【摘要】：在我國,電力是國民經(jīng)濟發(fā)展的重要能源,以火電為主的傳統(tǒng)發(fā)電方式,不僅消耗資源而且嚴重污染環(huán)境。同時,遠距離高電壓傳輸和大容量集中式發(fā)電的大電網(wǎng)存在運行難度大、運營成本高、調(diào)節(jié)能力弱的問題。而以風(fēng)能、太陽能、地?zé)崮艿确植际桨l(fā)電為主的,包含儲能設(shè)備、負載和控制裝置的微電網(wǎng)技術(shù)能夠節(jié)約能源、保護環(huán)境、減少發(fā)電成本、實現(xiàn)靈活供電。此外,將IEC 61850標準作為微電網(wǎng)通信的標準,能夠使不同廠家的不同設(shè)備進行互操作和實現(xiàn)信息共享。本論文研究基于IEC 61850的微電網(wǎng)監(jiān)控系統(tǒng),實現(xiàn)對分布式發(fā)電、儲能和負載狀態(tài)的實時綜合監(jiān)控。首先,論文對三相交流微電網(wǎng)系統(tǒng)的整體架構(gòu)進行了設(shè)計,由中央控制器連接底層的微電網(wǎng)系統(tǒng)硬件設(shè)備和上層的監(jiān)控系統(tǒng)。接著介紹了微電網(wǎng)系統(tǒng)的分層通信結(jié)構(gòu),將其分為調(diào)度管理層、集中控制層和就地控制層,其中在調(diào)度管理層采用的是MMS+TCP+以太網(wǎng)的通信架構(gòu)。之后對微電網(wǎng)監(jiān)控系統(tǒng)功能需求進行說明——設(shè)計一個基于 IEC 61850 標準 MMS(Manufacture Message Specification)服務(wù)的B/S(Browser/Server)模式的Web遠程監(jiān)控管理系統(tǒng)。然后對系統(tǒng)中所用到的主要通信技術(shù)和兩個Java中間件進行闡述。串口轉(zhuǎn)以太網(wǎng)中間件和SCADA(Supervisory Control and Data Acquisition)系統(tǒng)中間件,向上與 MMS 服務(wù)器通信,向下與底層的中央控制器通信。其次,論文采用IEC 61850標準對微電網(wǎng)系統(tǒng)進行面向?qū)ο蟮姆謱咏?將負責(zé)測控的中央控制器作為建模的IED(Intelligent Electronic Device),采用先逐步分解,再相互結(jié)合的建模思想,即以確定邏輯節(jié)點和數(shù)據(jù)、構(gòu)建邏輯設(shè)備、構(gòu)建服務(wù)器的先后順序來完成建模并利用變電站配置描述語言SCL(Substation Configuration description Language)建立 ICD(IED Capability Description)配置文件。本設(shè)計采用的是OpenIEC61850的開源代碼庫來支持運行整個IEC 61850和MMS服務(wù)程序。該庫采用Java語言編寫,面向?qū)ο蟮恼Z言更符合IEC 61850面向?qū)ο蟮慕Ｌ攸c,而且具有平臺無關(guān)性,能夠運行在Windows、Linux等操作系統(tǒng)下。MMS服務(wù)器向MMS客戶端上傳電氣數(shù)據(jù)、報警信息采用MMS的報告服務(wù),MMS客戶端向MMS服務(wù)器下發(fā)控制指令采用MMS的控制服務(wù)。為了與底層采用的Modbus協(xié)議兼容,需要在MMS服務(wù)器中進行Modbus與IEC 61850協(xié)議的相互映射轉(zhuǎn)換。再次,論文對Web監(jiān)控管理系統(tǒng)進行了較為詳細的設(shè)計,對其整體功能架構(gòu)、軟件結(jié)構(gòu)和MySQL數(shù)據(jù)庫進行了設(shè)計。接著對用到的Struts 2、JDBC(Java Data Base Connectivity)、Servlet、JSP(Java Server Pages)等相關(guān) Java Web 技術(shù)進行介紹。然后對Web監(jiān)控管理系統(tǒng)各個管理功能的設(shè)計結(jié)果進行展示和分析。監(jiān)控人員可以通過實時監(jiān)測界面查看微電網(wǎng)系統(tǒng)實時的運行數(shù)據(jù)和狀態(tài),管理員可以根據(jù)發(fā)電計劃通過實時控制界面下達控制指令至中央控制器。最后,論文介紹了微電網(wǎng)系統(tǒng)所采用的硬件平臺和服務(wù)器平臺,然后按照監(jiān)控系統(tǒng)的啟動運行步驟來對系統(tǒng)的MMS通信過程和監(jiān)控功能進行了測試和總結(jié)分析,系統(tǒng)各個功能模塊運行良好,滿足設(shè)計要求。本論文對微電網(wǎng)監(jiān)控和IEC 61850標準的研究和應(yīng)用具有一定的參考價值。
[Abstract]:In China, power is an important energy for national economic development, and traditional power generation mode based on thermal power is not only consuming resources but also seriously polluting the environment. At the same time, the large power grid with high-voltage transmission and large-capacity centralized power generation has the problems of large operation difficulty, high operation cost and weak regulation capacity. And the micro-grid technology containing the energy storage equipment, the load and the control device can save energy, protect the environment, reduce the power generation cost and realize flexible power supply. In addition, the IEC 61850 standard is used as the standard for micro-grid communication, and different equipment of different manufacturers can be used for mutual operation and information sharing. This paper studies the micro-grid monitoring system based on IEC 61850, and realizes the real-time comprehensive monitoring of distributed power generation, energy storage and load state. Firstly, the paper designs the whole structure of the three-phase AC micro-grid system, and the central controller is connected with the hardware equipment of the micro-grid system and the monitoring system of the upper layer. The hierarchical communication structure of the micro-grid system is introduced, which is divided into the dispatching management layer, the centralized control layer and the local control layer, wherein the communication structure of the MMS + TCP + Ethernet is adopted at the dispatching management layer. The function requirement of the micro-grid monitoring system is described in this paper. A Web remote monitoring and management system based on the B/ S (Browser/ Server) mode of IEC 61850 standard MMS is designed. The main communication technologies and two Java middleware used in the system are then described. The middleware of the serial-to-Ethernet middleware and the SCADA (Remote Control and Data Acquisition) system is in communication with the MMS server and is in communication with the central controller of the bottom layer. Secondly, the object-oriented hierarchical modeling of the micro-grid system is carried out by using the IEC 61850 standard, and the central controller, which is responsible for the measurement and control, is used as an IED (Intelligent Electronic Device), which is firstly decomposed and then combined with each other, i.e., the logical node and the data are determined, and the logical device is constructed. The building server is constructed in order to complete the modeling and set up an ICD (IED Capability Description) configuration file using the substation configuration description language. This design uses the open source library of OpenIEC61850 to support the running of the entire IEC 61850 and MMS service routines. The library is written in the Java language, and the object-oriented language is more consistent with the object-oriented modeling of IEC 61850, and the library is independent of the platform and can run under the operating system such as Windows, Linux and the like. The MMS server uploads the electric data to the MMS client, the alarm information adopts the report service of the MMS, and the MMS client issues a control instruction to the MMS server to adopt the control service of the MMS. In order to be compatible with the Modbus protocol used at the bottom layer, the mutual mapping conversion of the Modbus and the IEC 61850 protocol is required in the MMS server. Thirdly, the paper designs the Web monitoring and management system in detail, and designs the whole function structure, software structure and MySQL database. Then, the related Java Web technologies such as Struts 2, JDBC (Java Data Base Connectivity), Servlet, JSP (Java Server Pages) are introduced. And then the design results of various management functions of the Web monitoring and management system are shown and analyzed. The monitoring personnel can view the real-time running data and status of the micro-grid system through the real-time monitoring interface, and the administrator can issue control instructions to the central controller through the real-time control interface according to the power generation plan. In the end, the hardware platform and the server platform used in the micro-grid system are introduced, then the MMS communication process and the monitoring function of the system are tested and summarized according to the start-up operation step of the monitoring system, and the functional modules of the system are in good operation and meet the design requirements. This paper has certain reference value to the research and application of the micro-grid monitoring and IEC 61850 standard.
