The present work seeks to develop a magnetic levitation (MAGLEV) system suitable for a low-speed wind tunnel, to support light-weight models through building-block design, development and experimentation. Design of an appropriate electrical circuit, design of components, results obtained by simulation (on ORCAD-PSPICE) and experimental results obtained through bench-tests are presented. A set of button-type permanent magnet (total weight = 4 gm.) was considered as the object to be levitated and a coil-wound electromagnet used to create a magnetic force which opposed the weight of the object. Distance between the object and the electromagnet was measured using locally available Hall effect sensors and the output amplified using a locally available differential amplifier. Pulse Width Modulation was used to control the current required to generate the required electromagnetic force. The results show that even though the electromagnet was capable of levitating the object, maintaining perfect alignment of the CG of the object with respect to the centre of the electromagnetic force is an important issue. It is therefore suggested that a bar-magnet for the object and a horseshoe magnet for generating the required electromagnetic force would provide a solution. Further, since the model of a prototype can experience aerodynamic forces and moments along three axes, a satisfactory MAGLEV system requires use of multiple horseshoe magnets which can provide vectored electromagnetic forces to keep the object in force as well as moment equilibrium.

The following paper proposes a Space-Vector based active filter for 3-phase systems, in order to improve the source end power quality. A shunt converter topology has been considered, which is vector controlled in order to ensure a fundamental sinusoidal current drawn from the mains supply. The control scheme senses the supply side voltage and the load current to generate the three phase reference signals. Control action is achieved in the fundamental rotating (d-q) reference frame. The converter connected in parallel to inject a compensating current at the PCC so that the harmonics present in the line are cancelled out and the sinusoidal nature of current is restored. A three phase system supplying a rectifier load is considered here since it closely emulates the HV generators used in Fixed Room Radiology applications. The system has been simulated using MATLAB and the results are presented.

Asset Management Systems (AMS) are pivotal to build reliable and safe smart grids. An important function of AMS is the monitoring and diagnosis of the power transformers. Various tests are performed on power transformers to detect incipient faults. Among the available methods, Dissolved Gas Analysis (DGA) has been widely used and shown promise. However, interpreting the results of the DGA is challenging due to the availability of wide variety of methods such as Rogers ratio, Doernenburg ratio, key gas procedure of IEEE, Basic gas ratio and Duval triangle methods of IEC. The accuracy of the interpretation methods influences AMS performance leading to reliability issues in the grid. This investigation compares the accuracy of Duval method and basic gas ratio method to detect transformer faults from real-time fault data obtained from power transformers. Our results on data obtained from Electrical Research and Development Association for seven transformer incipient faults shows that the Duval method is accurate than the basic gas ratio method for identifying incipient transformer fault based on DGA results. Further, the basic gas ratio was not able to detect two of the seven faults. These results illustrate the need to integrate Duval method to detect power transformer faults within AMS.

A number of power transformer failures occur due to the addition of DBDS compound in transformer oil. When DBDS reacts with Cu, it results in the breakdown of DBDS and thus pawing way to the formation of CU2S. The CU2S on the surface of the copper conductor migrates from one layer to another layer of insulation papers (Kraft papers) and this results in lowering of dielectric strength and thus electrical faults occur. The metal passivators such as Irgamet 39™, Benzotriazole (BTA-Aldrich) and 6Bis-(1-methyl-1-phenylethyl) Phenol (BMPEP-Aldrich) can be used to suppress the formation of copper sulfide. This addition of metal passivators to oil does not reduce or eliminate DBDS [1-6]. In this paper the effect of DBDS on DC Resistance of paper oil insulation system has been studied Experimental study has been carried out to describe the role of DBDS in fall of DC Resistance of paper-oil insulation of transformers. Different quantities of DBDS were added with pure transformer oil and the effect it will have on dc resistance under different applied voltages for different time intervals have been compared and contrasted.

Scarcity of power has been one of the nightmare issues for mankind in the modern age. Renewable Energy Sources (RES) working parallel with conventional power plants are playing a lead role in narrowing the difference between supply and demand. Among all the available renewable energy sources wind-solar hybrid systems are the most popular one. Due to their natural advantage of being complimentary to each other, they are assuring reliability to the utility. Power quality issues arising due to the usage of non-linear loads at the point of common coupling are addressed with the help of power electronic device interfacing RES to the grid. The work presented in this paper consists of Modeling and Simulation of wind-solar hybrid energy system and interfacing it to the grid through the interfacing inverter. A suitable control strategy which will add shunt active filter functionality to the RES interfacing device to the grid is also undertaken.

Humidification plant in a textile industry is one of the major power consumers due to its continuous operation for maintaining required Relative Humidity (RH) and temperature of spinning plant to increase the quality of yarn. The traditional method of operation of induction motors in humidification plant was effective, but not energy efficient. To overcome this problem, the emerging trend is the widespread adoption of variable frequency drives (VFD) which can offer potential energy savings in a system by allowing continuous process of speed control. In this paper, modeling, simulation and performance analysis of `Open loop and closed loop speed control of induction motor using Variable frequency drive' in MATLAB/Simulink and the Performance Verification of humidification plant in a textile industry where VFDs are installed very recently are presented.

This paper presents the performance study of a speed sensor-less control of grid connected DFIG based variable speed Wind Energy Conversion System (WECS). A new phase locked loop (PLL) based slip speed estimator using rotor current is proposed for speed sensor-less stator field oriented vector control operation of rotor side converter (RSC) to ensure decoupled control of stator active and reactive power while maximizing the power generation at unity power factor under varying wind speed. The estimated slip speed is used for back emf compensation of rotor current controllers. Simulation has been carried out in MATLAB/ Simulink environment and results show satisfactory operation of the proposed speed sensor-less DFIG based variable speed WECS.

This paper presents the load frequency control of hybrid renewable energy system (HRES) with varying load demand and solar radiation using particle swarm optimization (PSO) based tuned controller and classical state feedback technique like linear quadratic regulator (LQR). To analyze the performance of PSO and LQR on load frequency control, HRES with three component configuration is modeled in MATLAB/SIMULINKR environment. The HRES studied consist a photovoltaic module, a diesel engine generator (DEG) and a battery energy storage system (BESS). Solar radiation and load demand is not constant throughout the day and night. Hence, HRES system requires controllers and other components like DEG and BESS to mitigate the frequency deviation. The optimal frequency deviation response for HRES is obtained using PSO optimized controller and with LQR is compared and presented.

This paper presents mathematical model and robust control design for Inverted Flexible Beam (1KB) on cart system. Firstly, the system of IFB on cart is modeled using energy approach. Flexibility of beam is accounted by assuming spring- connected imaginary structure. Proposed model is simulated and validated with experimental results. Secondly, a robust Sliding Mode Control (SMC) is developed to stabilize the beam vertically on the cart, despite the action of uncertainties and disturbances on the system. A stable sliding surface is formulated and using Gao's reaching law, sliding mode control input is synthesized for the cart. By feeding suitable controlled motion to the cart, IFB is stabilized and the flexibility vibrations are also eliminated completely. The performance of SMC is compared with Proportional Integral Derivative (PID) control. Accuracy, robustness, speed and superiority of designed SMC is demonstrated in simulations.
