Abstract
In order to be economically competitive, various
control systems are used in Wind turbine. These systems makes
the wind turbine to work efficiently and produce maximum
output at different speed. In this paper an adaptive control
based on radial-basis function neural network are used for
different operation of variable speed wind turbine including
torque control at lower speed, pitch control at higher speed and
smooth transition between these two modes. The adaptive
neural network control approximates the nonlinear dynamics of
wind turbine based on input/output measurement. One of the
most important features in the smart gird is to integrate the
state-of-the-art communication technologies to increase the
electrify generation. In offshore wind farms, data
communications would rely on wireless techniques. The
wireless communication technology has several advantages
over the wires or meter counterpart. However, the impact of
atmospheric turbulence on wired must be well understood first.
In this project, the performance of wireless links subject to
weak influence in generator, turbine is monitored. The metrics
are analytically and numerically evaluated.

I.Introduction
Wind power has become the world’s fastest growing renewable
energy resource. The worldwide wind capacity is increased
upto 120 GW.Wind power becomes as a major utility source, it
is complex to understand the operation of power system in
order to improve both quantity and quality of wind power
generation. In Wind turbine there is a different types of failure.
Therefore, before exploring condition monitoring and fault
diagnostic methods in wind turbines, the different kinds of
failures, as well as their downtime consequences, are reviewed
[2-7]. Of course, obtaining high power from wind turbine is
complex it requires high performance monitoring-.
Monitoring systems collects data from the components of Wind
turbine such as Generator, gear box, main bearing, shaft, yaw
system.
The purpose is to minimize downtime and maintenance cost
while increasing energy availability and extending the lifetime
service of wind turbine components. Condition monitoring
system monitors all the components with a minimum number of
sensors. Manufactures and operators are working hard to
develop the advanced condition monitoring system to develop
the efficiency and prevent from failures.
A wind turbine consists of many components that causes
different types of failures, in which some of the them will
frequently occurs that can be identified by comparing among
them,it is necessary to know downtime. The resultant economic
loss which is caused by the downtime of a particular component
in this work, the economic losses caused by wind turbine
subassemblies are approximated by the downtimes caused by
failures. Figure 1.1 gives the annual average downtimes of
major wind turbine subassemblies according to the LWK
survey of more than 2000 wind turbines for 11 years
[10].Neural networks are powerful methods for approximation
of input output mappings. Many works [6],[7] suggested that
the condition can be monitored by integrating both Trend
master Pro and Snapshot offerings is signal processing
technology, which can be particularly beneficial. The remainder
of this article explores the technology and its benefit in more
detail to relate wind turbine. Condition monitoring of Wind
turbine frequently gives better maintenance management and
increased reliability[2]
