Ungrounded Generator Operaton In Off-Shore Utility Plant

Electrical & Electronics Engineering, Electronics & Communication Engineering
INTRODUCTION In offshore oil & gas installation, the electrical power system consists of a large distribution network, generally operating in island mode i.e., without grid support. For reliability and a compact utility plate form, power system is designed with multiple gas turbine and diesel generators, directly connected to 11kV switchgear, without generator transformers. Synchronous Generators are installed at Utility Plate form. They are driven by aero derivative gas turbine (aircraft turbine derivative applied to industrial application) and/or industrial gas turbine & diesel engines to supply un-interrupted reliable power to different plate forms to meet process requirement, refer to a typical single line diagram in Fig-1. During normal operation, GTGs supply power to the entire complex while all other DGs are not kept in operation, except for periodical operational testing. VT…

Modelling And Dynamic Analysis Of Wavespring

Electrical & Electronics Engineering, Electronics & Communication Engineering, Uncategorized
 INTRODUCTION Among the many types of springs, wave springs have attracted considerable attention this kind of long andreliable source of long lasting durability and considerable effectiveness than rest of the springs. An analytical model for stamped ring wave springs is proposed, Because of the particular shape of the spring in the un deformed configuration, the loaddeflection curve is found to be appreciably bilinear in character. A similar but less pronounced behavior is displayed also by the relationship between load and internal stresses.Wave springs are used to reduce the height of the spring and to produce the same end effect end that of a coilspring andalso obey the principles ofHooke’s law.When the vehicle moves in the high speeds there must also be a requirement to make analysis fatigue and dynamic loading…

                INTRODUCTION Electricity is a typical form of energy. It is a vital ingredient to upgrade the socio-economic condition and to alleviate poverty. Human civilization has advanced tremendously by versatile use of electricity. Electricity is necessary for all aspects of development. Proper and enough electricity supply results in a positive impact on the gross Domestic product (GDP), which is one of the key measures to understand the economy of a country. Currently about 63% of power generation of Bangladesh is based on natural gas. About 26% of its energy supply is based on imported oil and coal, 8% on diesel and the remaining 3% is hydroelectricity [1]. At present, consumers cannot be provided with uninterrupted and quality supply of electricity due to the…

Power Generation Using Speed Breaker

Electrical & Electronics Engineering, Mechanical Engineering, Uncategorized
                 INTRODUCTION In the present day scenario power has become the major need for human life. Energy is an important input in all the sectors of any countries economy. The day-to-day increasing population and decreasing conventional sources for power generation, provides a need to think on non-conventional energy resources. Here in this paper we are looking forward to conserve the kinetic energy that gone wasted, while vehicles move. The number of vehicles passing over speed breaker on road is increasing day by day. Beneath speed breaker, setting up an electromechanical unit known to be power hump, could help us conserving this energy and use it for power generation. The electrical output can be improved by arranging these power humps in series. This generated…

INTRODUCTION Mail is part of a postal system where in written documents, typically enclosed in envelopes, and also small packages, are delivered to destinations around the world. Anything sent through the postal system is called mail or post. In the late 1990’s the e-mail has dominant the mailing system which is always faster then postal system and cheap for users to communicate thought the world. The revolutions on mails have been drastic yet the usage of the conventional mailing system is widely practice thought out the world. Most of our important and official documents are send by the conventional .The research has found a new revolution in using newer technologies to alert the users on the event a mail is delivered, especially through the short message service (SMS) and e-mail…

Implementation Of Robotics In Transmission Line Monitoring

Electrical & Electronics Engineering, Electronics & Communication Engineering
INTRODUCTION   The power generating capacity of our country is very low but conversely the consumption rate is very high as a result of which the demand for power has increased. So it has become necessary to reduce the losses in order to obtain efficient power transmission. In order to achieve this, transmission lines have to be monitored in real time. The simplest form of power lines consists of one conductor per phase hung on insulator string which can be of either suspension or strain type. However in bundled power lines there is more than one conductor per phase. The inspection of power lines are difficult and dangerous for a human to perform due to the nature of their location and also due to the complexity of the power system.…

Intelligent Accident Spot Detection Using GPS And GSM

Electrical & Electronics Engineering
CHAPTER 1 INTRODUCTION   In the recent years the population and the technologies are increasing enormously, due to this the usage of vehicles are also increasing. Due to the increase in population the usage of vehicles are also increasing and at the same time the occurrence of accident is also increasing. Due to this the value of human life is also ignored. No one can prevent the accident but can save their life by expediting the ambulance to the hospital on time. For this a new vivid scheme has been introduced called the Intelligent Transportation System (ITS). The human life can be saved by implementing this method. Now-a-days it’s very difficult to know that an accident has occurred and its much more difficult to find the location of the accident.…

An In-shoe Harvester with Motion Magnification for Scavenging Energy from Human Foot Strike CHAPTER 1 INTRODUCTION Recent advances in communication technology and electronic engineering have resulted in the rapid development of wearable or portable devices. Although these advanced devices make daily life more convenient, their lithium batteries require frequent recharging, which creates other types of inconveniences. Therefore, sustainable power sources should be found for portable devices to reduce their dependence on external electric sources. In recent years, energy harvesting from ambient vibration or kinetic motion has attracted a lot of attentions. For example, novel energy harvesting mechanism to scavenge energy from vehicle vibration ,a harvesting device embedded in a vehicle tire to harvest rotational vibration, and a shear-mode harvester to harness non rotational vibration. Similarly, there is vibration or kinetic…

Integrated Boost Resonant Converter For Photovoltaic Applications

Electrical & Electronics Engineering
Integrated Boost Resonant Converter For Photovoltaic ApplicationsAN AN INTEGRATED BOOST RESONANT CONVERTER FOR PHOTOVOLTAIC APPLICATIONS CHAPTER 1 INTRODUCTION Power conversion for PV applications, as opposed to more conventional dc –dc converter configurations, requires an adaptable system that is capable of responding to a wide range of input voltage and current conditions. PV voltage varies significantly with panel construction and operating temperature, while the PV current changes largely due to solar irradiance and shading conditions . If a converter is designed only for high peak efficiency, oftentimes the range of conditions common to many PV installations will force the converter into another operating region where it is much less efficient. The ability to maintain high-efficiency energy conversion over a wide range of conditions is a continual challenge. In many cases, extending…
