Reseach on AGC system based on transfer controller

针对传统的控制器在满足控制复杂系统响应快速性、准确性和鲁棒性等方面存在较大不足等问题,通过优化经典控制器增益值,提出一种基于传递函数控制理论的自动发电控制系统控制方法,首先运用动态教与学技术优化控制器参数,控制了频率偏差和区域间联络线净交换功率增量,并缩短了调节时间,然后通过模拟仿真两区、三区及大扰动系统,并与几个经典控制器的性能进行对比分析,控制效果表明传递控制器在自动发电控制系统具有良好的灵敏性和鲁棒性,对于研究自动发电控制具有很好的利用价值。

The conventional controller has significant shortcomings in terms of its rapidity,accuracy and the robustness of the complex system response.Through the optimization of the classical controller gain value,a control method of the automatic generation control system based on the transfer function control theory is proposed.Firstly,the dynamic teaching-learning techniques were applied in the optimization of the controller parameters,the frequency deviation and the increment of the tie line transition net interchange power were controlled,the settling time was also shortened.Then the two-areas,three-areas and large disturbance system were simulated,and a comparison was made in terms of the performance of several classic controllers.The control effects show that the transfer controller in the automatic generation control system has good sensitivity and robustness,and it has good utilization value for the study of automatic generation control system.
