responses (AFR's) (low pass filter (LPF), high pass filter (HPF), band pass filter (BPF), rejection filter (RF)). We have given the basic equations, which allow ARCF's. The results of computer simulation of the LPF, HPF, BPF and RF's are discussed. In case of small volume production it is possible to produce the given ARCF in a form of specialized structural arrays, in which LPF, HPF, BPF and RF characteristics are realized by using one of the seven inputs, to which the processed signal is supplied, and four outputs, from which the said signal is outputted. The ARCF is noted, because its transfer ratio and pole frequency are not changed, when the pole Q-factor is adjusted.

“…As per the customer view, the power problems are happen that will lead to the deviation in the voltage, current and frequency. In order to solve these power quality problems, flexible ac-transmission system (FACTS) is introduced and reported in [2][3][4][5]. The IEEE is defined by FACTS as power electronics based system and further static equipment that offer control of single or multi transmission system specifications to increase the controllability as well as power transfer ability.…”

In current days, the power quality issues in the interconnected power system are mainly happens due to the demand of electricity and utilization of large non-linear loads as well as inductive/capacitive loads. The power quality cries are voltage sag and swell in multi-bus power system (MBPS). In this article studies on a two bus, three bus and five bus power systems using DPFC. In order to eliminate the voltage sag and swell in the MBPS, a distributed power flow controller (DPFC) is designed. The structure of the DPFC consists of three-phase shunt converter and three single series phase converters. Both these converters are arranged in back-back voltage source inverters (VSIs). These converters are controlled with help of the pulse width modulation (PWM) scheme. The feedback controllers and reference signals are derived the PWM for DPFC to magnify the power quality problems in MBPS. The performance of the model is investigated at different loads by making of MATLAB/Simulink model. The simulation results are presented.
