This thesis introduces the Thyristor Controlled Reactor (TCR) as a reactive power compensator. The design of TCR is introduced to compensate the varying load from the full inductive to the full capacitive. The techniques of the reduction harmonics are introduced. Also, the comparative study for the three types (i.e. star, delta, and hybrid) is introduced. The reactive power calculation is based on the d-q frame to be fed as an input to the controller. The Fuzzy Logic Controller (FLC) is designed to control the TCR system.The simulation of three topologies of the TCR systems is presented. The simulation results cover the open loop and the closed loop (FLC). The results of different loads which are controlled by FLC are given.The FLC controller proved a very good behaviour in both transient and steady state for controlling the TCR system. Finally, the hybrid TCR system proved a better solution for the THD in the most controlling range.
