【摘要】：公用配电变压器的智能化是配网自动化建设的重要内容之一,同时对智能公用配电变压器进行监测与控制也是提高电能质量,保障供电可靠性的要求。为了实现对公变的监控,必须借助一个自动化的监控系统。本课题对这个监控系统进行研究,提出相应的软、硬件设计思路以及其实现方式。本文首先分析了当前国内外配网自动化的建设情况和公变的智能化以及智能终端的应用现况。其次对公变的终端测控系统进行了设计,提出了整体设计结构和基本的功能要求。再次,对终端监控系统的主控模块进行了设计,主要包括了核心控制芯片、电源模块、时钟模块、存储模块、电能采样计量模块等；接着说明了主控模块的软件设计。再者,对系统的功能模块进行设计,主要有电能数据的计算方式,无功补偿功能的实现,智能保护开关模块以及开关量输入输出模块等。最后对公变的主站监控系统的软件设计进行了说明,提出了主站软件的总估设计框架,主站与终终端之间的通信设计,数据库管理软件的设计等。通过公变智能监控系统的设计,对公用配电变压器的管理要求和功能需求有了一个全面的把握；通过功能设计、硬件选型搭配、软件编程调试,实现了公变智能监控系统,并在湖州配电网运行管理中得以应用。通过一段时间的运行,公变智能监控系统基本实现了设计目标和功能需求；该系统的应用,进一步提高了湖州公用配变的管理水平,促进了该地区配电网自动化水平的提升。
[Abstract]:The intelligentization of public distribution transformer is one of the important contents of distribution automation construction. At the same time, monitoring and control of intelligent public distribution transformer is also the requirement of improving power quality and ensuring power supply reliability. In order to realize the monitoring of public transformer, we must use an automatic monitoring system. In this paper, the monitoring system is studied, and the corresponding software and hardware design ideas and its implementation are put forward. Firstly, this paper analyzes the construction of distribution network automation at home and abroad, the intelligentization of common-transformer and the application status of intelligent terminal. Secondly, the terminal measurement and control system of public transformer is designed, and the overall design structure and basic functional requirements are put forward. Thirdly, the main control module of the terminal monitoring system is designed, including the core control chip, power supply module, clock module, storage module, power sampling and measurement module. Then, the software design of the main control module is explained. Furthermore, the functional modules of the system are designed, including the calculation of power data, the realization of reactive power compensation function, the intelligent protection switch module and the switch quantity input and output module and so on. Finally, the software design of master station monitoring system of common-transformer is explained, and the design frame of master station software estimation, the communication design between master station and terminal, and the design of database management software are put forward. Through the design of public transformer intelligent monitoring system, the management requirements and functional requirements of public distribution transformer are comprehensively grasped. Through function design, hardware selection and matching, software programming and debugging, the intelligent monitoring system of public transformer is realized, and it is applied in the operation and management of Huzhou distribution network. Through running for a period of time, the intelligent monitoring system of public transformer has basically realized the design goal and function requirement, and the application of this system has further improved the management level of Huzhou public distribution transformer and promoted the automation level of distribution network in this area.
