摘要
在Zaborsky提出的电力系统观测解耦状态空间模型的基础上,进一步考虑励磁和调速系统的作用,建立了适合于暂态稳定综合控制的数学模型,并导出了励磁和快关汽门综合非线性最优变目标控制规律。这种控制策略首先按最大能量耗散原理确定控制目标,然后才驱动系统到达所希望的稳定平衡点。该控制策略仅需获得局部信息,能形成闭环反馈控制,因此容易在线实现。用一个4机6母线系统进行数字仿真。
A nonlinear optimal variable aim controller for multimachine power system transient stability is presented in this paper. The controller is based on an optimal aim strategy and on observation decoupled state space model, which includes fast valving and exciting system. The control strategy needs only local information and is easily implemented by feedback loop. The results of a test system simulation show that the controller is effective to enhance transient stability.
