Load compensation using DSTATCOM in three-phase, three-wire distribution system under various source voltage and delta connected load conditions

A review of distribution static compensator

“…A comparative study of isolated and nonisolated VSC-based 3P3W DSTATCOM topologies is carried out based on critical reviews of publications [43][44][45][46][47][48][49][50][51][52][53][54] and presented in Table 1. The numerical data included in the table are just indicative of the approximate values of the elements.…”

“…The second category comprises of DSTATCOM configuration, principle of operation and its potential applications. The third category is on the DSTATCOM topologies which is further sub-classified in to 3P3W [43][44][45][46][47][48][49][50][51][52][53][54] and 3P4W . The fourth category is on DSTATCOM control techniques which is sub-classified into IRP theory [99][100][101][102][103][104][105], SRF theory [106][107][108][109], SC theory [110,111], AUPF theory [112,113], PI controller [114][115][116], adaline based neural network [117][118][119], sliding mode controller [120][121][122], and miscellaneous control techniques [123][124][125][126][127].…”

Dağıtım Sistemleri için Çok Fonksiyonlu Statik Senkron Kompanzatör

“…Literatürde, son yıllarda D-STATKOM ile ilgili çalışmaların sayısı artmış olup, kontrolcüsü zaman veya frekans düzleminde referans sinyalleri üretilerek kompanzasyonu gerçekleştirmektedir. Örnek olarak ani gerilim ve/veya akım vektörlerinin zamana bağlı sinyalleri algılanır ve bu sinyaller DQ Dönüşümü [1][2][3][4], PQ Dönüşümü [5][6][7], geri yayılım [8], karma gözlemci tabanlı [9], vektör kuantalamalı öğrenme [10], uyarlamalı eş-zamanlı referans çıkarma [11][12], yapay sinir ağları tabanlı Anti-Hebbian algoritması [13], üçgen fonksiyon karakteri [14], ayarlanabilir adımlı en küçük kareler [15], Adaline yapay sinir ağları [16] …”

Prototype hardware realization of the DSTATCOM for reactive power compensation

“…If the grid voltage V s is greater than the DSTAT-COM voltage V c (V s > V c ), the DSTATCOM absorbs reactive power from the grid and the DSTATCOM is operating in the inductive mode. If the grid voltage V s and the DSTATCOM voltage V c are of the same magnitude (V s = V c ), there is no exchange of reactive power between the grid and the DSTATCOM and the DSTATCOM is operating in the floating state [1][2][3][4][5].…”

“…If the grid voltage V s is greater than the DSTAT-COM voltage V c (V s > V c ), the DSTATCOM absorbs reactive power from the grid and the DSTATCOM is operating in the inductive mode. If the grid voltage V s and the DSTATCOM voltage V c are of the same magnitude (V s = V c ), there is no exchange of reactive power between the grid and the DSTATCOM and the DSTATCOM is operating in the floating state [1][2][3][4][5].The DSTATCOM can be controlled by many control techniques such as the PI controlled sine pulse width modulation (SPWM), the PI controlled space vector pulse width modulation (SVPWM) and the hysteresis current controller (HCC) [6][7][8][9][10][11]. The SPWM and SVPWM methods are indirect methods for controlling the output current of the DSTATCOM.…”
