摘要
定义了一种受控Ｐｅｔｒｉ网，并对其中冲突的避免问题进行了探讨。针对抽水蓄能机组运行工况较多、工况转换复杂的特点，采用了受控Ｐｅｔｒｉ网技术对抽水蓄能机组的运行状态进行建模及分析，并用可编程控制器（ＰＬＣ）加以实现。
A kind of Controlled petri Net(CPN) is defined. The method of conflict resolution is discussed. There are manyoperating modes in the pumped-storage set, and the transitions between the modes are frequent and complex. So the controlledPetri Net is adopted to model and analyze the operating modes of the pumped-storage set. The programmable logic controller(PLC) is applied to implement the control of the opearting mode transitions.
