Dynamic simulation control of electric power system based on fieldbus technology

介绍了一种基于现场总线的控制方案,利用数字技术取代传统的动态模拟控制方法。该方案结合动模系统的特点,通过组建多层通信网络,实现各种控制功能,同时,利用相应的组态软件编写人机界面,使上位机与主控制单元进行数据及控制命令交换,实现系统实时监控及远程控制功能。整个方案符合现场总线设计的基本思想,适合电力系统动态模拟系统的控制,可在很大程度上提高动模系统的控制水平,同时使系统具有灵活、可靠、易于扩展等特点。

A control method based on fieldbus technology is introduced,which adopts digital tech-nology instead of traditional dynamic analog control.Combined with the features of dynamic simulation system,it implements various control functions by building up multi-layer communication network.The configuration software is used to program the human machine interface for the data and com-mands exchange between the host and the main control unit to implement the real-time supervisory control and remote control.The method conforms to the basic design concept of fieldbus and fits to the dynamic simulation control of electric power system.It improves greatly the control level of dynamic simulation system and makes the system more reliable,flexible and extendible.
