【摘要】：基于IEC 61850标准建设的智能变电站增加了过程层网络及设备,过程层设备信息的网络化传输使过程层设备上传信息和交互信息大幅增加,使客户端可以更准确地掌握二次设备工作状态。但是,目前我国已建成的智能变电站对信息的利用技术仍然停留在综合自动化变电站的水平。在监控后台、网络报文分析仪等有必要开发信息智能化运用的设备上,都采用了信息捕获、提取、显示的方法。这种单一的信息提取后展示信息条方式,没有体现智能变电站实现智能变电站中信息分析智能化的目标,浪费了宝贵的信息资源。为了充分利用智能变电站通信网络上传输的所有报文信息,设计了智能变电站在线信息综合应用系统。本文介绍了该系统核心功能实现需要的功能组件和测试组件。功能组件本文介绍了图形化展示组件和GOOSE/SV(面向通用对象的变电站事件/采样值)解析组件。测试组件本文介绍了过程层通信测试组件和用于站控层通信测试的MMS客户端、服务器。本文所做的主要工作是:1、研究智能变电站二次系统,主要包括二次系统的通信网络结构、设备间的通讯方式、设备的ACSI信息模型。2、研究智能变电站继电保护功能图形化展示的方法。重点介绍了Sugiyama算法。基于Sugiyama算法实现了在线信息综合应用系统图形展示化组件。3、研究IEC 61850标准中的GOOSE/SV传输协议,实现了GOOSE/SV报文的发送和解析,用Qt应用程序框架开发了过程层通信测试组件。4、研究IEC 61850标准中MMS传输协议,实现ACSI对象和服务到MMS对象和服务的映射,实现MMS PDU的编解码,用Qt应用程序框架开发了支持MMS传输的站控层MMS客户端和站控层MMS服务器。本文实现的测试组件,能够模拟出真实变电站通信网络中所有类型的报文,用来测试智能变电站在线信息综合应用系统,组件还可以作为独立的报文分析工具软件服务于智能变电站的建设和运行维护。图形化展示组件实现了用“图形化+文字+过程描述+其他细节展示”的方法展示站内的各种在线信息的分析结果,使得运维人员可以直观全面的了解设备的功能实现过程以及运行状态。
[Abstract]:The process layer network and equipment are added to the intelligent substation based on IEC 61850 standard. The network transmission of the process layer equipment information makes the process layer equipment upload information and interactive information increase greatly.The client can master the working state of the secondary equipment more accurately.However, the information utilization technology of intelligent substation is still at the level of integrated automation substation.In the monitoring background, network message analyzer and other necessary to develop the intelligent use of information equipment, information capture, extraction, display methods.This single way of displaying information strip after information extraction does not reflect the realization of intelligent substation in the intelligent substation information analysis of the intelligent goal of the waste of valuable information resources.In order to make full use of all the message information transmitted on the intelligent substation communication network, an intelligent substation online information synthesis application system is designed.This paper introduces the functional components and test components needed to realize the core functions of the system.This paper introduces graphical display component and Goose / SVS (general-purpose object oriented substation event / sampling value) parsing component.This paper introduces the process layer communication test component and the MMS client and server for the station control layer communication test.The main work of this paper is to study the secondary system of intelligent substation, which includes the communication network structure of the secondary system and the communication mode between the devices.The ACSI information model of the equipment. 2, the method of graphically displaying the relay protection function of intelligent substation is studied.The Sugiyama algorithm is introduced emphatically.Based on the Sugiyama algorithm, the graphic display component. 3 of the online information synthesis application system is implemented. The GOOSE/SV transmission protocol in the IEC 61850 standard is studied, and the sending and parsing of the GOOSE/SV message is realized.The process layer communication test component. 4 is developed with QT application framework. The MMS transport protocol in IEC 61850 standard is studied. The mapping of ACSI object and service to MMS object and service is realized, and the encoding and decoding of MMS PDU is realized.The station control layer MMS client and the station control layer MMS server supporting MMS transmission are developed by using QT application program framework.The test module realized in this paper can simulate all kinds of messages in the real substation communication network and can be used to test the intelligent substation online information synthesis application system.The component can also be used as an independent packet analysis tool for the construction, operation and maintenance of intelligent substations.The graphical display component realizes the analysis results of various online information in the station by using the method of "graphical text process to describe other details".So that the operation and maintenance personnel can intuitively and comprehensively understand the function realization process and the running state of the equipment.
