Integrated control system of cement clinker, waste heat power generation and steam turbine safety protection

Abstract

The invention provides an integrated control system of cement clinker, waste heat power generation and steam turbine safety protection, in particular a plant control system that integrates cement clinker DCS, waste heat power generation DCS and steam turbine safety protection DEH and ETS. The invention is characterized in that the integrated control operating system with a same database, a same data industrial Ethernet, same DCS / PLC software, same software compatible DCS / PLC hardware and a same human-computer interface realizes local operation and overall monitoring of the whole plant through data sharing and network sharing so that production and equipment operate safely and efficiently so as to reduce the fixed number of workers and the labor intensity.

Description

technical field [0001] The invention relates to an integrated safety protection control system for a cement plant, in particular to an integrated control system that integrates cement clinker DCS, waste heat power generation DCS, and steam turbine control and protection DEH. Background technique [0002] At present, due to capital and technical problems in domestic cement plants, most of the cement clinker line and waste heat power generation production line are not constructed at the same time. They are not of the same brand, even if they are of the same brand, they are two completely independent systems. In addition, steam turbine DEH (electro-hydraulic regulating system) and ETS (emergency trip system) have higher professional technical requirements, and are currently completed by boiler supporting manufacturers, and they are completely independent island systems with waste heat power generation DCS. At present, due to the more detailed division of labor in foreign count...

Problems solved by technology

[0005] In order to overcome the shortcomings of the existing clinker cement line DCS, waste heat power generation DCS, steam turbine protection and control DEH, and ETS, the three independent systems do not share data, the man-machine interface is not unified, and the control is not interlocked. The factory has the same database, the same industrial Ethernet, the same DCS / PLC software, the same software is compatible with DCS / PLC hardware, and the integrated control system of the same man-machine interface, namely the clinker cement line DCS, waste heat power generation DCS, steam turbine protection control DEH, ETS is a different control station of the same system. It queries data, judges faults, and analyzes problems through an overall database. It realizes data exchange, control interlocking, and blind spot display through an industrial Ethernet, and realizes coordinated operation through the same human-machine interface to ensure the process The realization of strategies and production management ensures the safe, long-term and stable operation of equipment. In addition, through unified planning and step-by-step implementation, construction costs are reduced, labor quotas are reduced, and labor intensity is reduced.
