Abstract:

This paper concentrated on the power quality improvement in distributed networks with utilizing FACTS technology. In the suggested paper implemented a new algorithm with the reference voltage are generated by presenting the distributed static compensator (DSTATCOM) under voltage control operation. The developing model which is maintained the unity power factor is generated under abnormal conditions, it is not possible by utilizing conventional topologies. Also maintained active and reactive powers effectively and the harmonic analysis is provided to improve the performance by identifying the THD distortion levels. Whenever the presence of voltage sags in the distribution regions in that situation DSTATCOM can identified the problems and those problems are compensated with the high rating capabilities from the STATCOM. Whenever the abnormal conditions occurred in the systems such conditions the presence of ripple contents very high in load side. But by the STATCOM we can reduce the harmonic levels effectively b controlling the voltage references in the voltage source converter effectively which can improves the behaviour of distributed side. The state space model is developed by DSTATCOM with hysteresis controller. The hysteresis controller is activated with the help of dead beat controller under the abnormal load conditions. The Simulink models are tested and verified within the MATLAB/SIMULINK. Finally as a result power quality issues were compensated, improves power factor levels, active and reactive power also compensated, THD levels also minimized load requirements are achieved properly by the utilization of DTSTATCOM.
