Simulation and Analysis of Controllers of DSTATCOM for Power Quality Improvement
- Abstract
Power quality is an issue that is becoming increasingly important to electricity consumers at all levels of usage. Sensitive power electronic equipment and non-linear loads are widely used in industrial, commercial and domestic applications leading to distortion in voltage and current waveforms. The widespread use of electronic equipment, such as information technology equipment, power electronics based drives such as adjustable speed drives (ASD), programmable logic controllers (PLC), energy-efficient lighting, led to a complete change of electric loads nature. These loads are simultaneously the major causes and major victims of Power Quality (PQ) problems. Voltage Sag/ Swell, Interruptions, Flickers, Harmonic distortion and Poor power factor are the main problems those are associated with power quality. For mitigating the PQ problems various measures have been developed, in this paper a comparative study has been done for controllers of the SATCOM with linear as well as non- linear loads. SRF (Synchronous Reference Frame Theory), IRPT (Instantaneous Reactive Power Theory) and PI controller based Theory have been used for generating the reference source currents. This paper presents power quality improvement in the form of Power Factor Correction, Harmonic reduction and reactive power compensation using DSTATCOM and simultaneously Simulink models which are based on the Voltage Source Converter (VSC) principle have been developed. The DSTATCOM injects a current into the system to mitigate the problems associated with power quality specially in the case of load unbalancing. Results are shown in the form of waveforms using MATLAB. The simulation is performed in MATLAB in SIMULINK environment and PSB toolboxes have been used.
