【摘要】：作為智能電網(wǎng)的重要環(huán)節(jié)之一,智能變電站的安全穩(wěn)定運(yùn)行對(duì)電網(wǎng)顯得格外重要,建設(shè)新一代智能變電站,提高變電站的保護(hù)控制運(yùn)行能力是電力系統(tǒng)發(fā)展的要求。新一代智能變電站采用頂層設(shè)計(jì)方案,并且要完成三個(gè)轉(zhuǎn)變,分專業(yè)設(shè)計(jì)向整體設(shè)計(jì)轉(zhuǎn)變、一次設(shè)備智能化向智能一次設(shè)備轉(zhuǎn)變、分散獨(dú)立系統(tǒng)向一體化業(yè)務(wù)系統(tǒng)轉(zhuǎn)變。本文對(duì)智能變電站的特征、系統(tǒng)結(jié)構(gòu)以及網(wǎng)絡(luò)結(jié)構(gòu)進(jìn)行了分析,總結(jié)出了新一代智能變電站相比于傳統(tǒng)變電站的優(yōu)缺點(diǎn),論文以此為基礎(chǔ)研究了新一代智能變電站保護(hù)控制的解決方案。隨著智能變電站的大范圍推廣,智能變電站大量采用光纜替代電纜連接,對(duì)于運(yùn)行檢修人員來說,二次回路變成了“黑匣子”,導(dǎo)致二次系統(tǒng)運(yùn)行維護(hù)復(fù)雜。因此,開展二次回路可視化、二次系統(tǒng)實(shí)時(shí)異常告警及智能診斷研究與應(yīng)用具有重要現(xiàn)實(shí)意義。本文在目前的SCD模型基礎(chǔ)上,對(duì)現(xiàn)有的二次系統(tǒng)信息模型進(jìn)行補(bǔ)充,補(bǔ)充一次設(shè)備模型、交換機(jī)模型,增加一、二次關(guān)聯(lián)信息建模,實(shí)現(xiàn)變電站一、二次模型及通信模型的關(guān)聯(lián),為二次系統(tǒng)可視化、異常告警等高級(jí)應(yīng)用奠定基礎(chǔ),并實(shí)現(xiàn)了基于擴(kuò)展SCD模型二次回路及壓板狀態(tài)的可視化。本文隨后又對(duì)一種二次系統(tǒng)移動(dòng)可視化運(yùn)維技術(shù)進(jìn)行了探討,該技術(shù)提高了變電站檢修、調(diào)試及擴(kuò)建的效率。伴隨著電網(wǎng)智能化、集約化的發(fā)展,保護(hù)設(shè)備下放就地,將成為重要的方向。為了從根本上解決二次回路不可視的問題,本文提出了一種新一代智能變電站現(xiàn)場(chǎng)級(jí)保護(hù)方案,該方案架構(gòu)簡(jiǎn)單,回路簡(jiǎn)潔,提高了保護(hù)的快速性和可靠性。本文對(duì)該現(xiàn)場(chǎng)級(jí)保護(hù)的研究背景及應(yīng)用的新技術(shù)進(jìn)行了闡述,并對(duì)不同方案進(jìn)行了探討,選出了最優(yōu)化的結(jié)構(gòu)方案。
[Abstract]:As one of the important links of smart grid, the safe and stable operation of intelligent substation is very important to the power grid. It is the requirement of the development of power system to construct a new generation intelligent substation and improve the protection and control ability of substation. The new generation intelligent substation adopts the top-level design scheme, and it is necessary to complete three transformations, from specialized design to overall design, from primary equipment intelligence to intelligent primary equipment, and from decentralized independent system to integrated business system. In this paper, the characteristics, system structure and network structure of intelligent substations are analyzed, and the advantages and disadvantages of the new generation intelligent substations compared with traditional substations are summarized. Based on this, the paper studies the solution of the new generation intelligent substation protection control. With the wide spread of intelligent substation, a large number of intelligent substations use optical cable instead of cable connection. For maintenance personnel, the secondary circuit has become a "black box", resulting in complex operation and maintenance of the secondary system. Therefore, the research and application of secondary loop visualization, real-time abnormal alarm and intelligent diagnosis of secondary system are of great practical significance. Based on the current SCD model, this paper complements the existing secondary system information model, complements the primary equipment model, the exchange model, adds the primary and secondary correlation information modeling, and realizes the substation first, the second time information modeling. The correlation between the quadratic model and the communication model lays the foundation for the secondary system visualization, abnormal warning and other advanced applications, and realizes the visualization of the secondary loop and the plate state based on the extended SCD model. In this paper, a mobile visual operation and maintenance technology for secondary system is discussed, which improves the efficiency of substation maintenance, commissioning and expansion. With the development of intelligent and intensive power network, the decentralized protection equipment will become an important direction. In order to solve the problem that the secondary circuit is invisible, this paper presents a new generation intelligent substation field level protection scheme. The scheme has the advantages of simple structure, simple circuit, and improves the rapidity and reliability of the protection. In this paper, the research background and new technology of the field level protection are described, and the different schemes are discussed, and the optimized structural scheme is selected.
