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...
متن کاملFuzzy Controlled DSTATCOM for Voltage Sag Compensation and DC-Link Voltage Improvement
In this paper we propose fuzzy control of DC-link capacitor voltage of three-phase four-wire DSTATCOM for power quality improvement in distribution network. It is designed to compensate reactive power and to eliminate harmonic currents. DSTATCOM regulates the voltage at the point of common coupling (PCC) by injecting reactive power to the PCC. During load changes there is considerable variation...
متن کاملIntelligent Control of DSTATCOM for Voltage Sag Improvement Using Firefly Algorithm Optimized Fuzzy Logic Controller
In this paper improvement in voltage sag by using firefly algorithm optimized fuzzy controller is described. DSTATCOM is the FACTS device used in voltage sag improvement. Firefly algorithm optimization is used to optimize the if-then rules of the fuzzy controller. In this system a DSTATCOM is placed in a three phase system to control the voltage sag. A fuzzy controller is designed to control th...
متن کاملSimulation and Modeling of 24-Pulse STATCOM in EMTDC/PSCAD Program in Order to Regulate Voltage and Dynamic Stability Improvement
This study starts from the proof of Low Frequency Oscillation (LFO) and then points out that there are many ways to study the LFO including its rejection measures. Also in this study one control system is planned in order to regulate voltage at common coupling point (PCC) in where STATCOM is installed. This research present a single-machine infinite-bus system with one static synchronous compen...
متن کاملAnalysis and Design of a DSTATCOM Based on Sliding Mode Control Strategy for Improvement of Voltage Sag in Distribution Systems
Abstract: Voltage sag is considered to be the most serious problem of power quality. It is caused by faults in the power system or by the starting of large induction motors. Voltage sag causes about 80% of the power quality problems in power systems. One of the main reasons for voltage sag is short circuit fault, which can be compensated for by a distribution static compensator (DSTATCOM) as an...
