Abstract—This paper describes analysis results of a combined operation of the unified power quality conditioner with the dis- tributed generation. The proposed system consists of a series in- verter, a shunt inverter, and a distributed generator connected in the dc link through rectifier. The proposed system can compen-.
11 Jun 2014 This paper deals with the performance of unified power quality conditioner (UPQC) based on current source converter (CSC) topology. UPQC is used to mitigate the power quality problems like harmonics and sag. The shunt and series active filter performs the simultaneous elimination of current and
19 Dec 2017 Full-text (PDF) | This paper deals with unified power quality conditioner (UPQC), which aims at the integration of series-active and shunt-active power filters. The main purpose of a UPQC is to compensate for voltage imbalance, reactive power, negative-sequence current and harmonics. This paper di
CERTIFICATE. This is to certify that the thesis entitled, "Study of Unified Power Quality Conditioner for. Power Quality Improvement" submitted by Rajiv Kumar Sinku (Roll No. 213EE5352) in partial fulfilment of the requirements for the award of Master of Technology Degree in. Electrical Engineering with specialization in
Unified power quality conditioners (UPQCs) allow the mitigation of voltage and current disturbances that could affect sensitive electrical loads while compensating the load reactive power. Diverse control techniques have been proposed to evaluate the instantaneous output voltage of the series active power filter of the
Abstract—This paper deals with unified power quality condi- tioners (UPQC's), which aim at the integration of series-active and shunt-active filters. The main purpose of a UPQC is to com- pensate for voltage flicker/imbalance, reactive power, negative- sequence current, and harmonics. In other words, the UPQC has the
Abstract. A unified power quality conditioner (UPQC) is a device that is similar in construction to a unified power flow conditioner (UPFC) [1]. The UPQC, like a UPFC, employs two voltage source inverters (VSIs) that are connected to a common dc energy storage capacitor. One of these two VSIs is connected in series with
Abstract-- Power Quality is an issue that is becoming increasingly important to electricity consumers at all levels of usage. The nonlinear characteristics of power electronic devices give rise to two important limitations; they generate harmonics and draw lagging current from the utility. In recent years unified power quality
