Abstract:
linearized space state model is established in consideration of open channel water level fluctuations, which is transformed to transfer function to describe small fluctuation in hydropower station. Effect of water level fluctuations in tail water open channel on regulating system stability region was analyzed based on Hurwitz stability criterion. The results show that open channel has slight influence on stability range in hydropower station without tailrace surge chamber; length and depth of open channel has an evident influence on stability region in in hydropower station with tailrace surge chamber, and water level fluctuation in open tailrace tunnel make for the stability of small fluctuation transient process.
