Fault Ride – Through Capability Enhancement of Offshore Wind Farms Connected via VSC-HVDC Transmission

SEEE DIGIBOOK ON ENGINEERING & TECHNOLOGY, VOL. 01, MAY 2018 pp. (59-64)
Abstract– Voltage source converter (VSC)- based high voltage DC (HVDC) transmission is viewed as the eventual fate of offshore power transmission. This paper goes for giving a solid VSC-HVDC transmission system design between offshore wind ranches and inland grids. In this paper, an extensive limit, low-speed flywheel energy storage system (FESS) in light of a squirrel cage induction machine is connected in parallel with the VSC-HVDC at the grid side converter. The FESS is committed to surge control (because of power flow variation during the fault) retention rather than being dispersed as resistive losses. Since the time span of these surges is moderately little, it has been demonstrated that the flywheel can adequately relieve this issue. In this FESS converter model existed by using PI controllers in which will get good response of power leveling operation and under fault conditions of the systems and FESS offshore wind farms using the proposed Fuzzy logic controller. It helps the system improves power levels, the stability of the systems for under normal and abnormal operations compared to PI controller. A 132-kV 100-MW HVDC system is simulated utilizing MATLAB/Simulink during normal and fault conditions.
