Reduced Sensor Based Control of PV-DSTATCOM with Switch Current Limiting Scheme

The work delineated in this paper deals with the reduced sensor-based operation of PV-DSTATCOM (Photovoltaic distribution static compensator) focusing on voltage source inverter (VSI) switch current limiting control. In study, soft computing technique control based variable leaky least mean square (VLLMS) algorithm is modified to incorporate both sensor and schemes. DSTATCOM predominantly introduced improve related power quality issues by providing non-real (i.e., reactive harmonic component) load demand. However, during uncertain increase requirement at end due sudden change demand or any other transient conditions, injected may a level which beyond handling capacity switches. As consequence, switches become permanently damaged and, subsequently, performance will deteriorate. Hence, through VSI can be limited controlling amount flow from DSTATCOM. During high condition, transits improvement mode protection mode. result, unity factor P.C.C (common point coupling) compromised for that period few cycles condition. Moreover, efficient demands proper information about system, are determined sensors. faults these sensors deteriorate controller degrade system efficacy. Therefore, mitigate issue, numbers measurement units i.e., only two phases as well grid, line voltages using instead three each phase. reduction accomplished without compromising efficiency. Further, studied MATLAB/Simulink under different condition steady- state, varying solar irradiance, increasing above rated capacity.
