Research And Development On Simulation System Of 1000MW Ultra Super-critical Unit

With the enormous requirements for energy resource. especially for electric power energy in society, ultra-supercritical technology is developing continuously,1000MW ultra super-critical unit has been widely applied. Distributed Control System has been widely applied in the field of electric power industry with the rapid development of microcomputer technology, automation control technology, data communication technology and CRT technology. Simulation system is also developed rapidly to meet the demands of the design, debugging, detection, diagnosis and staff training. For the sake of establishing advanced automatic and informational platform for huge power plant and exerting advantage of simulation system sufficiently, full-scope simulation system of DCS is attracting more and more attention.This project is researched and developed based on SUPMAX800 distributed control system of Shanghai Automation Instrumentation Co..Ltd. The research aim is to turn the SUPMAX800 control system into its virtual mode and get virtual DPU simulation software with high fidelity and openness by using virtual DCS technology. And a simulation model is obtained by using modulization modeling idea and mechanism modeling idea based on choosing a 1000MW ultra super-critical unit of a power plant as a simulated object. Finally, a proper control scheme combining practical projects is designed, to control the 1000MW ultra super-critical unit based on distributed control system.The writer has mostly participated in the design and realization of the control method, logic and picture configuration, communication between model and control system, the startup commissioning of simulation system. The logic and picture configuration of turbine system, boiler system, air and flue system, feed-water system and HP heaters and LP heaters system are achieved by using SUPMAX800 based on practical engineering.Several parts are represented in this paper. In the first part, power plant simulation technology at home and abroad,ultra-supercritical technology and its simulation technology have been introduced, and a description for distributed control system, simulation mode and virtual DCS simulation technology have also been made. The second part is the main parts in this paper. Firstly, SUPMAX800 and its configuration software have been pointed out, furthermore, simulation model and its operation platform also have been introduced. And then, the full-scope simulation system including turbine master system, boiler master system and electrical system and the control scheme of all each subsystem have been introduced in detail. At last, the main task is to introduce the startup commissioning of simulation system, including systematic testing, realized functions of system, technical features and so on.With the popularity of the high performance simulation system, more and more power plants inclined to customize a simulation system just same as itself. And the simulation system will play a big role in the field of electric power industry, there is a wide development prospect even more.
