摘　　要：为了优化火电厂管控信息系统,提出了基于时序Petri网的火电厂管控信息系统模型研究。首先提出了时序Petri网的分层建模方法,并给出了时序Petri网对复杂系统的建模步骤;其次,建立了整个火电厂管控信息系统的时序Petri网模型;再次,为了更好地分析和优化Petri网模型,对其进行了简化;最后,证明了简化后的时序Petri网大大减少了库所和变迁的数量并保持了原网的功能性。In order to optimize integration systems of management and control in power plant, study on model based on temporal Petri net is proposed. Firstly, modeling method of temporal Petri net is brought forward. And the modeling steps are given. Then, temporal Petri net model of the integration systems of management and control in power plant is set up. Thirdly, the Petri net is reduced for better analysis and optimization. In the end, the functionality of reduced Petri net is proved to be the same as original net and the number of places and transitions are reduced.
