【摘要】：近些年來,國(guó)家正在大力支持電網(wǎng)朝智能化的方向進(jìn)行改革,并且進(jìn)行了巨大的投入�，F(xiàn)今,如何實(shí)現(xiàn)各種電力設(shè)備的智能化,與如何實(shí)現(xiàn)智能設(shè)備間的電力通信,發(fā)展智能電網(wǎng),都是主要的研究方向。智能電網(wǎng)具有許多重要的特征,如信息的智能化,互通化,采集和數(shù)據(jù)處理的自動(dòng)化等,其中信息化更是智能電網(wǎng)的首要特征。信息化的實(shí)現(xiàn)首先需要有一個(gè)全網(wǎng)統(tǒng)一的通信標(biāo)準(zhǔn),IEC61850這個(gè)新一代基于網(wǎng)絡(luò)通信的變電站自動(dòng)化系統(tǒng)國(guó)際標(biāo)準(zhǔn)應(yīng)運(yùn)而生。它的出現(xiàn)不僅解決了智能變電站中的“孤島”現(xiàn)象,而且實(shí)現(xiàn)了IED間的互換性和互操作性,從而使設(shè)備間的便利通訊成為了可能。所謂“互換性”是指,不同廠商生產(chǎn)的智能設(shè)備,在不改變系統(tǒng)內(nèi)的任一其他智能設(shè)備的情況下,不同廠商的智能設(shè)備可以隨意替換的能力。所謂“互操作性”是指,不管智能設(shè)備屬于或者不屬于同一個(gè)生產(chǎn)廠家,它們之間都能進(jìn)行信息交換,并根據(jù)信息進(jìn)行協(xié)同操作。如何開發(fā)智能設(shè)備,實(shí)現(xiàn)智能變電站的電力通信網(wǎng)絡(luò),是當(dāng)下研究的研究熱點(diǎn)和重點(diǎn)。而GOOSE作為IEC61850中的一個(gè)亮點(diǎn),在電力系統(tǒng)各領(lǐng)域的作用變得日益重要。GOOSE屬于GSE兩種報(bào)文結(jié)構(gòu)中的一種,它主要用于傳輸變電站中的跳閘、閉鎖等狀態(tài)量信息和開關(guān)信息。本文通過對(duì)IEC61850協(xié)議的研究與理解,對(duì)GOOSE的通信實(shí)現(xiàn)做了相應(yīng)的研究。本文首先對(duì)IEC61850和GOOSE的研究背景進(jìn)行了研究,并對(duì)國(guó)內(nèi)外的相關(guān)研究進(jìn)行了調(diào)研分析。接著,本文對(duì)IEC61850協(xié)議的主要結(jié)構(gòu)內(nèi)容以及GOOSE報(bào)文的幀格式和BER編碼規(guī)則進(jìn)行了介紹。同時(shí),結(jié)合IEC61850對(duì)如何實(shí)現(xiàn)GOOSE通信進(jìn)行了硬件及軟件方面的設(shè)計(jì)與研究。由于GOOSE在實(shí)時(shí)性和可靠性傳輸要求方面具有相當(dāng)高的要求,論文中設(shè)計(jì)采用Altera公司的現(xiàn)場(chǎng)可編程門陣列FPGA芯片EP4CE22E22I7N單CPU構(gòu)架模式。同時(shí),對(duì)如何運(yùn)用WinPcap搭建以太網(wǎng)實(shí)驗(yàn)環(huán)境做了相應(yīng)的介紹。最后,針對(duì)GOOSE報(bào)文本身的幾個(gè)性能和特征做了相關(guān)的實(shí)驗(yàn)研究。經(jīng)過測(cè)試實(shí)驗(yàn)表明,此套設(shè)備在滿足實(shí)時(shí)性和可靠性要求的同時(shí),能很好的完成對(duì)GOOSE報(bào)文的組幀和發(fā)送、接收和解析工作。
[Abstract]:In recent years, the state is vigorously supporting the reform of the power grid in the direction of intelligence, and has made a huge investment. Nowadays, how to realize the intelligence of all kinds of power equipment, how to realize the electric power communication between the intelligent devices, and how to develop the smart grid are the main research directions. Smart grid has many important features, such as intelligence of information, intercommunication, automation of data acquisition and data processing, and information is the most important feature of smart grid. The realization of informatization requires a unified communication standard of the whole network, IEC61850, which is a new international standard of substation automation system based on network communication. It not only solves the "isolated island" phenomenon in intelligent substation, but also realizes the interchangeability and interoperability between IED, which makes the convenient communication between devices possible. The so-called "interchangeability" refers to the ability of different manufacturers to replace intelligent devices without changing any other intelligent devices in the system. The so-called "interoperability" means that intelligent devices, whether they belong to the same manufacturer or not, can exchange information and cooperate with each other according to the information. How to develop intelligent equipment and realize the electric power communication network of intelligent substation is the research focus. As a bright spot in IEC61850, GOOSE plays an increasingly important role in various fields of power system. Goose belongs to one of the two GSE message structures. It is mainly used to transmit state information and switch information such as tripping and latching in substation. Based on the research and understanding of IEC61850 protocol, the communication implementation of GOOSE is studied in this paper. Firstly, the research background of IEC61850 and GOOSE is studied, and the related research at home and abroad is analyzed. Then, the main structure of IEC61850 protocol, frame format of GOOSE packet and BER coding rules are introduced. At the same time, the hardware and software design and research on how to realize GOOSE communication are carried out based on IEC61850. Due to the high requirement of real-time and reliability transmission of GOOSE, the EP4CE22E22I7N single CPU architecture mode of FPGA chip of Altera company is adopted in this paper. At the same time, how to use WinPcap to build ethernet experimental environment is introduced. Finally, the performance and characteristics of GOOSE packets are studied. The test results show that the device can meet the requirements of real-time and reliability, and at the same time, it can complete the framing, sending, receiving and parsing of GOOSE packets.
