PSCAD Simulation Model of D-Statcom for Voltage Sag Improvement

This paper deals with the modeling and simulation of Distribution Static Compensator (D-STATCOM) for voltage sag mitigation. The D-STATCOM simulation model consists of 12-pulse inverter, which is connected in shunt with the system. A generalized sinusoidal pulse width modulation (SPWM) technique was developed in the proposed controller for fast control action of the D-STATCOM. Simulations of th...

Design of DC Voltage Control for D-STATCOM

This paper presents the DC voltage control design of D-STATCOM when the D-STATCOM is used for load voltage regulation. Although, the DC voltage can be controlled by active current of the D-STATCOM, reactive current still affects the DC voltage. To eliminate this effect, the control strategy with elimination effect of the reactive current is proposed and the results of the control with and witho...

Low Power Low Voltage Current Mode Pipelined A/D Converters

This paper presents two prototypes of low power low voltage current mode 9 bit pipelined a/d converters. The first and the second converters are configured of 1.5 bit and 2.5 bit stages, respectively. The a/d converter structures are composed of current mode building blocks and final comparator block which converts the analog current signal into digital voltage signal. All building blocks have ...

Application of Distribution Static Compensator (D-STATCOM) to Voltage Sag Mitigation

This paper presents a study of a D-STATCOM (Distribution Static Compensator) used for mitigating voltage sag. The basic idea of the voltage sag mitigation, using a D-STATCOM is to dynamically inject a current of desired amplitude, frequency and phase into the grid line. The proposed method extracts the active and reactive parts of the positiveand negative-sequence component for generating refer...
