Design and Development of a Fuzzy Logic Implementation of a Microcontroller Based FACTS Employing Thyristor Controlled Reactor/ Thyristor Switched Reactance for Power Quality Management
Keywords:
Capacitive load, FACTs, Ferranti effect, Inductive load, PWM, TSR, TCRAbstract
The main power quality eccentricities are occurred by Ferranti effect, short-circuits, voltage sparks,
voltage swells harmonic distortions, voltage sags and transients occur by switching of load. The
fundamental sinusoidal waveform of current will change when we are using a non-linear load in a
power system. Power quality are modify reactive power problem such as power factor lagging due to
inductive load or voltage multiplication using Ferranti effect by Thyristor Switched Reactance (TSR)
and Thyristor Controlled Reactor (TCR) are two of shunt FACTS(flexible AC transmission system)
devices have been used as an alternative to fixed shunt capacitors and fixed reactors in power
systems. Application Fuzzy logic on 8 bit microcontroller to sense power quality and employ
corrective action and system is designed using fuzzy logic controller and MAT Lab coding.
