Basic design stage is the most important design stage in automatic control system design. This design stage is mainly based on the contents determined in the preliminary design stage of the control system, and carries out the overall design of the system hardware and software. The functional specification is the main design document at the basic design stage, and it is the guiding document for the detailed design, software design and software debugging of the system. The main contents of the functional specification include design<In a power plant in Spain, ABB plans to integrate two redundant GE Mark V turbines with the whole plant process control. The Advant control system of ABB, a large DCS system in the plant, enables the turbine controller to be connected. The process port B and Miscro SCADA client software are used to display the process data transmitted from the turbine controller. ABB chose the integrated OPC to read and write 2096 process points in total for two turbines, 1098 points for each turbine.
Emilio Dominguez, the project manager of ABB, introduced OPC into the project. Apply Matrikon's products and consult Matrikon again about system solutions. At this time, Matrikon is developing an OPC Server for GE Mark V. Therefore, Matrikon and ABB have applied the second version of the beta version in Endesa Power Plant to realize and improve the server.
Emilio Dominguez said: "We chose Matrikon OPC because we have had a very pleasant cooperation experience with Matrikon and know that our two companies can cooperate to develop the best OPC for such comprehensive projects."
The project implementation process was very smooth, with the support of Matrikon OPC, helping to formulate the capital investment suitable for the plant equipment. The project proved to be very successful - now all the information of the turbine controller and other information of the factory are integrated into the large DCS system in the same data format.
"Matrikon's product and technical support were excellent from the beginning to the end of the project," Dominguez said. "With Matrikon's support, we completed the project in only two months“
ABB plans to apply this system in the Second Power Plant, and plans to integrate other turbine units in the next few years.
ABB is a leading manufacturer in the field of power and automation technology. ABB's technology can help power, public utilities and industrial customers improve their performance, while reducing the adverse impact on the environment. Petrochemical enterprises are an important part of achieving "energy conservation and emission reduction". Advanced control technology can ensure the early realization of this strategic goal. Several advanced control technologies are introduced in order to provide some help for the production of petrochemical enterprises. Keywords: petrochemical enterprises; Control technology; stable
Introduction As a process oriented chemical industry, the production process is basically carried out in the sealing device. As customers' requirements become more and more stringent, and competitors' level becomes higher and higher, how to maintain the stability in the process of production and make the number of unqualified products less and better becomes the top priority for producers. Large petrochemical enterprises must comprehensively apply automatic control technology, computer technology, information technology, network technology, etc., expand and speed up the construction of enterprise integrated automation system, improve the degree of information integration, improve the degree of management and control integration, so as to reduce raw materials and energy consumption, reduce costs, improve product output and quality, improve the overall efficiency of enterprises, and enhance competitiveness.
The development of petrochemical production control system The most important aspects of the development of petrochemical process control technology can be said to be the formation and development of cybernetics, the emergence and development of electronic computers, and the development of refining process (including equipment) technology itself. The classical (feedback) control theory formed in the 1940s is related to the PID control widely used in large-scale continuous production processes (including petrochemical processes); The "engineering cybernetics" that appeared in the 1950s is related to PID based cascade, feedforward, ratio, selectivity and other control technologies; These technologies are still used today. [1] In the late 1950s, modern control theory was formed in the process of space technology revolution. In the 1960s, people tried to apply modern control methods to petrochemical processes, but failed. The main reasons are: it is difficult to establish the mathematical model of the production process, and the control objectives and methods cannot be copied; Lack of technicians who understand both production process and control theory. In the early 1980s, the improvement of petrochemical process technology and equipment (including detection instruments and actuators), the progress of mathematical model research and development, the emergence of model predictive control (MPC) technology that inherits optimal control and adapts to production processes, the emergence of process control computer systems represented by DCS, the development of large system theory and artificial intelligence, and these technological advances, It has not only formed the advanced control [2] (APC) that began to be implemented in the petrochemical process in the 1980s, but also promoted the optimization of production devices and scheduling management, and developed towards the plant wide or company wide computer integrated system (CIMS). In recent years, the price of DCS has been declining, while the cost performance ratio has been improving. According to statistics, the price of DCS used in the control system of 34 control loops and 70 detection points is almost the same as that of electric type III instrument. The greater the number of loops, the better the economy.
