【摘要】：隨著目前我國(guó)經(jīng)濟(jì)大力發(fā)展，人民生活和工業(yè)生產(chǎn)對(duì)供電需求和供電可靠性的要求逐漸增加，給供電系統(tǒng)帶來(lái)了新的挑戰(zhàn)和機(jī)遇。21世紀(jì)以來(lái)，大功率電子技術(shù)、網(wǎng)絡(luò)通信技術(shù)的日趨成熟，使智能電網(wǎng)從最初的概念逐漸成為現(xiàn)實(shí)，這讓智能電網(wǎng)的可靠、安全、經(jīng)濟(jì)、高效、環(huán)境友好和使用安全的目標(biāo)不再是夢(mèng)想，而做好伴隨著智能電網(wǎng)而出現(xiàn)的智能變電站的設(shè)計(jì)與建設(shè)工作，就顯得尤為重要。 智能變電站是智能電網(wǎng)的可靠支撐，是承擔(dān)輸配電的樞紐，智能變電站的可靠與否直接決定了智能電網(wǎng)設(shè)備的監(jiān)控與運(yùn)行操作能力，同時(shí)為調(diào)控一體化及運(yùn)維檢修提供技術(shù)支持。本文主要針對(duì)長(zhǎng)沙地區(qū)洞陽(yáng)鎮(zhèn)經(jīng)濟(jì)發(fā)展迅速、電力負(fù)荷增大導(dǎo)致的電力系統(tǒng)容量不足的情況，對(duì)洞陽(yáng)鎮(zhèn)110kV變電站及其智能化進(jìn)行了設(shè)計(jì)。 本文在對(duì)智能化一次設(shè)備相關(guān)的先進(jìn)技術(shù)及設(shè)備進(jìn)行闡述的基礎(chǔ)上，對(duì)智能變壓器、高壓開關(guān)設(shè)備及電子式互感器以及二次設(shè)備與其關(guān)鍵技術(shù)進(jìn)行了深入的原理分析，包括IEC61850通訊規(guī)約，通信和網(wǎng)絡(luò)技術(shù)、對(duì)時(shí)及同步技術(shù)等。智能變電站與常規(guī)變電站的主要差異就在于一、二次設(shè)備之間通過(guò)全站信息共享進(jìn)行一體化管理，從而使智能變電站達(dá)到信息化、自動(dòng)化和互動(dòng)化。 最后，根據(jù)前文的分析，依據(jù)智能變電站的設(shè)計(jì)框架，，針對(duì)長(zhǎng)沙地區(qū)洞陽(yáng)鎮(zhèn)110kV智能變電站進(jìn)行了設(shè)計(jì)。從多個(gè)方面，如一次設(shè)備的智能化、信息的標(biāo)準(zhǔn)化、信息共享的網(wǎng)絡(luò)化、應(yīng)用功能的智能化、與主站及用戶的互動(dòng)化以及輔助應(yīng)用的智能化等，對(duì)智能變電站的設(shè)計(jì)進(jìn)行了全面的分析與探討。并在文章最后對(duì)變電站的實(shí)際運(yùn)行情況進(jìn)行了評(píng)估、對(duì)運(yùn)行過(guò)程中產(chǎn)生的問題提出了相應(yīng)的解決方案。
[Abstract]:With the development of our country's economy, the demand for power supply and the reliability of power supply are gradually increasing in the people's life and industrial production, which brings new challenges and opportunities to the power supply system. Since the 21st century, the high-power electronic technology has been applied to the power supply system. With the maturity of network communication technology, the smart grid has gradually become a reality from the original concept, which makes the goal of the smart grid reliable, safe, economical, efficient, environmentally friendly and safe to use is no longer a dream. It is very important to design and construct smart substation with smart grid. Intelligent substation is the reliable support of smart grid and the hub of transmission and distribution. The reliability of intelligent substation directly determines the monitoring and operation ability of smart grid equipment. At the same time, it provides technical support for the integration of regulation and control and maintenance and repair. This paper mainly aims at the situation that the economic development of Dongyang Town in Changsha area is rapid, and the power system capacity is insufficient due to the increase of power load. The 110 kV substation in Dongyang Town and its intelligent design are designed. On the basis of expounding the advanced technology and equipment related to intelligent primary equipment, this paper analyzes the principle of intelligent transformer, high-voltage switchgear, electronic transformer, secondary equipment and its key technology. Including IEC61850 communication protocol, communication and network technology, timing and synchronization technology, etc. The main difference between intelligent substation and conventional substation lies in the integrated management between primary and secondary equipments through the information sharing of the whole station. So that intelligent substation to achieve information, automation and interaction. Finally, according to the above analysis, according to the design frame of intelligent substation, the 110kV intelligent substation of Dongyang Town in Changsha area is designed. The network of information sharing, the intelligence of application function, the interaction with master station and user, and the intelligence of auxiliary application, etc. The design of intelligent substation is comprehensively analyzed and discussed. At the end of the paper, the actual operation of substation is evaluated, and the corresponding solutions to the problems in operation are put forward.
