Voltage flicker, a phenomenon of annoying light intensity fluctuation is caused by electric arc furnace (EAF). Voltage flicker is a major power quality concern for both power companies and customers. This paper presents a model of EAF and control algorithms for distribution static synchronous compensator (DSTATCOM) for voltage flicker mitigation. The EAF was modeled as a current source controlled...
The use of STATCOM is a practical method for improving quality of power in distribution systems. In this paper direct power control of three-phase pulse width modulated converter based STATCOM without line voltage sensors is presented. This system is based on virtual flux estimation. Theoretical principles of this method are presented along with simulation results. Advantages of VFDPC-SVM over other...
This paper presents simulation studies of an electric arc furnace (EAF) model in the MATLAB/SIMULINK environment. EAF was modeled as a current source controlled by a non-linear resistance. Voltage flicker, a phenomenon of annoying light intensity fluctuation, caused by EAF, has been a major power quality concern for both power companies and customers. A model was developed for the electric arc furnace...
This paper presents the simulation studies on a cascaded H-bridge converter based distribution static synchronous compensator (DSTATCOM) for improving the power quality of a distribution system. Voltage source converter based DSTATCOM has been established as the most preferred solution for management of reactive power in distribution utilities and for improving voltage regulation, power factor and...
The paper presents a novel phasor diagram of interior permanent magnet synchronous (IPMS) motor for steady state analysis. Starting from first principle, the phase decoupled spiral vector model of the IPMS motor has been obtained. A phase decoupled voltage equation in phasor can be obtained from the spiral vector IPMS motor at steady state. In the phasor diagram, the effect of reluctance variation...
Voltage source converter based DSTATCOM has been established as the most preferred solution for management of reactive power in distribution utilities and for improving voltage regulation, power factor and power quality in industries. For high power applications, cascaded H-bridge converter is the most ideal choice compared to neutral point clamped inverter and two-level inverter with series connected...
In a power distribution network of a power utility or industry, the reactive power management plays a major role in reducing distribution loss and maintaining constant distribution voltage. Voltage source PWM inverter based reactive power generator has fast response to reactive power demand and hence can be used for power factor improvement and voltage support. With the availability of new generation...
Reactive power management in a power distribution network of a power utility and industry plays a major role in reducing distribution loss, in maintaining constant distribution voltage and in improving power factor. The paper presents the simulation studies on a cascaded H-bridge converter based DSTATCOM for power factor improvement in power distribution set-up using load side compensation. In this...
