摘要
目前国内水电站辅机控制的自动化程度普遍偏低且存在诸多问题。本文给出了一种基于现场总线全数字化技术的水电站辅机开关量和联锁保护的机电控制系统,实现了辅机控制的机电自动化。以先进的现场总线离散控制设备和柔性功能块组态方案为基础设计实现了被控系统中主要机电设备的开关量控制和保护策略,实现了在中央控制室对主要机电设备顺序控制的一键启停操作。构建了基于现场总线网络和以太网络的整体控制体系,在系统的现场级应用现场总线构建了控制子系统。系统改善了辅机系统运行的安全性和经济性,取得了较好的经济效益。
The automation level for the control of auxiliary equipment in old hydropower plants is very low and there are lots of existing problems.Electromechanical control system orienting discrete and inter-lock protection based on fieldbus technology is designed and developed for the control of auxiliary equipment in hydropower plants with advanced fieldbus technology to achieve full electromechanical automation in production.Based on advanced fieldbus discrete control devices and flexible function blocks configuration scheme,digital control and protection strategies for main electromechanical equipments in the controlled system are designed and implemented.Operation in control center with one-key operation for main electromechanical equipment was achieved.Control hierarchy based on fieldbus and Ethernet network is constructed.Automation,digitalization,networking and information in electromechanical control are fully implemented.The operation practice of the engineering project showed good control and economic performance index are achieved in production with the system,the security and economy in operation are improved greatly and significant economic benefit is achieved.
