1. SMART GRID TECHNOLOGY: THE FUTURE OF POWER MANAGEMENT

AUTHOR NAME : Pankaj M. Dhote, Roshankumar V. Wavare, Akash A. Gophane

ABSTRACT : The existing Power Grids are antiquated, congested and inefficient in many ways and it does not take full advantage of new automation technologies that for example can prevent an outage or restore power much faster after an outage. It does not take advantage of new materials which can make the equipment throughout the grid more efficient. This technology proposes a method for better implementation of smart grids that integrates technologies of advanced sensing, control methodologies and communication capabilities into the current power grids at both the transmission level and distribution levels. In principle, the smart grid is an upgrade of the common electricity grids. This upgrade is expressed in the ability to operate in conditions of uncertainty in order to route the power supply in an optimal way that responds to a wide variety of situations, to encourage users in off-peak hours and charge premium rates from consumers who use energy during peak hours. The key to this capability is fast, accurate and two-way transmission of information between all parts of the grid. Situations that require fast response can occur at all parts of the grid – at the chain of production, transmission and consumption. The source of the event could be in the environment (sudden cloudiness that decreases solar power, or a very hot day that increases the demand for air conditioning), in parts of the grid itself (sudden failures, the need for proactive maintenance) or in the demand (work hours compared to hours of rest). Smart Grid is important as it will take us towards energy independence and environmentally sustainable economic growth. Growth of Smart Power Grid in India will slowly but surely take us towards fulfilling the dreams of former President Dr. A.P.J. Abdul Kalam, “Energy for all and Energy forever”

2. STUDY OF FAULT DETECTION IN TRANSMISSION LINES USING WAVELET AND CONTOURLET FEATURES

AUTHOR NAME : Ms. Aishwarya Lokhare, Ms. Rashmi Sing

ABSTRACT : Transmission line protection is an important issue in power system engineering because 85-87% of power system faults are occurring in transmission lines. This paper presents a technique to detect and classify the different shunt faults on a transmission lines for quick and reliable operation of protection schemes. Discrimination among different types of faults on the transmission lines is achieved by application of evolutionary programming tools. This work evaluates a new method for faults detections in transmission lines in HVDC systems. The proposed method uses voltage and current synchronized data. The HVDC systems are simulated using MATLAB software. The method for detection of faults in transmission line uses a self-adaptive threshold and presents a redundancy, which allows the detection of faults even in situations where loss of either voltage or current signal occurs. A monopolar and a bipolar system are simulated using Simulink/MATLAB®. Results might show that percentage errors are lower than 0.01% for all analyzed cases in the monopolar system and lower than 0.5% for all analyzed cases in the bipolar system. We plan to extend the system by adding contourlet transform for adding better accuracy of fault detection.

3. STUDY OF UNIFIED POWER QUALITY CONDITIONER (UPQC) TO ENHANCE POWER QUALITY

AUTHOR NAME : Mr. Tushar Kadwe, Ms. Rashmi Sing

ABSTRACT : In this project the work is propose for power angle control (PAC) to improve power quality (PQ) in distribution system. This algorithm reduces mathematical complication and its response time. It has aimed to make the designs of controller. The new concept is incorporates on triangle rules of vector addition/subtraction. The mathematical approach makes the algorithm efficient and comprehensive. The shunt voltage source converter (VSC) of unified power quality conditioner (UPQC) is controlled using instantaneous symmetrical component theory (ISCT). The ISCT enables UPQC to handle unbalanced and non-linear loads. The complete phasor diagram has been shown for various voltage conditions. A vector addition and subtraction-based mathematical calculation has been derived for estimation of different parameters of the proposed system. Proposed PAC can improve PQ in four wire distribution system with maximum utilization of series VSC of UPQC. A simulation study for voltage sag/swell with the new algorithm for PAC verifies the improved performance of the system. Results have been discussed in detail.

5. “ONLINE CLINIC APPOINTMENT SYSTEM

AUTHOR NAME : Ms. Kavita G. Bramhankar, Shikha Y. Somkuwar, Samiksha B. Kamble, Krutika R. Kuthe, Megha R. Gaikwad, Rani Surjuse

ABSTRACT : Health care is a fast growing industry in the world. Appointment scheduling is one of the key processes in this health industry. This paper focused on on-line appointment system for clinics. The objective of this thesis is to maximize patients’ preferences and the number of patients seen during normal business hours. This is a multi-objective problem to balance the tradeoff between overtime and patients’ preferences. To achieve the objective, a simulation model was built to compare four policies proposed. Emergent patient were always assigned to the same day they requested appointment. In the basic policy, non-emergent patients are assigned to their first preferred date until the reserved capacity for non-emergent patients is full. In Naïve policy, non-emergent patients are always assigned on their first preferred day. Non-emergent patients were assigned based on daily reserved capacity in Policy In forecasted the expected number of patients to be scheduled for each day and assigned patients to a highly preferred day with lower number of patients scheduled or forecast to be scheduled. Based on simulation results, it was found that most of non-dominated solutions were close both minimum objective values, so policies proposed were helpful for the clinics to balance overtime and patients’ preferences.

6. FAULT DIAGNOSIS OF AN INDUCTION MOTOR THROUGH MOTOR CURRENT SIGNATURE ANALYSIS, FFT, DCT & DWT ANALYSIS

AUTHOR NAME : Ms. Poonam Mandhalkar, Ms. Rashmi Sing

ABSTRACT : The paper is focused on one of the important technique practised under Condition Based Maintenance (CBM) procedure, which is known as Motor Current Signature Analysis (MCSA). The technique proposes the study of side-band frequencies, which are generated due to fault conditions within the machine. These side-band frequencies are later analyzed using Fast Fourier Transforms (FFT) and Discrete Wavelet Transforms (DWT). In the present work, the two different fault conditions namely Broken Rotor Bar (BRB) and Stator Winding Fault (SWF) are jointly analyzed, as a novel approach. The results have been compared with the fault diagnosis of healthy machine. This contribution can be helpful in further carrying out study on prognostics of the machines, and in reducing the unscheduled breakdown while increasing the reliability of the machine.

7. A SOLAR POWER GENERATION SYSTEM WITH A SEVEN-LEVEL INVERTER

AUTHOR NAME : Mr. Yuvraj Hari Chavhan, Ms. Rashmi Singh

ABSTRACT : This project proposes a new solar power generation system, which is composed of a dc/dc power converter and a new seven-level inverter. The dc/dc power converter integrates a dc-dc boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-level inverter is configured using a capacitor selection circuit and a full-bridge power converter, connected in cascade. The capacitor selection circuit converts the two output voltage sources of dc-dc power converter into a three-level dc voltage, and the full bridge power converter further converts this three-level dc voltage into a seven-level ac voltage. In this way, the proposed solar power generation system generates a sinusoidal output current that is in phase with the utility voltage and is fed into the utility. The salient features of the proposed seven-level inverter are that only six power electronic switches are used, and only one power electronic switch is switched at high frequency at any time.
