Comparison of current-limiting strategies during fault ride-through of inverters to prevent latch-up and wind-up [PDF]
Transient stability of a power network requires that generators remain synchronized and return to normal power export once a fault is cleared. For inverter-interfaced generators, one must ensure that current and voltage limiters do not latch-up and that ...
