【摘要】 采用图形控件绘制变电站控制与信号系统的图纸,通过分析图形控件连接关系、设备连接关系、电气部件连接关系,建立起通用的变电站控制与信号系统的仿真模型。针对模型拥有大量的开关性电气部件和相对独立的模块等特点,采用等效节点法、模块分割法、树梢消去法、局部调整法、分布式计算等手段,以提高其仿真的快速性。更多还原

【Abstract】 The graphical controls are used to plot the drawings of the control and signal system for substation. The connected relations of graphical controls, devices and electrical components are analyzed on the basis of the drawings, and as a result the common simulation model of the control and signal system for substation is established. With a view to the facts that the model is made up of many self-governed modules, and there are lots of on-off electrical components in them, such methods as equivalent-node, separate-module, treetop-elimination, partial modification and distributed calculating are applied to speed up the simulation.更多还原
