The optimization technology and application of the coordinated control system of 1000MW ultra supercritical power units passed the appraisal

on March 19, 2013, organized by the Department of science and technology of Guangdong Province, Guangdong power company hosted a meeting in Guangzhou on the Power Research Institute of Guangdong power company, China Resources power (Hezhou) Co., Ltd "1000MW ultra supercritical power generation with dual inlet and dual outlet coal mills" undertaken by Guangdong Shaoguan Yuejiang Power Generation Co., Ltd. on March 19, 2013, organized by the Department of science and technology of Guangdong Province, Guangdong power company hosted a meeting in Guangzhou for the Electric Power Research Institute of Guangdong power company, China Resources power (Hezhou) Co., Ltd. and Guangdong Shaoguan Yuejiang Power Generation Co., Ltd "The economic strength of 1000MW Ultra Supercritical generator set equipped with double inlet and double outlet pulverizers is not in line with that of most regions in China. Relying on the advantages of deep cultivation of the industry for many years, 7. Optimization technology and application of oil pump plunger corrosion coordination control system" achievement appraisal meeting, the appraisal committee listened to the work report, technical report, test report, application certificate and domestic and foreign novelty search report of the project, and after careful deliberation, The appraisal opinions of the scientific and technological achievements are as follows:

1. The technical documents provided for appraisal are complete and standardized, which meet the requirements of scientific and technological achievements appraisal

2. For the first time, a mathematical model of the dynamic characteristics of the material level and the amount of coal into the furnace of the double inlet and double outlet coal pulverizer for almost all body parts of the polar 1 automobile used in the design of the control system is established, and a soft sensing technology for the amount of coal into the furnace of the double inlet and double outlet coal pulverizer under all working conditions is proposed, which significantly improves the quality of the coordinated control of combustion and combustion of the unit

3. Based on the relative gain theory, a control system structure that conforms to the actual process of the double inlet and double outlet pulverizing system is established, and the multivariable fine control of the pulverizer is realized

4. A cascade control system anti integral saturation method based on the linkage of process system is proposed, which widens the controllable range of the capacity damper of the double inlet and double outlet coal pulverizing system

this achievement has originality and independent intellectual property rights, and the overall technology is at the international advanced level. The appraisal committee unanimously agreed to pass the appraisal of this achievement and recommended its popularization and application
