摘要
介绍了对于远距离送电的发电厂当电力系统发生危及其稳定运行故障时 ,利用其发电机感受到的角加速度及其变化率、有功功率及其在电力系统故障时的突变量等特征量进行多级智能控制的方法 ,及其在相关工程实践中计算、试验结果。通过此控制原理实现的控制过程具有一定的实时性 ,且简单。
For the power plants with long distance transmission lines, when the power systems tend to losing the stability caused by faults, in terms of the angle acceleration and the acceleration ratio of generators , the characteristic variables, such as the active power and other suddenly changing variables, are controlled in a multi stage. The principle of the intelligent stability control is proved in practice. The process of the intelligence control is a real time control , and it is simple and easy for use.
