Abstract: Pulse regulation mode of monitoring system is widely used in power regulation mode of hydropower unit currently.For pulse regulation mode can’t meet speed and accuracy requirements of grid.The paper proposed a new regulation mode based on three-stage speed regulation method and power feedback mode.A series of field tests carried out in Fengtan hydropower station showed that power feedback model is superior to the pulse regulation mode.With power feedback mode of the three-stage speed regulation used,"power anti-regulation"can be effectively reduced and the regulation speed and accuracy can be greatly increased.Thus,it can be used in other hydropower station.
