This paper proposes and designs two novels Fault Ride Through (FRT) controllers for maintaining Fixed
Speed Wind Generation system (FSWGs) stability during fault events. The first technique has been implemented
by increasing the wind turbine blade pitch angle with maximum possible rate to reduce the
mechanical extracted wind power and consequently suppress wind generation system acceleration.
The second FRT technique has been verified by adapting gear ratio of wind generation system to run
far from optimum maximum power point and help FRT process. Effectiveness of the two proposed FRT
techniques has been proven by accurate simulation of the most severe disturbance conditions. Also,
Results indicated that second technique gives faster response than the first one. Without employing
any FRT technique, FSWGs cannot keep its stability and the standalone Micro-Grid (MG) transfers to
the blackout mode. Implementation the two FRT techniques requires no additional hardware. Only, control
algorithms need little modification to deal with fault event and help FRT process. This fact makes the
two proposed FRT techniques are simple, practical and highly economical attractive.
