本文提出了一种多机电力系统分散非线性最优励磁控制的设计方法，重点是微分几何法。实现的控制律是通过纯粹的本地测量。此外，它是独立的电力网络的参数。对一个六机电力系统进行了仿真。结果表明，非线性最优励磁控制能够适应大扰动的情况。此外，本文还证明了线性化系统的LQR原理意义下的最优控制等价于原始非线性控制系统的准二次型性能指标意义下的最优控制。
A design method to lay emphasis on a differential geometric approach for decentralized nonlinear optimal excitation control of multimachine power systems is suggested in this paper. The control law achieved is implemented via purely local measurements. Moreover, it is independent of the parameters of power networks. Simulations are performed on a six-machine power system. It has been demonstrated that the nonlinear optimal excitation control could adapt to the conditions under large disturbances. Besides, this paper has verified that the optimal control in the sense of LQR principle for the linearized system is equivalent to an optimal control in the sense of a quasi-quadratic performance index for the primitive nonlinear control system.
