摘要
变电站电压无功自动控制系统是一个多输入多输出的复杂系统,其精确的数学模型难以建立,导致采用常规的方法很难对其进行有效的控制.通过分析变电站电力系统,给出了变电站电力系统模型,并设计出了相应的仿人智能控制器,最后以35 kV变电站为实验模型,利用MATLAB进行仿真,结果表明在不同负荷状况下,该控制器改善了变电站电压合格率和无功功率.
The substation voltage and reactive power automatic control system is a multiple input and multiple output complex system and it is difficult to build its mathematic module so it is not easy to get effective control of it with normal control method. Through analyzing the substation power system, this paper brings forward the module of substation power system and designs the human-simulated intelligence controller. Finally, it chooses a module of 35kv substation and makes simulation experiment of it by using MATLB. The result shows that the controller is successful in improving the voltage quality and reactive power at various load conditions.
