Research ArticleOpen accessIn the keywordsGrid Voltage Stability Enhancement Using Photovoltaic Based Static Synchronous CompensatorSubhransu Sekhar Dash, Arun Bhaskar Mayilvaganan, Venkatesh VenkataramananToday, we are mostly dependent on non renewable energy that have been and will continue to be a major cause of pollution and other environmental degradation. Because of these problems and our dwindling supply of petroleum, finding sustainable alternatives is becoming increasingly urgent. Perhaps, the greatest challenge is in devising a sustainable future, which relies on integration and control of … …Journal of Computer Science, Vol. 9, Issue 3 · 17 Apr 2013 · 6,861 accessesView PDFCite

AbuzalataProblem statement: This study concerns with designing of Pulse Width Modulation (PWM) techniques and analyzing of their waveforms to initiate a comparative numerical study. Approach: This study enables the people interesting in developing the motional control algorithms of adjustable DC drive schemes (e.g., DC-DC converters). Results: LabView software was used as a real-talk simulation environment to design and analyze of … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 12 Dec 2011 · 8,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultimode Controller Design for DSTATCOM integrated with Battery Energy Storage for Smart Grid ApplicationsSai Pranith, T.S. BhattiA Distribution Static Compensator (DSTATCOM) can provide reactive power support, power factor correction and voltage regulation to a distribution system feeder. In this paper, a multimode multifunctional control algorithm is proposed for the controller of the Voltage Source Converter (VSC) to provide DSTATCOM and load leveling functionalities for smart grid applications through a Battery Energy Storage System (BESS) connected to … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 26 Oct 2017 · 8,399 accessesView PDFCite
Review ArticleOpen accessIn the abstractArchitecture of an Ultra-Low-Power Fully Autonomous Universal Power Conditioner of Energy Harvester for Wireless Sensor Networks: A ReviewYeo Kim Heng, Md. Shabiul Islam, Susthitha Menon et al.A fully autonomous Universal Power Conditioner (UPC) that can accept energy from any micro-energy harvester (e.g., photovoltaic, thermoelectric, electromagnetic, piezoelectric etc.) is proposed. Generally, UPC removes the need of multiple optimized source specific converters. But, the proposed UPC architecture will be Ultra-Low-Power (ULP) with maximized efficiency to support the low energy levels generated by harvesting sources. This UPC uses a … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 7,782 accessesView PDFCite
Research ArticleOpen accessIn the abstractEMBEDDED CONTROLLED MULTI LEVEL VOLTAGE SOURCE INVERTER BASED DISTRIBUTION STATICS SYNCHRONOUS COMPENSATORP. Venkata Kishore, S. Rama ReddyThis study deals with the D-STATCOM used as a shunt connected compensator for the voltage support. The D-STATCOM has a faster response as compared with the conventional compensators such as the synchronous condenser and the SVC. The D-STATCOM can provide voltage support and improve power quality. The D-STATCOM supplies reactive power to the load to improve the voltage stability of … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 5 May 2014 · 6,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractDESIGN OF FUZZY LOGIC CONTROLLER FOR ONLINE SPEED REGULATION OF DC MOTOR USING PWM TECHNIQUE BASED ON LABORATORY VIRTUAL INSTRUMENT ENGINEERING WORKBENCHPrema Kannan, Senthil Kumar Natarajan, Subhransu Sekar DashThis study details online speed regulation of DC motor using PWM technique based on LabVIEW. A fuzzy logic controller is designed to change the pulse width of switching signal applied to the converter and thereby the voltage fed to the armature of the separately excited DC motor to regulate the speed. The proposed system is connected to the server computer … …Journal of Computer Science, Vol. 9, Issue 8 · 4 Jul 2013 · 6,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation and Implementation of Quasi Resonant DC-DC ConverterP. Parvathy, N. DevarajanProblem statement: A half-bridge LLC resonant converter with a voltage doubler rectifier has a simple structure and its Zero-Voltage-Switching (ZVS) capability is excellent from zero to full load condition. But conduction loss is more due to high circulating energy thus reducing the system efficiency. Moreover a variable frequency control method makes the control circuits more complicated than those using the … …Journal of Computer Science, Vol. 8, Issue 10 · 29 Aug 2012 · 7,142 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectric Power System Under-Voltage Load Shedding Protection Can Become a TrapLuiz Augusto Pereira Fernandes, Alexandre Rocco, Heraldo Silveira Barbuy, Geraldo Caixeta GuimarãesProblem statement: Under-Voltage Load Shedding (UVLS) protection of Electric Power Systems (EPS) is frequently used against Voltage Collapse (VC), however when there is automatic bus voltage regulation with excessive capacitive compensation, the UVLS scheme may not trip. In this case, load shedding must be based in a Voltage Collapse Proximity Indicator (VCPI). Many UVLS procedures may not be appropriate today. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,203 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Quality Improvement Using a Sliding Mode Control of a Series Active FilterTheerayuth ChatchanayuenyongA sliding mode controller (SMC) for a three-phase series active filter was proposed to compensate voltage unbalances, suppress voltage sags and swells and hence improve the power quality of a three-phase ac system. The voltage unbalance compensation and regulation is only based on the positive sequence component decomposition of the supply voltage that is then adjusted to a rated value … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,584 accessesView PDFCite
