Electric vehicles (EVs) are a promising technology for achieving a sustainable transport sector in the future. This is because of their very low carbon emissions, high efficiency and flexibility in grid operation and integration. However, if several EVs simultaneously draw power from a charging station, this will result in a voltage drop for that particular phase of the distribution system. Further, the constant rise in demand for electricity has resulted in a more complex and interconnected system thereby, pushing the distribution system to operate closer to the boundaries of stability. In order to avoid any undesirable phenomena, it is essential to continuously monitor the different parameters in a distribution system such as voltage, current, power etc. An early indication can be obtained by closely monitoring the voltage stability indices of the different buses in the distribution system. This necessitates the development of different methods for measuring and detecting voltage collapse in bus bars prior to any undesirable phenomena. The primary goal of this dissertation is to develop a mathematical equation for obtaining the voltage stability indices (VSIs) of the buses in a radial distribution network (RDN) in the presence / absence of renewable penetration using the bus states. This will help in determining the bus that is most vulnerable to voltage collapse. Further, the placement of renewables is suggested in the system to improve the bus stability indices and as well as to maintain continuity of power flow in case of single branch outages. In this work, MATLAB based programming is performed on a distribution system using the forward backward load flow method to obtain the bus states. This information is then utilised to calculate the bus VSIs. A standard benchmark distribution system (IEEE 33 bus) is considered and the VSIs are plotted under different case studies..

In urban areas, electrical cables run underground instead of running over, because it does not affected by any adverse effect of weather such as heavy rainfall, snow, thunder storm. Whenever a fault occurs within the underground cable, it is difficult to detect the exact location of the fault for the repair process of particular cable. The proposed system found the point of the exact location of fault. The paper uses the standard concept of Ohm’s law i.e. when a low dc voltage is applied at the end of feeder through series resister (cable lines) then the current will vary depending on the location of the fault Short in the cable. This system uses an Arduino microcontroller and a rectified power supply. In this case, the current detection circuit in combination with the resister is connected to the microcontroller with the aid of an ADC device to represent the length of wire in Km. Error creation is performed by a set of switches. The relays are controlled by a relay exciter IC, which is used to check cable line. A 16x2 LCD is used to display information. Also one more feature is that using GSM the message of fault detection, location of fault and distance of fault from base station in kilometers this all information is send to base station. As soon as a fault occurs in a cable the buzzer produce the alarm to alert and to take an immediate action by field workers.

This is a solar tracking system which can be used as a power generating method from sunlight. This method of power generation is simple and is taken from naturalresource.This needs only maximum sunlight to generate power. This project help for power generation by setting the equipment to get maximum sunlight automatically throughout the year.This system is tracking for maximum intensity of light. When there is decrease in intensity of light, this system automatically changes its direction to getmaximum intensity of light.

Nowadays, with the proliferation of urbanization; the number of cars, taxis, buses, tracks etc. have increased considerably. Recent statistics reveal that over the past few years, the number of accidents has increased due to drowsiness, lack of concentration & fatigue due to long drives etc. Most of the accidents occur on highways due to sudden sleep of drivers due to long drives for hours. In this scenario, this project aims at designing a smart and automatic sleep detection system to alert the driver and make him awake by buzzing an alarm within fraction of a second after detecting the sleep/drowsiness.One camera will be installed to continuously monitor the driver’s face after the engine starts. If drowsiness is detected from the driver’s face, the controller will generate a control signal. The control signal will switch on a buzzer, which will alert all passengers including the driver. Hence, the probability of an accident can be reduced, thus saving lives.

DESIGN AND DEVELOPMENT OF FULL BRIDGE PHASE SHIFT DC TO DC CONVERTER FOR CCS2 DC FAST CHARGER APPLICATION

Nowadays in India, battery powered Electric vehicles (EV) gaining popularity due to the high cost of petroleum. Government is also encouraging the use of electric vehicle to reduce petroleum import and environmental pollution. Moving to an electric transportation model requires battery storage capable of supplying the energy and power demands of the vehicle. Li-ion battery technology has advanced significantly over the last couple of years, making EVs more cost effective and practical. The cost of the batteries has fallen to less than $120/kWh. Despite huge improvements in energy density of the Li-ion batteries (200-300 Wh/kg) and the significantly higher efficiency of the electric propulsion drivetrain, the driving range of EVs on one charge is still shorter than the range of the conventional gasoline vehicles due to the orders of magnitude larger (12,000 Wh/kg ) energy density of petroleum. In summary, despite the failing cost and major improvement in performance of Li battery limited energy density (compared to petroleum) still pose major challenges to more widespread EV adoption due range anxiety of Li battery. As result seamlessly recharge of EV batteries to extend the driving range during longer trips is a practical need. At present a key remaining challenge for the wide adoption of EVs is the lack of the charging infrastructure. Therefore, there is an urgent need for an EV charging infrastructure that will parallel the existing gasoline stations, particularly in regions where long-distance trips are common. In case of conventional AC chargers the charging speed is slow, due to the fact that AC current from the chargers is converted into DC current inside the vehicle using on board charger. This is necessary because a battery cannot be charged directly through an AC supply. DC fast chargers perform this conversion process outside the vehicle. This allows us to use large capacity converters since there is no size limit. However, designing and deploying such an EV charging infrastructure is complex, and must consider competing industry standards, available technologies, grid impacts, and cost. To reduce the cost, development of indigenous technology is necessary. This work is focused on this requirement. In this work design development of 10KW full bridge phase shift (FBPS) DC to DC converter is discussed. Starting from the working principle of the converter, simulation study, hardware design, PCB design and test result of prototype is presented in a systematic manner.
