Voltage source converter based DSTATCOM has been accepted as the most preferred solution for reactive power management in distribution power networks which plays a vital role in improving power quality, correcting power factor and maintaining constant distribution voltages. However, the quality of DSTATCOM output voltage and current itself, such as injected harmonics and Total Harmonic Distortion...
This paper describes an optimal dispatch for the under load tap changer (ULTC) of a substation transformer, substation capacitors, and feeder capacitors for volt/VAr control. The objective function of the problem is to minimize the system energy loss for a given daily load pattern. The problem is subjected to power flow equations, bus voltage limits, voltage distortion constraint and the maximum number...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
