This project belongs to the technical field of process automatic control and testing of power generation equipment in the field of industrial automation control.
Industrial electricity cannot be stored, and the production process must be continuous to ensure the safe and economical operation of the generating set. As an enterprise-owned power plant, the stability of power generation is directly related to the power safety of East China Power Grid and society. It also plays a decisive role in reducing steel manufacturing costs and maintaining production safety in the casting process. Moreover, thermal power plants and steel companies are both highly polluting industries in the traditional sense. The stability of power generation is also related to the normal investment of environmental protection equipment and whether air pollutant emissions meet environmental protection indicators.
Taking the 350MW power plant as an example, the main line equipment is automatically controlled, and the number of detection and driving equipment is configured to be nearly 10,000. Only by coordination and cooperation during this period can unplanned power interruption accidents be avoided. Traditional power generation calibration technology has the following problems in the production process: after an equipment failure occurs, load reduction or even shutdown can be eliminated; equipment in some areas does not yet have the conditions for quantitative data calibration, and qualitative judgment cannot be made in a timely manner by relying on people's five senses. Realistically control the equipment condition.
The digital calibration technology of power generation equipment is innovative in the equipment fault handling process and how to avoid the risk of unit load reduction or even shutdown, and updates a number of equipment maintenance concepts.
The main technological innovations include:
1:"Breaking the rules", innovative technology opens up a new equipment maintenance method in the field of industrial automation control that is unprecedented in the industry.
For equipment that requires load reduction or even shutdown during the treatment process after high temperature, rain, vibration, and corrosion faults, we have independently developed a number of calibration devices, which are cleverly combined with the calibration method to achieve a new maintenance method of troubleshooting without reducing power generation.
2:"From scratch", innovate technology to improve inspection blind spots, and establish a data platform to realize the transformation from diagnosis and prevention of equipment faults, qualitative to quantitative.
Develop equipment process background simulation devices to create calibration possibilities. The digital platform displays multi-dimensional characteristic parameters and provides fast, accurate and unique data to support fault diagnosis and prevention.
3:"People-oriented", innovative technologies independently develop digital security early warning devices to provide employees with a safe inspection environment based on practical work.
In industrial manufacturing, human safety is the top priority. Starting from practical problems such as avoiding maintenance personnel from being exposed to high temperature radiation and blows, calibration and safety alarm devices have been developed to transfer workplaces in harsh environments, and safety warnings control personal safety.
4:"Recycling", innovative technology provides a way to recycle equipment after repair, saving manufacturing resources.
Intermediate media is used to obtain tiny mechanical variables, which are then amplified and converted into visual digital quantities to provide repair judgment, so that high value-added components can be recycled on the machine.
Since its application in 2013, as of 2015, innovative technologies have been used to shorten the power generation benefits of increased failure time and reduce the power generation costs of recycling restoration and utilization, resulting in a total of 80.355 million yuan in new profits in the past three years; a total of 15 patents have been generated, including 7 of the 11 invention patents have been authorized; 10 corporate technical secrets have been identified; and one paper has been published in a national core journal.
Innovative technologies have been recognized and evaluated by many well-known companies in the field of automatic control at home and abroad. The calibration technology has passed the metrology test data of Beijing Iron and Steel Design Institute and Baosteel Co., Ltd., and can be applied to automated equipment data analysis. Integrated technology has been promoted and applied in Baosteel Power Plant, Baosteel Industrial Technology Service Co., Ltd., Zhanjiang Iron and Steel, Xinjiang Hami Xuanli Gas Power Plant and other units. The calibration and maintenance involved in innovative technologies have formed a number of specifications in Baosteel Power Plant, Zhanjiang Iron and Steel Equipment Department, and Zhanjiang Iron and Steel Energy and Environmental Protection Department.
Digital calibration technology for power generation equipment integrates multiple patents to ensure the stability of power generation equipment, greatly promotes technological progress in the field of power generation equipment calibration and maintenance, and has achieved significant economic and social benefits. It has been widely promoted and applied in the field of automation control. space.
