Comprehensive Study of DSTATCOM Configurations

A review of distribution static compensator

“…Three-leg VSC and two-leg VSC-based isolated topologies of 3P3W DSTATCOM using star/delta transformer are shown in Fig. 6(b) and (c) respectively and have been reported in [44]. The transformer topology such as T-connected, zig-zag, and star/hexagon may also be used.…”

“…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].…”

A novel DSTATCOM with 5-level CHB architecture and selective harmonic mitigation algorithm

“…Therefore, a proper selection of DSTATCOM topology, control method and modulation technique are crucial for cost, efficiency and PQ optimization. In [3] different DSTATCOM topologies, state of the art, their performance, design considerations, future developments, and potential applications are investigated for power quality improvement. Paper [4] describes the design, implementation, and performance of a mediumsize distribution-type static synchronous compensator with the simplest two-level three-leg voltage source converter topology.…”

Nonlinear modeling and control of a photovoltaic fed improved hybrid DSTATCOM for power quality improvement

“…So to overcome these aforementioned problems the power quality enhancement devices like distribution static compensators (DSTATCOMs) came into picture which can provide the compensation for reactive power, changing harmonic orders and balancing of source currents when the loads are balance and as well as unbalanced [7]. Different topologies are proposed for DSTATCOM in literature [6][7][8][9][10][11] and for photovoltaic fed DSTATCOM (PV-DSTATCOM) in literature [3][4][5][12][13][14][15][16][17]. In traditional topologies, an L-type interfacing filter is used for shaping of the injected current by the inverter [8][9][10][11][12][13].…”
