摘要:为了解决水轮机系统中频率受负荷影响产生波动的问题，在自动发电控制（automatic generation control， AGC）的基础上，提出基于广义预测控制（generalized predictive control， GPC ） 的水轮机系统频率控制策略。首先，建立连续系统传递函数模型；然后，结合GPC控制算法的滚动优化、反馈校正和有限时域步进迭代算法对搭建数学模型仿真求解，得到性能优于传统 PI控制的调节策略；最后，将提出的GPC控制策略分别采取不同的设定值分析在不同情形下的优化性能。结果表明，GPC用于水轮机调节系统，可得到良好的输出响应，有效解决电力系统的调频问题，且增强了系统的鲁棒性。

Abstract:In order to solve the problem of frequency fluctuations affected by loads in power systems ,on the basis of automatic generation control(AGC),a frequency control strategy based on generalized predictive control(GPC) theory was proposed. First, the transfer function model of the continuous system was built. Then, the simulation scheme was built by combining the receding horizon optimization of the GPC control algorithm, feedback correction and finite time domain iteration ,and the adjustment strategy with performance better than traditional PI control was obtained. Finally, different setting values were adopted in the proposed GPC control strategy to further analyze the optimized performance in different situations. The results showed that GPC being used in the hydro-turbine regulation system could obtain a good output response ,the frequency modulation problem of the power system could be solved effectively,and at the same time the robustness of the system was enhanced.
