Alternative Braking Method for Small Scaled-Wind Turbines Connected DC Green House with Analogical Experiment on Blade Destruction

“…Faraday law of induction states that a magnetic field can produce a current in a closed circuit when the magnetic flux linking to the circuit is changing [8]. Equation 2introduces the mathematical expression of the Faraday law of induction, ε = -dΦ dt (2) where, ε and Φ stands for electromotive force and magnetic flux, respectively.…”

“…Assuming this magnetic flux induced on a copper plate and its resistor is RC and I is the induced eddy current on a copper plate. We can obtain the mathematical expression as (3), According to ohm's law, -ε =R c I eddy (3) From (2) and 3we can obtain the eddy current as the following equation indicates.…”

“…Nowadays larger scale wind turbines can produce up to 10MW and Small wind turbines can produce less than 100 kilowatts. However, management of the wind energy sources has been always challenging as it has a considerable effect on different aspects of the power system such as the power quality [2], power harmonics and inter-harmonics [3], power line communications [4], etc. In this regard, research topics regarding how to obtain a maximum power output for high speed wind input without destroying the small-scaled wind turbine system can be considered as one of the important research areas of the wind energy.…”

H-Infinity Control of an Adaptive Hybrid Active Power Filter for Power Quality Compensation

“…To control the series connected APF the reference vector should be generated and compared with the actual voltage vector [1]. The reference voltage vector given by Equation 21is generated by the following control block.…”

“…At the same time, the quality of the electric power supplied is also very important for the efficient functioning of the end user equipment. The term power quality became most prominent in the power sector and both the electric power supply company and the end users are concerned about it [1]. The quality of power delivered to the consumers depends on the voltage and frequency ranges of the power.…”
