【摘要】：电压质量对于电力系统有着至关重要的作用,而电压与无功又有很大关系。因此,保证无功的平衡对于电力系统安全稳定的运行有着重要的意义。目前,动态无功补偿技术得到了广泛的应用,很多生产商的产品已能够在一定程度上满足平衡无功的需求。但现阶段的无功补偿方式主要是就地补偿,属于“点级”补偿。随着智能电网的快速发展,越来越需要多个无功补偿装置通过相互配合,实现更为高效合理的“系统级”补偿。然而,由于缺少一种统一的标准,互操作性差和通讯规约不流通的问题制约了生产商产品的发展。因此,将变电站自动化系统唯一国际标准IEC61850应用到无功补偿装置中,对动态无功补偿技术的发展具有重要意义,为实现智能电网环境下电力系统的安全稳定运行奠定了基础。本文根据国家智能电网研究院项目《基于安普平台的IEC61850研究与应用》,对应用在巴西Rio Verde Norte站的无功补偿装置进行研究,基于IEC61850对其进行建模,生成配置文件,并最终实现通讯服务。首先,本文介绍了IEC61850通讯协议的内容,详细分析了变电站的站控层、间隔层、过程层的分层信息模型,典型的数据自描述方法。研究了ACSI八大基本信息模型和他们对应的服务以及SCSM技术。以应用在巴西Rio Verde Norte站的无功补偿装置为例,对其基本模型结构、主要功能、以及调节控制方法做了分析,总结出了无功补偿装置的主要功能需求,将其解耦为告警、测量、控制、保护和故障录波五个部分。采用面向对象的设计方法,将这些功能设计到无功补偿IED逻辑构件中,并给出了工程开发的步骤。之后,本文根据标准中介绍的IEC61850信息模型,遵循建模的方法,依次从逻辑节点、数据、逻辑设备和服务器四个部分对无功补偿IED进行建模。最终得到包含S1、G1、M1三个访问点的服务器,以及LDO、CTRL、PROT、MEAS、 RCD、PI、SVLD七个逻辑设备和大量逻辑节点数据等。通过介绍变电站配置描述语言SCL和六种SCL文件以及它们的工程配置流程,重点分析了无功补偿装置ICD/CID文件的构建方法,分别从Header段、Communication段、IED段和DataTypeTemplates段对无功补偿装置的SCL文件进行配置。最后,本文对MMS进行了介绍,描述了利用MMS在客户端和服务器之间的通信流程以及IEC61850与MMS对象的映射关系。重点研究了MMS-EASE Lite软件包,编写相关函数实现IEC61850对象与MMS对象的转换,又通过datamap.cfg映射表,编写相关函数来完成数据的映射,然后分别在客户端与服务器端给出实现通讯的步骤,并最终完成了数据在客户端与服务器之间的传输。
[Abstract]:Voltage quality plays an important role in power system, and voltage and reactive power have a great relationship. Therefore, it is of great significance to ensure the balance of reactive power for the safe and stable operation of power system. At present, dynamic reactive power compensation technology has been widely used, many manufacturers' products have been able to meet the demand of balanced reactive power to some extent. But at present, reactive power compensation is mainly local compensation, which belongs to "point level" compensation. With the rapid development of smart grid, more and more reactive power compensators are needed to realize more efficient and reasonable "system level" compensation by cooperating with each other. However, due to the lack of a uniform standard, poor interoperability and lack of circulation of communication protocols constrain the development of producer products. Therefore, the application of IEC61850, the sole international standard of substation automation system, to reactive power compensator is of great significance to the development of dynamic reactive power compensation technology and lays a foundation for the safe and stable operation of power system under the environment of smart grid. In this paper, according to the research and application of IEC61850 based on Anpu platform, the reactive power compensation device applied in Rio Verde Norte Station in Brazil is studied, and the model is built based on IEC61850, and the configuration file is generated based on IEC61850. And finally realize the communication service. Firstly, the content of IEC 61850 communication protocol is introduced, and the hierarchical information model of substation control layer, interval layer, process layer and typical data self-description method are analyzed in detail. Eight basic information models of ACSI and their corresponding services as well as SCSM technology are studied. Taking the reactive power compensation device applied in the Rio Verde Norte station in Brazil as an example, the basic model structure, main functions and regulation control methods are analyzed, and the main functional requirements of the reactive power compensation device are summarized, which are decoupled to alarm and measured. Control, protection and fault recording five parts. These functions are designed into reactive power compensation IED logic components by using object-oriented design method, and the steps of engineering development are given. Then, according to IEC61850 information model introduced in the standard, following the method of modeling, this paper models reactive power compensation IED from four parts: logical node, data, logic device and server. Finally, a server containing three access points of S1 / G1 / M1, as well as seven logic devices and a large number of logical node data are obtained, such as LDO CTRLX PROTMEASS, RCDPIN SVLD and so on. By introducing substation configuration description language SCL and six SCL files as well as their engineering configuration flow, the construction method of reactive power compensation device ICD / CID file is analyzed. The SCL files of the reactive power compensator are configured from the header / Communication / IED and DataTypeTemplates respectively. Finally, this paper introduces MMS, describes the communication flow between client and server using MMS and the mapping relationship between IEC61850 and MMS object. This paper focuses on MMS-EASE Lite software package, writes the correlation function to realize the conversion between IEC61850 object and MMS object, and through the datamap.cfg mapping table, writes the correlation function to complete the data mapping, and then gives the steps to realize the communication between the client and the server. Finally, the data transfer between the client and the server is completed.
