电力系统暂态稳定预测控制的研究

STUDY ON PREDICTION CONTROL FOR TRANSLENT STABILITY OF POWER SYSTEMS

提出了一种新的提高电力系统暂态稳定性的控制方法：预测控制方法。该方法是用实测和预测分析相结合来取代传统方法中的解析推理，即以对发电机电磁功率的实时测量来预测系统的稳定性，并根据预测分析的结果进行超前控制。数值仿真证实了本控制方法的合理性和有效性。

A new prediction control method,in this paper,is proposed For improving transient stability ofpower systems.This method uses the combination of the practical measurement with simple prediction analysis to replace the traditional deductive calculation.By using this method ,the stability of power systems canbe predicted through real-time measurement of the electromagnetic power of generator and load control isthen taken according to the predicted result.Numerical simnlation results have shown that the proposedmethod is effective and practically feasible.
