针对两区域互联电力系统在受到外界负荷扰动后系统负荷频率的变化规律,基于TBC-TBC联络线频率偏差的控制模式,先后利用经典的PID控制技术和前馈补偿控制技术,对两区域互联电力系统负荷频率的控制算法进行优化研究,使两区域的电力系统在突然遭受负荷扰动时能迅速可靠地减少频率偏差和联络线交换功率偏差,恢复系统的安全稳定运行。在MATLAB7.8.0/Simulink软件的仿真下,其结果表明,经过前馈补偿后的PID控制比经典PID控制具有更佳的控制效果和鲁棒性。

According to the rule of changes of the load frequency of the 2-area interconnected electric power system under external load disturbance,based on the TBC-TBC liaison line frequency deviation control mode,this paper uses classical PID control technique and feed-forward compensation control technique respectively to study optimization of the load frequency control algorithm of the 2-area interconnected electric power system,so that the 2-area power system may quickly and reliably reduce frequency deviation and liaison line exchange power deviation,and resume safe and reliable operation of the system when it suddenly encounters load disturbances. The result of simulation with MATLAB 7.8.0/simulink shows that the PID control after feed-forward compensation has a better and more robust effect than classical PID control.
