摘要针对企业的生产和能源调度需求,采用模块化方法建立并研究了连续型企业生产一能耗耦合式动态调度系统的微分Petri网(DPN)模型,以解决当前能源调度与生产调度脱节的问题。该模型由总体架构模型、带遥调或遥信阀门的系统传输管网模型、检测预警模型、带协同约束弧的调度预警器模型和备用设备模型组成。采用DPN仿真算法,通过调整遥调、遥控和遥信阀门实现了系统DPN模型的动态调度仿真。该生产与能耗耦合的动态调度系统的软件已实现了从工艺界面到调度界面的转化。该系统对企业生产和能源管理具有重要的辅助作用。
Aiming at enterprises' needs for production and energy dispatching, a differential Petri net (DPN) model for a dynamic dispatching system based on production-energy consumption coupling for continuous process enterprises was established using the module method, and was studied to solve the present problem of the divorce between pro- duction dispatching and energy consumption dispatching. The model consists of the overall framework model, the transmission pipeline network model with an teleadjusting or telecommand valve gate, the detection and warning model, the dispatching warning model with an cooperation inhibiting arc and the standby equipment model. Using the simulation algorithm of DPN, the dynamic dispatching simulation of the system DPN model was realized by adjusting teleadjusting, telecommand or telesignalization valve gates. The software of the production-energy consumption coupling dynamic system was implemented, especially the transformation from the process planning interface to the dynamic dispatching interface. This system is of great assistance in managing production and energy in continuous process enterprises.
