“…For detection and analysis of voltage events (voltage sag and swell) in distribution system Kalman filter have been used. The Kalman filtering method gives the information on both magnitude and phase angle of the supply voltage during the voltage sag and swell events and the point-on-wave where the voltage events begin unlike the RMS method [18], [20], [81], [98], [121], [145], [212].…”

“…The most popular form of pulse width modulation (PWM) synthesis is the sinusoidal pulse width modulation (S-PWM) [20], [47], [77], [80][81][82], [107], [111], [112], [117], [125], [126], [130], [203], [205], [207]. In an S-PWM scheme the modulating signal is sinusoidal and carrier signal is a triangular wave.…”

“…Single-phase two-wire (1p2w) systems are used in all three modes as shunt (D-STATCOM) [71][72][73][74], series DVR [75][76][77][78][79][80][81][82][83] and a union of both as UPQC [84][85][86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101]. 215 Figure 9 (a-c) shows the most popular DSTATCOM, DVR and UPQC configurations consist of two H-bridge inverters [72][73][74], [83], [84], [86][87][88][89][90][91][92][93][94][95][96][97], [99], …”

Electrical power quality (EPQ) in distribution systems is a critical issue for commercial, industrial and residential applications. The new concept of advanced power electronic based Custom Power Devices (CPDs) mainly distributed static synchronous compensator (D-STATCOM), dynamic voltage restorer (DVR) and unified power quality conditioner (UPQC) have been developed due to lacking the performance of traditional compensating devices to minimize power quality disturbances. This paper presents a comprehensive review on D-STATCOM, DVR and UPQC to solve the electrical power quality problems of the distribution networks. This is intended to present a broad overview of the various possible DSTATCOM, DVR and UPQC configurations for single-phase (two wire) and three-phase (three-wire and four-wire) networks and control strategies for the compensation of various power quality disturbances. Apart from this, comprehensive explanation, comparison, and discussion on D-STATCOM, DVR, and UPQC are presented. This paper is aimed to explore a broad prospective on the status of D-STATCOMs, DVRs, and UPQCs to researchers, engineers and the community dealing with the power quality enhancement. A classified list of some latest research publications on the topic is also appended for a quick reference.

“…The neural network architecture is adopted for pattern recognition and is used along with fuzzy controller for power disturbance detection [101]. A robust detection method with least estimation error when compared to KF and FFT algorithms gives excellent results during frequency varying conditions and sags with and without phase jumps [102]. The twopoint approach based period phase method of voltage sag/swell magnitude and phase jump detection introduced in [96] is easy to realize and is popularly used among three phase and single phase power lines.…”

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
