摘要:

目前,生物燃气电厂项目的全厂控制系统多延用火电厂的一些规范及控制方式。火电厂在物料来源上相对稳定,而且对机组运行的控制要求非常苛刻,在控制系统的配置上是根据“不可停机”的理念而设计的。而对于生物燃气电厂,如果仍然沿用该方式来控制,就会造成不必要的浪费和不合理的控制。从生物燃气电厂的实际运行情况出发,提出了“分散控制,集中管理”的控制方式,该方式重点考虑了各单元环节的平衡耦合关系,可使系统达到最佳的运行状态,提高了发电效率。

Abstract:

At present, most biogas power stations follow the standards and control methods of thermal power plant for their plant control systems. The source of materials for thermal power plant is relatively stable, and the control requirements for units operation are quite strict. The configuration of the control system is designed according to the concept of “no stopping”. In the case of biogas power plant, if this method is continuously used to control, it will cause unnecessary waste and control irrationality. In this paper, according to the actual running situation of biogas power plant, it puts forward the control mode called “decentralized control, centralized management”. This mode takes the key consideration on balancing the coupling relationship between each unit in the procedure, which can optimize its running state and enhance the power generation efficiency.
