Enhancement of Power Quality and Voltage Sag Mitigation Using a Novel Nine Switch Power Conditioner
نویسندگان
چکیده
This paper proposes a novel nine switch converter based integrated power conditioner in place of conventional twelve switch converter based power conditioner for improving power quality. Space vector modulation scheme is proposed for producing gating signals for nine switch converter. In the proposed integrated power conditioner the nine-switch converter replaces shunt and series converters found in conventional back to back power conditioner. Underlying operating principles are discussed comprehensively to demonstrate, how such “series–shunt” replacement can bring forth the full advantages of the nine-switch converter. The shunt and series compensation techniques are discussed and the performance of the proposed nine switch power conditioner is validated through simulations using MATLAB/SIMULINK.

Power quality is one of major concerns in the present area. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply that results in a failure of end use equipment’s. One of the major problems dealt here is the voltage sag. To solve this problem, custom power devices are used. One of those devices is ...
متن کاملPower Quality Enhancement in Grid Connected Wind Power System Based on Dfig Using Fuzzy Controlled Upqc
The renewable energy resources rule the world of power generation. Now-a-days wind farms are encouraged for up gradation of energy production, as the wind power is dirt free, readily available renewable alternative. The integration of wind farms with power grid leads to Power Quality (PQ) issues such as voltage sag, swell, flicker, harmonics etc. Most of the industrial and commercial loads are ...
متن کاملA New Control for Series Compensation of UPQC to Improve Voltage Sag/Swell
Voltage sag/swell is one of the most frequently power quality problems which affects the power systems with sensitive loads. The unified power quality conditioner (UPQC) is capable of mitigating the effect of voltage sag/swell at the load or point of common coupling (PCC). In this paper, a new control of UPQC is proposed based on combining the sag detection and voltage injection established on ...

This paper presents a new control method for a three-phase four-wire Unified Power Quality Conditioner (UPQC) to deal with the problems of power quality under distortional and unbalanced load conditions. The proposed control approach is the combination of instantaneous power theory and Synchronous Reference Frame (SRF) theory which is optimized by using a self-tuning filter (STF) and without us...
