【摘要】：變電設備是電力系統中一個重要的組成部分,變電設備的監測與維護本身帶有一定的危險性,變電設備是否能夠穩定工作直接影響到人們的生活,因此對變電設備狀態進行監測具有很強的必要性。對變電設備進行實時狀態監測,能夠對變電設備的故障進行實時診斷和分析,及時進行修復,能夠確保變電設備正常運行,保障人們的生活。本文針對變電設備狀態監測技術進行了較深入的研究,并實現一套基于Java技術的變電設備狀態監測系統,對提升電網智能化水平、實現變電設備狀態在線運行管理具有積極而深遠的意義。在對某電力公司實際工作情況進行調研的基礎上,對日常變電設備狀態監測管理工作的流程進行了科學地梳理和分析,根據管理的目標、內容、規模等情況,從系統論的觀點出發,運用軟件工程的設計方法建立起系統模型。本項目采用Java技術和Oracle數據庫技術作為開發工具,按照系統開發的原則,采用B/S結構架構進行軟件設計。在開發過程中以需求分析為基礎,采取模塊化設計思想,對系統的角色和功能進行了詳細劃分,并明確了用戶可交互功能,并對每個功能模塊進行了詳細的設計,同時針對變電設備狀態監測的特點,對系統數據庫的概念結構和邏輯結構進行了詳細設計。此外,論文對系統功能的詳細實現過程進行了重點闡述,并介紹了部分關鍵技術和系統的測試情況。變電設備狀態監測系統實現了裝置管理、系統管理、綜合展示、運行監視、綜合查詢、統計報表等功能,緊貼該公司變電設備管理工作的實際情況,實現了業務操作的全面信息化。最后,采用先進測試方法,對系統進行功能測試和性能分析。系統投入到電力公司進行了試運行,性能穩定,滿足了當前變電設備狀態監測的需求,達到了預期目標。
[Abstract]:Substation equipment is an important part of power system. The monitoring and maintenance of substation equipment have certain danger. Whether the substation equipment can work stably will directly affect people's life. Therefore, it is necessary to monitor the state of substation equipment. The real-time state monitoring of substation equipment can diagnose and analyze the fault of substation equipment in real time and repair it in time. It can ensure the normal operation of substation equipment and ensure people's life. In this paper, the condition monitoring technology of substation equipment is studied deeply, and a set of transformer equipment condition monitoring system based on Java technology is realized, which can improve the intelligence level of power network. It is of great significance to realize the online operation management of substation equipment. On the basis of investigating the actual working situation of a certain electric power company, this paper scientifically combs and analyzes the flow of daily transformer equipment condition monitoring and management, according to the management target, content, scale and so on. From the point of view of system theory, the system model is established by using the design method of software engineering. This project adopts Java technology and Oracle database technology as the development tool, according to the principle of system development, adopts the structure of B / S to carry on the software design. In the process of development, based on requirement analysis, the roles and functions of the system are divided in detail by adopting the modular design idea, and the interactive functions of the users are defined, and each functional module is designed in detail. At the same time, the conceptual structure and logical structure of the system database are designed in detail according to the characteristics of transformer equipment condition monitoring. In addition, the implementation process of the system function is described in detail, and some key technologies and system testing are introduced. The substation equipment condition monitoring system has realized the functions of device management, system management, comprehensive display, operation monitoring, comprehensive inquiry, statistical report and so on. It is closely related to the actual situation of the substation equipment management work in the company. The full information of business operation is realized. Finally, the advanced test method is used to test the function and performance of the system. The system has been put into trial operation in electric power company, and its performance is stable, which meets the needs of current transformer equipment condition monitoring and achieves the expected goal.
