可控串补( TCSC)的自适应单神经元控制

电力系统是一个高阶、强非线性系统,其模型和运行参数的不确定性给各种控制器的设计带来极大的不便,智能控制方式通过人为构造一非线性映射与被控系统进行拟合,而不需要精确的数学模型,因此具有良好的控制特性。利用单神经元设计了可控串补(TCSC)控制器,并在单机———无穷大系统中和常规PID控制器的控制效果做比较,结果表明:基于单神经元的TCSC自适应控制系统对电力系统暂态稳定性具有良好的效果。

Study of adaptive control strategy of TCSC based on SNN

Because the power system is a high order and strong nonlinearity system, the uncertainty of its parameters and models makes a great difficulty in various controllers design. Intelligent control,however,has a remarkable control ability by establishing a nonlinear mapping between the controller and the object, without needing precise math model.Thus, a controller of TCSC based on the single neural network (SNN), called intelligent control method is designed, and the result is optimistic compared with the controller based on the conventional PID method.
