Abstract:-As the population increases and people continue to demand a higher standard of living, the demand for energy also continues to increase. Thus there is a rapid growing interest in renewable energy, such as fuel cells and photovoltaic systems in the distributed power system architecture. Innovative topologies for renewable energy conversion systems that integrate with electric grids and energy storage systems are being proposed, each with limited modes of operation for the various needs in smart grid applications. In the view of this, bidirectional power flow plays vital role in grid connected systems. In vehicle-to-grid (V2G) systems, electric vehicles interact with the grid as distributed energy storage systems that offer many potential benefits. As an energy Interface between a vehicle and the grid, the bidirectional converter plays a crucial role in their interaction. Its reliability, safety, cost, efficiency, weight, size, harmonics, and other factors are of essential importance for V2G realization, especially for on-board operations. Beyond the common existing topologies for bidirectional converter, this paper brings out a comparative study of different types of bidirectional converter which are used in grid connected systems with highlighting the features of each converter for rooftop solar generation and hybrid power system in small scale renewable generation.

Abstract:-The objective of ambient intelligence is to create an intelligent daily space, which is immediately usable and integrated into our homes, our offices, our roads, our cars, and everywhere. This new concept must be invisible; it must blend in with our normal environment and must be present when we need it. One of the applications of this concept consists of providing our cars and roads with capabilities to make the road more secure (information about the traffic, accidents, dangers, possible detours, weather, etc.) and to make our time on the road more enjoyable (Internet access, network games, helping two people follow each other on the road, chat, etc.). These applications are typical examples of what we call an Intelligent Transportation System (ITS) whose goal is to improve security, efficiency and enjoyment in road transport through the use of new technologies for information and communication (NTIC). In this project we are using GSM/GPRS vehicle tracking system and vehicle to vehicle communication system. Vibration sensor detects the accident and using GSM technology it sends the message to another vehicle. If in the case of accident we can detect the location and find the latitude and longitude value. Traditional traffic management systems are based on centralized infrastructures where sensors are implemented along the road, collect information on density and traffic state and transmit this data to a central unit to process it and make appropriate decisions.

Abstract: An IC constitutes area of microelectronics in which many electronic components are combined in to high density modules. IC’s, the main component of each and every electronic circuit can be used for wide variety of purposes and functions. IC consists of active and passive components such as resistors, capacitors, transistors on single chip which reduces size of system, power consumption and cost of overall system. But sometime due to faulty ICs the circuit doesn’t work. It is lot work to debug the circuit and confirm whether the circuiting is creating problem or the IC is faulty. So the proposed project is designed to confirm whether the IC under consideration is properly working or not. The proposed project can be used to check the IC’s of 74 series at gate level. The digital integrated circuit (IC) tester is implemented by using the microcontroller PIC 18F4550. The microcontroller processes the inputs and outputs and displays the results on a Liquid Crystal Display (LCD). The basic function of the digital IC tester is to test a digital IC for correct logical functioning as described in the truth table and/or function table. The designed model can test digital ICs having 14 or 16 pins. Since it is programmable, any number of ICs can be tested. This model applies the necessary signals to the inputs of the IC, monitoring the outputs at each stage and comparing them with the outputs in the truth table. Any discrepancy in the functioning of the IC results in a fail indication, displays the faulty and good gates on the LCD. The testing procedure is accomplished with the help of keypad keys present on the main board design. The test has been accomplished with most commonly used digital IC's, mainly belonging to the 74 series. The design is flexible. We can add extra ICs and subroutines to test any other IC in the 74 series.

Abstract: In the present scenario, the rapid growth of technology has not only made our lives easier but the enormous growth of technology has also resulted in various traffic hazards and road accidents which has lead to a huge loss of life and property due to the various poor emergency facilities. India is one of the most accident-prone countries in the world with a record rate of more than 3 lakhs of road crashes every year. In such highly populated countries like India , everyday people lose their lives because of accidents and poor emergency facilities. These lives could be saved if medical facilities are provided at the right time. According to the literature survey we have found that there has been an increase of 4% in the total number of death rates caused by the road accidents during the period 2011-2014. As per the national crime records bureay (NCRB) in the year 2011 there were 440,123 road accidents resulting in the death of 136,834 people. This paper proposes a new dimension in order to allow early response and rescue of accident victims thereby saving the lives and properties. This system uses the capability of GPS and GSM along with the android phone for providing a solution which can be used to precisely detect the accident spot and to send the emergency notification to the nearby hospital’s ICU and to the victim’s relatives. This system can easily be fitted in the vehicle , its basic operation includes the vibration sensor which detects the accident and in turn sends the signal to arduino. The arduino then takes control and starts collecting the coordinates from GPS which are the sent to the emergency system by using the GSM module.

Abstract: Modern technological development in automobile industry has drastically improved people’s way of living; therefore there is a need for monitoring of vehicles to heighten its longevity. Mortality rate is also on the rise due to the lack of timely and proper medical attention. Continuous health monitoring of patients using wearable and implantable body sensor networks will increase detection of emergency conditions during health crisis. By integrating vehicle tracking and continuous wireless patient monitoring system; we can enhance safety during travel. This system is user friendly, easily installable, easily accessible and economically viable. The conventional system of tracking using battery operated radio frequency identification (RFID) is only suitable for small range. To overcome this, GPS and GSM technologies are used which will receive the location coordinates and provides real-time information which can be observed from any other remote location. The established health monitoring system is not compact and understanding the output analog signals is a tedious task. Hence, in the designed health monitoring system patient’s physiological signals are acquired by the sensors attached on the patient body; if there are any abnormalities then a notification is sent and the vehicle is turned OFF using relay.

Abstract:-The aim behind the development of the project is to limit the current at starting of motor and to develop the high starting torque. Here a Programmable Logic Controller is used which will be programmed as per our need. We have designed a control panel and programmed the PLC according to our need. The motor starts with high rotor resistance and as time elapse the rotor resistance will be shorted and the motor runs at rated speed. The resistance has been cut from the rotor in three parts in three different time intervals. The process of management of time and controlling of relays is the function of the PLC. Depending on PLC output, the relays will get shorted and the resistance will be removed from the rotor terminal.

Abstract:-Requirement of electricity is increasing day by day, to fulfill the demand more power plants either they are conventional or renewable are also growing in numbers consequently. Extracting the power from power plants and to supply the load more transmission and distribution lines are needed, this makes the power system more bulky and sensitive to disturbances. Moreover the installation of new lines is not an easy task as there are some limitations due to financial and right of way aspects, so the growth of such lines is slower than expected. More and more power flowing through the existing lines touching there maximum thermal limit or the stability limits of generators. A small disturbance (series / shunt faults, outage of generators etc.) in power system can cause complete grid failure. FACTS devices are the best solution of such problems as they can maintain reactive power level in power system either by supplying or absorbing it. In this paper impact of Static VAr Compensator (SVC) on Rajasthan Power System is presented using Mipower simulation tool.
