Governor of low frequency oscillation stabilizer

The present invention provides a low-frequency oscillation stabilization governor comprising: sequentially connected state feedback controller, and a filtering module limiter module; state feedback controller connected to said system output power, the adjustment limiter module connector speed system; state feedback controller of the current signal for the electric power system generates feedback suppression control signal, a filter module according to the set frequency, the transfer function by filtering out the state feedback controller outputs a control signal suppression control signal frequency is less than the set frequency; means for clipping the amplitude of the output signal of the filter module in the set range limit, and delivered to the transfer control signal through limiter speed system, speed control system generates positive damping moment. Governor of the above-described low frequency oscillation stabilizer can reduce the adverse effect feedback controller generates a control signal state of the power system, and improve the efficiency of the normal operation of the system.
