Abstract:

介绍了网络化AGC系统的结构以及网络时延的特性，讨论了传统水电站AGC系统的模型。通过对网络时延模型及其仿真模块的分析，建立了考虑网络时延的新AGC系统模型。运用MATLAB/Simulink软件进行仿真模拟，结果表明采用网络时延的新模型对网络时延具有较好的控制性能，可以达到较为满意的控制效果。
The structure and the network delay characteristics of networked AGC system are introduced and the models of traditional hydropower station AGC system are discussed in detail. Based on the analysis of network delay model and its simulation module, a new AGC system model considering network delay is proposed. Simulating by using MATLAB/Simulink software shows that the new model can achieve satisfactory control effect, which has a good control of network delay.
