Download or read book Design of Single-phase Active Power Filter for Harmonic Mitigation in Distribution Power Lines written by Mohamed S.A. Dahidah and published by . This book was released on 2002 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, the wide use of power electronic in various applications has affected the quality of the power. One of the most serious problems is that of the harmonic, which is generated from the nonlinear loads such as variable frequency AC motor drives, uninterruptible power supplies (UPSs), personal computers, laser printers, and many more [1-4], is has harmful effect on the electrical equipment. Several techniques have been carried out over the year to prevent the effects of the harmonic [3], [7]. The active power filter is the most efficient method, which has developed in different configurations to meet the different demands [9]. This thesis presents the design and development of a single-phase shunt active power filter that is suitable for commercial or educational buildings with computer loads [9]. The proposed filter is designed to migitate the third and fifth order harmonics for two main reasons. Firstly, because of using large number of relatively small single-phase loads that many produce excessive total amount of the third harmonic fifth and seventh harmonic [3]. Secondly because of the active power filter rating could be highly reduced when the suppression of one or two special harmonics is effected by the active filter [20]. Full-bridge single-phase inverter is designed as active power filter to cancel the harmonics generated from the nonlinear load. We preferred the voltage-fed PWM inverter to the current-fed PWM inverter because the voltage-fed PWM inverter is higher in efficiency and lower in initial costs than the second one [16], [20]. IGBT was chosen as power switches for the inverter due to its simplicity of controlling the gate as well as lower cost as compared to the thyristor [6]. Sinusoidal pulse width modulation (SPWM) was introduced as a technique to control the output of the inverter due its ability to control the frequency and the phase angle of the inverter output. The control of active filter is accomplished by monitoring the current to the nonlinear load and then generating gate signals for the inverter to create a current waveforms that will cancel the harmonic components in load current by performing a rolling FFT on the sampled load current waveforms and then reproducing a current waveform that has the same harmonic components with opposite phase angle. The design of the active power filter is verified by doing the simulation using the capabilities of PSPICE. The result shows that the THD is reduced from 41.1% to 5%, which is acceptable with referring to IEEE-519 limits. The inverter circuit has been successfully implemented in the laboratory as the active power filter and it is capable to generate variables frequencies (i.e generating the third and fifth harmonics). Finally, the experimental results are compared and they agree with the simulation study as given in chapter 4 of this thesis.

Book Synopsis Hybrid Active Power Filter by : Zainal Salam
Download or read book Hybrid Active Power Filter written by Zainal Salam and published by LAP Lambert Academic Publishing. This book was released on 2009-08 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent proliferation of non-linear loads such as adjustable-speed motor drives, power supplies and inverters have raised serious concerns on the quality and reliability of electrical distribution networks. These loads draw excessive harmonic currents which interact with a wide range of power system components, causing significant deterioration in the power quality. Although traditional passive filtering has been commonly used to mitigate these problems, recent advances in power electronic converters have sparked the interest in active power filter (APF) approach. This book describes the design, analysis and implementation of a hybrid APF connected to a photovoltaic system. The integration improves the harmonic filtering performance of a basic shunt APF while simultaneously supplying power from the photovoltaic array to the load. The compensation current reference for the APF is derived from the extension instantaneous reactive-power theorem. It simplifies the current reference estimation, leading to a more efficient implementation using digital signal processor.

Book Synopsis Digital Control in Power Electronics by : Simone Buso
Download or read book Digital Control in Power Electronics written by Simone Buso and published by Morgan & Claypool Publishers. This book was released on 2015-05-01 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the reader, whether an electrical engineering student in power electronics or a design engineer, a selection of power converter control problems and their basic digital solutions, based on the most widespread digital control techniques. The presentation is primarily focused on different applications of the same power converter topology, the half-bridge voltage source inverter, considered both in its single- and three-phase implementation. This is chosen as the test case because, besides being simple and well known, it allows the discussion of a significant spectrum of the most frequently encountered digital control applications in power electronics, from digital pulse width modulation (DPWM) and space vector modulation (SVM), to inverter output current and voltage control, ending with the relatively more complex VSI applications related to the so called smart-grid scenario. This book aims to serve two purposes: (1) to give a basic, introductory knowledge of the digital control techniques applied to power converters; and (2) to raise the interest for discrete time control theory, stimulating new developments in its application to switching power converters.
