APS simulation system for 600MW supercritical unit based on virtual DCS stimulative simulator

Abstract

Large capacity supercritical unit automatic power plant startup and shutdown (APS) control technology has been a research hotspot in the field of plant automation. According to characteristics of general supercritical unit startup process, this paper introduces development process of supercritical unit APS stimulative simulation based on virtual DCS, including structure design, breakpoint design, interface configuration, development of functional groups and establishment of database, etc., which realizes auto startup process ranging from boiler ignition to full capacity, effectively improves production efficiency and makes significant reference value for practical application.
