Grid Connected Wind Energy Conversion System Using Unified Power Flow Controller

Yashaswini. T. | Poornima G. P | Vasantha Kumara T. M | T. R. Narasimhegowda


Abstract: This paper presents an improvement technique for the power quality of the electrical part of a wind generation system with a variable speed wind turbine generator; self-excited induction generator (SEIG) which aims to minimize the utilization of wind power injected into weak grids. In order to realize this goal; a dynamic Volt Ampere Reactive (VAR) compensator Unified Power Flow Controller (UPFC) has been proposed. UPFC is a combination of series Voltage Source Inverter (VSI) Static Synchronous Series Compensator (SSSC) and shunt VSI STAtic Synchronous COMpensator (STATCOM). Here Space Vector Pulse Width Modulation (SVPWM) ; voltage oriented controller and current oriented controller hysteresis current controller PWM techniques are proposed to control the inverter outputs of SSSC and STATCOM respectively. And in an attempt to minimize the percentage of Total Harmonic Distortion (THD) in the inverter current and voltage and to avoid poor power quality a LC filter is inserted between UPFC and grid. Here to show the effectiveness of the proposed model a grid connected WECS using UPDC is compared with grid connected WECS without UPFC. The improvement can be seen through the comparison of percentage of THD in both the case. This work is simulated through matlab.
