INTRODUCTION AND SCOPE OF WIND TURBINE POWER PLANT
This report summarizes the results accomplished at the time of project conclusion. Before
WECC‐WGMG embarked on working on dynamic models of wind turbine generators,
availability of appropriate models for representation of WPPs were limited. For the most part,
only manufacturer‐specific user‐written models were available on a limited basis (through nondisclosure
agreements) for the purposes of conducting interconnection studies. These types of
dynamic models are developed in full detail, including information deemed to be proprietary
by the turbine manufacturers. Manufacturer‐specific models sometimes are not fully
integrated into the standard model library of simulation software, which leads to model
maintenance and compatibility issues. Also, difficulties sometimes occur when we want to
study an area with several WPPs from multiple manufacturers. Compatibility issues, limited
access to models and long technical support iterations often results in long delays to complete
the studies. After projects are completed, the proprietary nature of the models prevents their
inclusion in the WECC standard dynamic database for the purposes of conducting regional
studies.
With funding from WECC, CEC and DOE, and support from several organizations including
DOE and Sandia, the WECC‐WGMG completed the first phase of the effort to develop and
implement wind turbine generator (WTG) dynamic models. The WECC dynamic models are
intended to be generic in nature and non‐proprietary, and thus are readily available for use.
Generic models allow for unique characteristics of WTGs from different manufacturers to be
represented by adjusting model parameters. These WECC dynamic models are currently
available in the library of the PSLF (developed by GE) and PSSSE (developed by Siemens PTI).
Default input data for each models is also provided. The generic models are also being
implemented in two other software platforms: Operation Technology ETAP, and Powertech
Labs DSA Tools.
MODIFICATION IN WIND TURBINE
Now , how our Modified VWT comes over the disadvantages of older wind power harnessing mathods –
1. MWT will be able to work on minimum available wind speeds , so here chance of no power generation will so rare .
2. MWT will be installed on higher altitudes and this system will take too less space , so the landscape will be untouched .
3. MWT will be pretty less noisy and they will be on higher altitudes so the noise pollution will zero .
4. MWT will pleasant to look on higher altitudes .
5. In India , govt. is not able to provide sufficient electricity in rural areas . So MWT will become a good option for fulfill the domestic electricity requirement .
Technical aspect of the proposed MWT -
1. Air speed and kinetic energy study with turbulence.
2. Turbine selection & design considering aerodynamics as well as weight
3. Alternator design considering r.p.m & weight
4. Balloon design considering payload,aerodynamics along with minimum cost.
5. Gear mechanism used in turbine.
DISADVANTAGES OF WIND TURBINE POWER PLANT OVER MODIFIED WIND TURBINE
1. The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. There will be times when they produce no electricity at all.
2. Many people feel that the countryside should be left untouched, without these large structures being built. The landscape should left in its natural form for everyone to enjoy.
3. Wind turbines are noisy. Each one can generate the same level of noise as a family car travelling at 70 mph.
4. Many people see large wind turbines as unsightly structures and not pleasant or interesting to look at. They disfigure the countryside and are generally ugly.
5. Large wind farms are needed to provide entire communities with enough electricity. For example, the largest single turbine available today can only provide enough electricity for 475 homes, when running at full capacity. How many would be needed for a town of 100 000 people?
Abstract and key features
Abstract:-
“ In now days ,It became our necessity to use unconventional , renewable & clean energy sources . “
Energy is the key input to drive and improve the life cycle. Primarily, it is the gift of the nature to the mankind in various forms .The consumption of the energy is directly proportional to the progress of the mankind . With ever growing population , improvement in the living standard of the humanity, Industrialization of the developing countries , the global demand for energy is expected to increase rather significantly in the near future . The primary source of energy is fossil fuel , however the finiteness of fossil fuels reverse and large scale environmental degradation caused by their widespread use , particularly global warming , urban air pollution and acid rain , strongly suggests that harnessing of non – conventional , renewable and environment friendly energy resources is vital for steering the global energy supplies towards a sustainable path .
