【摘要】：隨著我國經(jīng)濟(jì)和社會的快速發(fā)展,人們的節(jié)能和環(huán)保意識不斷地增強(qiáng),節(jié)約能源、保護(hù)環(huán)境成為了越來越重要的問題。而冬季供熱作為環(huán)境污染和能源消耗的集合體成為了人們越來越關(guān)注的問題。如何人性化地控制供熱系統(tǒng),使其運(yùn)行在高效節(jié)能的狀態(tài)下,已經(jīng)成為了現(xiàn)階段供熱系統(tǒng)研究的主要問題。 本文以青島某高校的集中供熱節(jié)能調(diào)度監(jiān)控系統(tǒng)項目為背景,介紹了集中供熱系統(tǒng)的結(jié)構(gòu)和原理,重點(diǎn)研究了集中供熱系統(tǒng)中的換熱站控制策略和控制算法,設(shè)計了青島某高校集中供熱節(jié)能調(diào)度監(jiān)控系統(tǒng)。 本文中具體工作如下：首先介紹了集中供熱系統(tǒng)中換熱站的結(jié)構(gòu)、原理及其控制原理與要求,然后分析換熱站節(jié)能調(diào)節(jié)措施,在以往換熱站溫度控制策略的基礎(chǔ)上提出了新的換熱站溫度控制策略；同樣在以往換熱站的控制算法的基礎(chǔ)上,提出了本文換熱站的控制算法——模糊Smith控制；最后根據(jù)青島某高校集中供熱系統(tǒng)的具體情況,以西門子S7-200PLC為控制器,設(shè)計了青島某高校集中供熱控制系統(tǒng),以工業(yè)組態(tài)軟件——紫金橋組態(tài)軟件為工具,設(shè)計了青島某高校集中供熱監(jiān)控系統(tǒng),從而實現(xiàn)了青島某高校集中供熱節(jié)能調(diào)度監(jiān)控系統(tǒng)的設(shè)計。 根據(jù)以上集中供熱節(jié)能調(diào)度監(jiān)控系統(tǒng)的設(shè)計,實現(xiàn)了集中供熱系統(tǒng)的遠(yuǎn)程監(jiān)控,根據(jù)用戶的不同用熱需求分時分區(qū)控制,既保證了用戶的用熱需求,又保證能源的有效利用,從而達(dá)到按需供熱,節(jié)約能源的目的。 目前,青島某高校集中供熱節(jié)能調(diào)度監(jiān)控系統(tǒng)已經(jīng)調(diào)試成功,且系統(tǒng)運(yùn)行穩(wěn)定,基本達(dá)到系統(tǒng)的設(shè)計目的。
[Abstract]:With the rapid development of our country's economy and society, people's consciousness of energy saving and environmental protection is becoming more and more important. As a combination of environmental pollution and energy consumption, heating in winter becomes more and more concerned. How to humanize the control of heating system and make it run in the state of high efficiency and energy saving has become the main problem in the current research of heating system. In this paper, the structure and principle of central heating system are introduced, and the control strategy and control algorithm of heat exchange station in central heating system are mainly studied under the background of the project of centralized heating energy saving dispatching monitoring system in a university in Qingdao, and the structure and principle of central heating system are introduced in this paper. In this paper, a monitoring and control system for energy saving of central heating in a university in Qingdao is designed. The specific work in this paper is as follows: firstly, the structure, principle, control principle and requirements of the heat exchange station in the central heating system are introduced, and then the energy saving regulation measures of the heat exchange station are analyzed. Based on the former control strategy of heat transfer station temperature, a new control strategy of heat transfer station temperature is put forward, and the fuzzy Smith control algorithm of the heat exchange station is put forward on the basis of the control algorithm of the former heat exchange station. Finally, according to the concrete situation of the central heating system of a university in Qingdao, taking Siemens S7-200 PLC as the controller, the centralized heating control system of a university in Qingdao is designed. The industrial configuration software-Zijingqiao configuration software is used as the tool. This paper designs a centralized heating monitoring system for a university in Qingdao, thus realizing the design of a centralized heating energy saving dispatching monitoring system in a university in Qingdao. According to the above design of the centralized heating energy saving dispatching monitoring system, the remote monitoring of the central heating system is realized. According to the users' different heat demand, the time-sharing and partition control can not only guarantee the users' heat demand, but also ensure the effective use of energy. In order to achieve the purpose of heating on demand and saving energy. At present, the monitoring and control system for central heating and energy saving in a university in Qingdao has been successfully debugged, and the system is running stably, which basically achieves the purpose of system design.
