Power Quality improvement by using DSTATCOM in power distribution system fed BLDC motor

Abstract

A Power quality problem is an occurrencemanifested as a nonstandard voltage, current or frequencythat results in a failure or a miss operation of end userequipment’s. Utility distribution networks, sensitiveindustrial loads and critical commercial operations sufferfrom various types of outages and service interruptionswhich can cost significant financial losses. With therestructuring of power systems and with shifting trendtowards distributed and dispersed generation, the issue ofpower quality. Utility distribution networks, sensitiveindustrial loads and critical commercial operations sufferfrom various types of outages and service interruptionswhich can cost significant financial losses.Distribution static compensator DSTATCOM) is ashunt compensation device that is generally used tosolve power quality problems in distribution systems. DSTATCOMforces load to operate always at rated power. Hence,customers need to pay for constant power continuously,whereas rated heating losses will take place in theequipments for entire operation. This concept proposes a hybrid control algorithm to maximize utilization and functionality of distribution staticcompensator (DSTATCOM). In this paper,implementing Power quality circuit with voltagesource converter in the BLDC Motor drive isdeveloped. The control of BLDC drive used is FieldOriented Control using pulse with Modulation. Thepower quality circuit proposed here improves thepower factor and reduces harmonic distortion.Simulation work is performed using MATLAB /SIMULINK environment.
