Lithological Investigation at Tombia and Opolo Using Vertical Electrical Soundings and Pseudo Tomogram Francis Omonefe, Edeye Ejaita, Eteh Desmond Rowland Niger Delta University, Wilberforce Island, Amassoma, Nigeria Abstract:-Vertical electrical soundings (VES) was carried out in Opolo and Tombia all in Yenagoa local government area, Bayelsa state, Nigeria to understand the resistivity distribution of its subsurface which serves as a tool in investigating subsurface lithology. All […]
Exploring Control Design of a PV-Wind Hybrid OnGrid System without ESD Abstract—there is general practice to support and compensate intermittent behavior of Solar photovoltaic (PV) system with energy storage devices (ESD) and the one generally adopted is battery energy storage (BES) simply because of lower cost as compared to fuel cells or a bank of super capacitors. However, cost of battery maintenance, inherent shorter life, even […]
A Study on Voltage Regulation using Fuzzy Analysis Abstract — A fuzzy logic controller (FLC) [1] with fast reference watts generation to correct and regulate unbalance watts in three-phase system is proposed in [2]. We designed an efficient algorithm to regulate the unbalance watts in three-phase system under different conditions of the utility supply. In our simulation test, the Fuzzy Logic control shows consistent excellence […]
3D Modeling of Double Sided Linear Synchronous Motor for EMALS Abstract—Electromagnetic aircraft Launch System is integrated system used for launching naval aircraft. To accelerate the aircraft to launch speed; EMALS uses linear motor. At this state, Double sided linear synchronous motor (DSLSM) looks to be a far better as well as an improved alternative owing to higher potency and better power issue, which might plainly […]
“A Study of Response of Switched Reluctance Motor SRM In Sensor-Based and Sensor-Less Control Mode” Abstract: – This paper aims at implementing a Switched Reluctance Motor drive in sensor-based mode using dsPIC30F6010 motor control demo-board. For this purpose, initially the sensor-based and sensor-less control technique for the SRM drive have been studied. The simulation model in sensor-based operation has been developed in SIMULINK/MATLAB environment and […]
Abstract- This paper highlights the problems associated with single pulse width modulation, the most important being high harmonic content in output voltage. A comparative study with Sinusoidal Pulse Width Modulation Technique is done highlighting the reduction in Total Harmonic Distortion of the output voltage waveform. Keywords- Sinusoidal Pulse Width Modulation(SPWM), Total Harmonic Distortion(THD), Fast Fourier Transform(FFT) Analysis, Carrier Wave Frequency, Modulating Index(MI), Low Pass Filter(LPF). […]
A Single Area Load Frequency Control (LFC): Comparative Study Based on Integral and Fuzzy Logic Controller Abstract: The comparative analysis of integral and fuzzy logic controller for load frequency control has been described in this paper. Local feedback signal from the output to the input has been injected to the controller. A single area power system is simulated to validate the effectiveness of the controller. […]
Abstract-The proposed model of automated cooking machine is the basic model which we further used in cooking or food industry. Because in food or cooking industry one could not able to provide manual faults. Recently everything is based on technology where we have to serve technology by automated systems .by this automation technology we can reduce the man power and with reducing the errors. And […]
