“…The voltage applied to the primary of the DVR transformer is combination of voltages at different frequencies [24], [48]. The sum of the maximum flux densities (at the different frequency components) should be less than the permissible maximum value of the ac flux density Bac_max_eqa and is given by 𝐵 𝑎𝑐_max _𝑒𝑞𝑢 = 𝐵 1𝑚𝑎𝑥 cos(𝜔𝑡 + 𝛿 1 ) + 𝐵 2𝑚𝑎𝑥 cos(2𝜔𝑡 + 𝛿 2 ) … 𝐵 𝑛𝑚𝑎𝑥 cos(𝑛𝜔𝑡 + 𝛿 𝑛 ) (8) where B1max, B2max … Bnmax are the maximum flux densities of voltages at multiple frequency components x=1,2…n respectively.…”

Nowadays, power quality under the excessive implementation of power electronics devices is quite challenging issue. The compensation of non-sinusoidal; reactive and harmonic; components is the main role for power quality devices which highly depend on the robustness of the control system. Some common control systems are implemented using DQ theory. This paper proposes a new version of DQ control technique to control dynamic voltage restorer under severe transient voltage conditions. The power system network with the new DQ control technique is studied and analyzed under different scenarios to compensate for severe balanced and unbalanced voltage sags and swells. This new scheme is based on extraction of positive sequence components to implement the control algorithm. A mathematical model of the DVR, hysteresis voltage control, converter controller model, new DQ scheme with complete system equations are carried out and verified using Simulink / MATLAB. The proposed system is validated experimentally using DSpace 1104 based laboratory system. The obtained results of the proposed compensation algorithm are compared with the results obtained from the traditional DQ method. Simulation and experimental results are correlated and show effectiveness of the proposed DQ control scheme.

“…Specifically, with sensitive loads, the detecting system should be fast enough to identify the voltage disturbance accurately for the assessment of DVR performance [20] [45]. As shown in Figure 2, various methods for voltage disturbance detection have been proposed, including RMS, Peak Value, DFT, Fourier Transform (FT), Wavelet Transform (WT), Windowed Fast FT (WFFT), ABC to DQ axis transformation, KF, Phase-Locked Loop (PLL), and SRF [28] [46]. The benefits and drawbacks of the most serious voltage disturbance detection techniques are provided in Table I.…”

“…The low inverter losses and reduced harmonic content welcomes the open end winding transformer into the DVR topology [64]. A multilevel inverter based DVR coupled with cascaded open-end winding (OEW) transformer is reported in [65]. However, [2] rules out the need for multilevel structures in FACTS.…”

Power quality (PQ) is gaining a great deal of importance as more sensitive loads are introduced into the utility grid. The degradation of product quality, damage of equipment and temporary shutdowns are the general issues associated with PQ problems in industries. Any mal-operation or damage of the industrial sensitive loads results in monetary losses disproportionately higher than the severity of the PQ issues. The evolution of power electronics technology replaced the traditional power quality mitigation methods with the introduction of Custom Power System devices (CUPS). The major power electronic controller based CUPS are DSTATCOM, DVR and UPQC. DVR is a pertinent solution for the economic losses caused by the PQ issues in the industries. Among the CUPS, DVR is the most cost-effective one. In the published literature, only a few papers correspond to the review of DVR technology. In this paper, a systematic review of published literature is conducted and a description is given on the design, standards and challenges in the DVR technology. A detailed survey is conducted on the published
