Speed avoidance logic for a variable speed wind turbine

摘要: A variable speed wind turbine is controlled in a way which avoids the lingering at critical would otherwise tend to cause excessive vibration. The disclosed method and apparatus increases selected rate with respect generator output power except vicinity of speed. changed different slower embodiment, avoid commanding After or decreases beyond point, deliberate discontinuity command signal induced. rapid change through accompanied by corresponding change. If increasing below speed, stepped higher level just before reaching will rapidly increase quickly pass while decreases. Similarly, if decreasing above lower decrease increases.
