控制系統(tǒng)基本設計階段
基本設計階段是自動控制系統(tǒng)設計中為重要的設計階段。該設計階段主要以控制系統(tǒng)初步設計階段確定的內(nèi)容為基礎, 對系統(tǒng)硬件和軟件進行總體方面的設計。功能規(guī)格書是基本設計階段主要的設計文件,它是系統(tǒng)詳細設計、軟件設計和軟件調(diào)試工作的指導性文件。功能規(guī)格書的主要內(nèi)容包括設計<在西班牙某電廠，ABB計劃讓兩臺冗余的GE Mark V渦輪機與全廠過程控制進行集成。實現(xiàn)渦輪控制器接入工廠的大型DCS系統(tǒng)－－-ABB的Advant控制系統(tǒng)。過程端口B和Miscro SCADA客戶端軟件用來顯示從渦輪控制器傳送的過程數(shù)據(jù)。ABB公司選擇了一體化的OPC來讀寫兩個渦輪總共2096個過程點，每個渦輪1098個點。
ABB的項目經(jīng)理埃米利奧多明格斯在項目中引入了OPC。應用Matrikon的產(chǎn)品，并且再次就系統(tǒng)解決方案咨詢Matrikon公司。此時Matrikon公司正在發(fā)展一款OPC Server for GE Mark V，由此Matrikon 和ABB公司在Endesa電廠應用了測試版的第二版來實現(xiàn)和改善服務器。
埃米利奧多明格斯說：“我們選擇Matrikon OPC是因為和Matrikon公司有過非常愉快的合作經(jīng)歷，并且知道我們兩家公司可以就此類綜合項目合作開發(fā)出好的OPC。”
項目實施過程非常順利，Matrikon OPC支持，協(xié)助制定適合工廠設備的資金投入。項目被證明非常成功———現(xiàn)在渦輪控制器所有的信息和工廠其他的信息以一樣的數(shù)據(jù)格式被整合到大型DCS系統(tǒng)中。
“從項目的開始到結束Matrikon的產(chǎn)品和技術支持” 多明格斯說：“在Matrikon的支持下，我們僅用了兩個月的時間就完成了該項目“
ABB公司計劃在第二家電廠應用此套系統(tǒng)，并且計劃在未來幾年內(nèi)整合其他的渦輪機組。

1 石化生產(chǎn)控制系統(tǒng)的發(fā)展過程石油化工過程控制技術的發(fā)展主要的可以說是控制論的形成和發(fā)展、電子計算機的出現(xiàn)和發(fā)展、以及煉油工藝（包括裝備）技術本身的發(fā)展。 40年代形成的經(jīng)典（反饋）控制論，與大規(guī)模連續(xù)生產(chǎn)過程（包括石油化工過程）中廣泛采用的PID控制相聯(lián)系；50年代出現(xiàn)的“工程控制論”與基于PID的串級、前饋、比值、選擇性等控制技術相聯(lián)系；這些技術一直沿用至今。[1] 50年代末，在航天技術革命過程中，形成了現(xiàn)代控制理論，到60年代，人們試圖將現(xiàn)代控制方法應用到石油化工過程，但未取得成功。其主要原因是：建立生產(chǎn)過程數(shù)學模型較困難，控制的目標和方法不能照搬；缺少既懂生產(chǎn)工藝又懂控制理論的技術人員。 80年代初，石油化工過程工藝及裝備（包括檢測儀表和執(zhí)行機構）的改進、數(shù)學模型研究與開發(fā)的進展、繼承了優(yōu)控制又適應生產(chǎn)過程的模型預估控制（MPC）技術的出現(xiàn)，以DCS為代表的過程控制計算機系統(tǒng)的出現(xiàn)、大系統(tǒng)理論和人工智能的發(fā)展，這些技術進步，不僅形成了80年代在石油化工過程中開始付諸實現(xiàn)的先進控制[2]（APC），也推動了生產(chǎn)裝置優(yōu)化、調(diào)度管理優(yōu)化，朝著全廠或全公司計算機集成系統(tǒng)（CIMS）發(fā)展。近年來，DCS的價格不斷下降，而性價比卻不斷提高。據(jù)統(tǒng)計，34個控制回路、70個檢測點的控制系統(tǒng)采用DCS的價格已與電III型儀表幾乎相當?；芈窋?shù)越增加，其經(jīng)濟性則越好。Basic design stage of control system
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.
