水电站水体机电耦合振荡研究及对策

Study and Countermeasures on Water Body and Electromechanical Coupling Oscillation in Hydropower Station

水电站发电过程就是将水的势能转化为电能的过程,而水头决定了水的势能大小。一旦水电站水体发生振荡,必将引起功率的变化,而此时机电调节必然介入以维持功率恒定,最终形成水体机电耦合振荡。这会给水电站机电设备、大坝等带来严重危害。本文着力研究水电站水体机电耦合振荡的原因,并给出对策。

The power generation process of a hydropower station is the process of converting the potential energy of water into electric energy,and the water head determines the potential energy of the water. Once the water body of the hydropower station is oscillated,it will cause the change of power. Mechanical and electrical regulation is necessarily involved in maintaining constant power,finally formed the electromechanical coupling oscillation of water body. This will cause serious damage to the electrical and mechanical equipment and dams of hydropower stations. This paper focuses on the causes of electromechanical coupling oscillation in water bodies of hydropower stations and gives countermeasures.
