【摘要】：目前，智能變電站在我國發(fā)展迅速，特別是其主要電氣設(shè)備的智能化設(shè)計與建設(shè)日趨完善。但智能變電站的內(nèi)涵不僅限于主要的電氣設(shè)備，更需要站內(nèi)大量的輔助設(shè)備也參與進來，實現(xiàn)輔助系統(tǒng)的集成化、智能化，如水泵、風(fēng)機、空調(diào)等設(shè)備，從而提升設(shè)備綜合管理，輔助監(jiān)測設(shè)備的運行狀態(tài)，可靠傳遞相關(guān)故障信息，最終實現(xiàn)變電站的安全生產(chǎn)能力的進一步提高。智能輔助控制系統(tǒng)是電網(wǎng)智能化和安全生產(chǎn)的重要支撐技術(shù)之一，它將通風(fēng) 系統(tǒng)、水系統(tǒng)、火災(zāi)報警、視頻、安防、環(huán)境監(jiān)控以及設(shè)備控制等各大系統(tǒng)有機集成，并實現(xiàn)聯(lián)網(wǎng)監(jiān)控和管理。當前的智能輔助系統(tǒng)包括三部分：圖像監(jiān)視及安全警衛(wèi)子系統(tǒng)、環(huán)境監(jiān)控子系統(tǒng)和火災(zāi)報警子系統(tǒng)，由于專業(yè)管理的特殊性，變電站消防系統(tǒng)，特別是水消防系統(tǒng)和通風(fēng)消防系統(tǒng)等一直游離在智能輔助系統(tǒng)以外，尤其是消防蓄水、給水系統(tǒng)，在連鎖控制、信息存儲和上傳、巡檢維護、故障分析等方面只能就地采集。本研究是根據(jù)現(xiàn)有智能變電站建設(shè)要求，將變電站消防控制系統(tǒng)與智能輔助控制系統(tǒng)優(yōu)化整合，使得智能輔助系統(tǒng)更加完善和充分，從而將所有相關(guān)因素在產(chǎn)品設(shè)計階段得到綜合規(guī)劃和優(yōu)化。通過依托九園110kV變電站工程對變電站的消防控制系統(tǒng)與智能輔助控制系統(tǒng)的整合進行研究，提出了完善智能輔助控制系統(tǒng)的站內(nèi)覆蓋范圍的方法，實現(xiàn)了消防系統(tǒng)的監(jiān)控運行效率和可靠性的提高。在充分利用基于DL/T860協(xié)議 的高速以太網(wǎng)的平臺條件基礎(chǔ)上，智能輔助控制系統(tǒng)構(gòu)架中后臺與各子系統(tǒng)間可實現(xiàn)實時通信，，同時改造融合原消防控制系統(tǒng)，使其具備與綜合應(yīng)用服務(wù)器通訊的功能，充分利用現(xiàn)有智能輔助控制系統(tǒng)中視頻顯示、圖像存儲回放、報警、監(jiān)視控制、聯(lián)動控制等功能，使得智能輔助控制系統(tǒng)的監(jiān)控范圍進一步擴大、效率進一步提高。
[Abstract]:At present, intelligent substation is developing rapidly in our country, especially the intelligent design and construction of its main electrical equipment is becoming more and more perfect. But the connotation of intelligent substation is not only limited to the main electrical equipment, but also needs a large number of auxiliary equipment in the station to participate in, to realize the integration of auxiliary system, intelligent, such as water pump, fan, air conditioning and so on. Thus the comprehensive management of the equipment can be improved, the operation state of the equipment can be monitored, and the relevant fault information can be transmitted reliably. Finally, the safe production capacity of the substation will be further improved. Intelligent auxiliary control system is one of the important supporting technologies for intelligent and safe production of power grid. It integrates ventilation system, water system, fire alarm, video, security, environment monitoring and equipment control, etc. And the implementation of network monitoring and management. The current intelligent assistant system consists of three parts: image monitoring and security subsystem, environment monitoring subsystem and fire alarm subsystem. Due to the particularity of professional management, substation fire protection system, Especially the water fire control system and the ventilation fire fighting system have been free outside the intelligent auxiliary system, especially in the fire control, water supply system, chain control, information storage and upload, inspection and maintenance, fault analysis and other aspects can only be collected on the spot. According to the requirement of intelligent substation construction, this study optimizes and integrates the fire control system of substation and the intelligent auxiliary control system, which makes the intelligent auxiliary system more perfect and sufficient. Therefore, all relevant factors are comprehensively planned and optimized in the product design stage. Based on Jiuyuan 110kV substation project, the integration of fire control system and intelligent auxiliary control system of substation is studied, and the method of perfecting the coverage of intelligent auxiliary control system is put forward. The efficiency and reliability of fire control system are improved. On the basis of making full use of the platform condition of high speed Ethernet based on DL/T860 protocol, real-time communication can be realized between the background and subsystems in the framework of intelligent auxiliary control system, and the original fire control system can be recombined at the same time. It has the function of communicating with the integrated application server, and makes full use of the functions of video display, image storage and playback, alarm, monitoring and control, linkage control and so on in the existing intelligent auxiliary control system. The monitoring range of the intelligent auxiliary control system is further expanded and the efficiency is further improved.
