The paper describes an advanced approach to power quality enhancement with PMSG (Permanent Magnet Synchronous Generator) based DG (Diesel Generator) set feeding three-phase loads using STATCOM (Static Compensator) with fuzzy controller is proposed in this paper. Here we are using the fuzzy controller compared to other controllers i.e. The fuzzy controller is the most suitable for the human decision-making mechanism, providing the operation of an electronic system with decisions of experts. A 3-leg VSC (Voltage Source Converter) with a capacitor on the DC link is used as STATCOM. The reference source currents for the system are estimated using an Adaline based control algorithm. A PWM (Pulse Width Modulation) current controller is using for generation of gating pulses of IGBTs (Insulated Gate Bipolar Transistors) of three leg VSC of the STATCOM. In FLC, basic control action is determined by a set of linguistic rules. These rules are determined by the system. The performance of the system is analyzed on various types of loads under steady state and dynamic conditions. The DG set is run at constant speed so that the frequency of supply remains constant irrespective of loading condition. By using the simulation results we can analyze the proposed method.
