【摘要】：電壓質量對于電力系統(tǒng)有著至關重要的作用,而電壓與無功又有很大關系。因此,保證無功的平衡對于電力系統(tǒng)安全穩(wěn)定的運行有著重要的意義。目前,動態(tài)無功補償技術得到了廣泛的應用,很多生產商的產品已能夠在一定程度上滿足平衡無功的需求。但現階段的無功補償方式主要是就地補償,屬于“點級”補償。隨著智能電網的快速發(fā)展,越來越需要多個無功補償裝置通過相互配合,實現更為高效合理的“系統(tǒng)級”補償。然而,由于缺少一種統(tǒng)一的標準,互操作性差和通訊規(guī)約不流通的問題制約了生產商產品的發(fā)展。因此,將變電站自動化系統(tǒng)唯一國際標準IEC61850應用到無功補償裝置中,對動態(tài)無功補償技術的發(fā)展具有重要意義,為實現智能電網環(huán)境下電力系統(tǒng)的安全穩(wěn)定運行奠定了基礎。本文根據國家智能電網研究院項目《基于安普平臺的IEC61850研究與應用》,對應用在巴西Rio Verde Norte站的無功補償裝置進行研究,基于IEC61850對其進行建模,生成配置文件,并最終實現通訊服務。首先,本文介紹了IEC61850通訊協(xié)議的內容,詳細分析了變電站的站控層、間隔層、過程層的分層信息模型,典型的數據自描述方法。研究了ACSI八大基本信息模型和他們對應的服務以及SCSM技術。以應用在巴西Rio Verde Norte站的無功補償裝置為例,對其基本模型結構、主要功能、以及調節(jié)控制方法做了分析,總結出了無功補償裝置的主要功能需求,將其解耦為告警、測量、控制、保護和故障錄波五個部分。采用面向對象的設計方法,將這些功能設計到無功補償IED邏輯構件中,并給出了工程開發(fā)的步驟。之后,本文根據標準中介紹的IEC61850信息模型,遵循建模的方法,依次從邏輯節(jié)點、數據、邏輯設備和服務器四個部分對無功補償IED進行建模。最終得到包含S1、G1、M1三個訪問點的服務器,以及LDO、CTRL、PROT、MEAS、 RCD、PI、SVLD七個邏輯設備和大量邏輯節(jié)點數據等。通過介紹變電站配置描述語言SCL和六種SCL文件以及它們的工程配置流程,重點分析了無功補償裝置ICD/CID文件的構建方法,分別從Header段、Communication段、IED段和DataTypeTemplates段對無功補償裝置的SCL文件進行配置。最后,本文對MMS進行了介紹,描述了利用MMS在客戶端和服務器之間的通信流程以及IEC61850與MMS對象的映射關系。重點研究了MMS-EASE Lite軟件包,編寫相關函數實現IEC61850對象與MMS對象的轉換,又通過datamap.cfg映射表,編寫相關函數來完成數據的映射,然后分別在客戶端與服務器端給出實現通訊的步驟,并最終完成了數據在客戶端與服務器之間的傳輸。
[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.
