本文提出了远距离输电系统中的大型汽轮发电机组的快速汽门的最优闭环控制方案.它不仅从理论分析上而且通过电力系统动态物理模型的实验证明了:按线性最优控制理论设计的快速汽门控制器,可使输电系统在瞬时性或永久性故障下的瞬态稳定极限及事故后的动态品质,均获得十分显著的提高与改善.本方案的一个重要特点是:可以区别和适应各种故障条件的变化,这是固定逻辑的开环控制方案所难以达到的.
In this paper, the optimal closed-loop control scheme for a large steam turbine generator set is proposed, which not only from the theoretical analysis but also from the dynamical physical model of the power system. The linear closed-loop control theory Of the rapid steam valve controller can make the transient stability of transient transmission system under transient or permanent fault and dynamic quality after the accident, have been very significant improvements and improvements.An important feature of this program is: you can distinguish And adapt to changes in various fault conditions, which is hard to achieve with fixed logic open loop control schemes.
