摘要
随着发电厂大型机组的应用,对发电厂控制系统的要求也越来越高,但是独立的子系统并不能满足控制要求。本文主要立足于如何解决大型火电厂辅网集中控制系统的问题,主要介绍了现场总线在大型火电厂辅网集中控制系统的运用、火电厂中锅炉恒压供水常见的系统设计案例,以及概述了辅网子系统间通讯抗干扰问题的常见解决方法。
with the power of large unit application, the requirement of power plant control system is becoming more and more high, but independent subsystems and cant meet the control requirements. In this paper, based on how to solve the problem of large power plant auxiliary network central control system, mainly introduced the field bus in the large use of auxiliary network central control system in thermal power plants, the common of constant pressure water supply system in the coal-fired power plant boiler design case, and summarizes the auxiliary network system anti-jamming communication between common solution of the problem.
