【摘要】：近些年来,国家正在大力支持电网朝智能化的方向进行改革,并且进行了巨大的投入。现今,如何实现各种电力设备的智能化,与如何实现智能设备间的电力通信,发展智能电网,都是主要的研究方向。智能电网具有许多重要的特征,如信息的智能化,互通化,采集和数据处理的自动化等,其中信息化更是智能电网的首要特征。信息化的实现首先需要有一个全网统一的通信标准,IEC61850这个新一代基于网络通信的变电站自动化系统国际标准应运而生。它的出现不仅解决了智能变电站中的“孤岛”现象,而且实现了IED间的互换性和互操作性,从而使设备间的便利通讯成为了可能。所谓“互换性”是指,不同厂商生产的智能设备,在不改变系统内的任一其他智能设备的情况下,不同厂商的智能设备可以随意替换的能力。所谓“互操作性”是指,不管智能设备属于或者不属于同一个生产厂家,它们之间都能进行信息交换,并根据信息进行协同操作。如何开发智能设备,实现智能变电站的电力通信网络,是当下研究的研究热点和重点。而GOOSE作为IEC61850中的一个亮点,在电力系统各领域的作用变得日益重要。GOOSE属于GSE两种报文结构中的一种,它主要用于传输变电站中的跳闸、闭锁等状态量信息和开关信息。本文通过对IEC61850协议的研究与理解,对GOOSE的通信实现做了相应的研究。本文首先对IEC61850和GOOSE的研究背景进行了研究,并对国内外的相关研究进行了调研分析。接着,本文对IEC61850协议的主要结构内容以及GOOSE报文的帧格式和BER编码规则进行了介绍。同时,结合IEC61850对如何实现GOOSE通信进行了硬件及软件方面的设计与研究。由于GOOSE在实时性和可靠性传输要求方面具有相当高的要求,论文中设计采用Altera公司的现场可编程门阵列FPGA芯片EP4CE22E22I7N单CPU构架模式。同时,对如何运用WinPcap搭建以太网实验环境做了相应的介绍。最后,针对GOOSE报文本身的几个性能和特征做了相关的实验研究。经过测试实验表明,此套设备在满足实时性和可靠性要求的同时,能很好的完成对GOOSE报文的组帧和发送、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.
