摘要
针对某火电厂辅网控制系统存在的运行年限长、故障频发、控制逻辑复杂、维护困难等问题,根据改造的技术要求及目的,从控制器及I/O测点配置及网络结构设计、接地系统改造、I/O测点排布、卡件布置等方面进行了优化。优化后降低了系统运行、检修、维护的难度,并将辅网控制系统纳入全厂信息管理系统,为实现主、辅网监视、运行、管理与控制一体化奠定了基础。
Aiming at the problems of long service life, frequent faults, complicated control logic and difficult maintenance of auxiliary network control system in a thermal power plant, according to the technical requirements and objectives of the transformation, this paper optimizes the configuration of controller and I/O measuring points, the design of network structure, the transformation of grounding system, the arrangement of I/O measuring points, and the arrangement of card parts, etc. Thus, the auxiliary network control system is brought into the information management system of the whole plant, which lays a foundation for the integration of master and auxiliary network monitoring, operation, management and control.
