M. (EEE 02705 177) Design and successful operation of Wind Energy Conversion systems (WECs) is a very complex task and requires the skills of many interdisciplinary skills, e.g., civil, mechanical, electrical and electronics, geography, aerospace, environmental etc. Performance of WECs depends upon subsystems like wind turbine (aerodynamic), gears (mechanical), generator (electrical); whereas the availability of wind resources are governed by the climatic conditions of the region concerned for which wind survey is extremely important to exploit wind energy. This paper presents a number of issues related to the power generation from WECs e.g. factors affecting wind power, their classification, choice of generators, main design considerations in wind turbine design, problems related with grid connections, wind-diesel autonomous hybrid power systems, reactive power control of wind system, environmental aspects of power generation, economics of wind power generation, and latest trend of wind power generation from off shore sites.

(EEE 034 06099) In this thesis work a detail study on substation and its protection system has been done. An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Electric power may flow through several substations between generating plant and consumer, and may be changed in voltage in several steps. A substation that has a step-up transformer increases the voltage while decreasing the current, while a step-down transformer decreases the voltage while increasing the current for domestic and commercial distribution. The word substation comes from the days before the distribution system became a grid. The first substations were connected to only one power station where the generator was housed, and were subsidiaries of that power station. There some use protective device such as in a Circuit breaker, Relay, Isolator, Lightning arrester, Fuse etc. It is hoped that this work will be useful for future generation researches to find the relevant references to advance the research work in future.

( EEE 031 05838 ) Nuclear power station, the world is looking for nuclear power generation as the need of electrical power increasing dramatically. The reason behind this is, only small amount of source is more than enough to produce huge amount of power. In nuclear power station, heavy elements such as Uranium (U235) or Thorium (Th232) are subjected in a special apparatus known as reactor. Nuclear fission or nuclear fusions are the methods mainly used here. When any one of the above said process takes place, huge amount of thermal energy generated. This thermal power is used to generate high temperature steam. The steam runs the steam turbine which converts steam energy into mechanical energy. The turbine drives the alternator which converts mechanical energy into electrical energy. Only difference between thermal and nuclear power station is that nuclear source is used to generate heat. The advantage of this power station is that, only small amount of source is enough compare to thermal power generation. The main disadvantage is that, it is dangerous to human. If any accident takes place then the entire area will be affected. The radiation is more dangerous to human being. The disposal of nuclear waste is difficult process. In nuclear power stations, reactor is placed only below the earth level to avoid radiations. Thu, 01 Apr 2010 00:00:00 GMT http://182.160.117.219:8080/xmlui/handle/123456789/78 2010-04-01T00:00:00Z
