Coordinated Control of Wind Energy Conversion System during Unsymmetrical Fault at Grid

High penetration of wind power into the grid necessitates coordinated action energy conversion systems and grid. A suitable generation control is required to fulfill integration requirements, especially during faults. system using a pair voltage source converters with squirrel cage induction generator coupled turbine proposed provide fault ride-through threefold used for providing effective via machine side converter. The entire controlled such that remains connected even To implement action: (i) decoupled current controller placed in converter, which separately controls positive negative sequence currents arising converter capable eliminating double frequency oscillations at dc-link and, hence, real power, arises unsymmetrical faults; (ii) Reactive injection additionally provided by better support; (iii) vector technique along droop adjust speed torque resulting actuation pitch mechanism limit without shutdown turbine.
