【摘要】：输配电网作为电力系统的重要组成部分,完成电能的输送和分配,它的安全与稳定将直接影响人民生活水平乃至整个国民经济的发展。输、配电网具有节点多、范围广、数据量大等特点,而其系统规划、运行维护、仿真研究等又依赖于各种分析计算。该类型分析计算单凭人工难以完成。因此,结合当前输配电网实际情况,开发出一款通用性、可扩展性、交互性强的新型输配电网分析平台(软件)具有重要意义。为了提高电网分析软件的通用性、可扩展性及交互性,遵循IEC61970公共信息模型CIM对电力信息资源分层次建模;遵循IEC61970标准组件接口规范CIS设计平台数据访问接口;采用微软公司窗体通信框架WCF构建平台C/S通信。首先,对CIM、CIS内容进行了分析总结,并根据电网实际分析需求,提出了采用瘦客户端模式(C/S模式)的平台基本架构,并依次对其数据库、数据访问接口、通信相关做了说明;其后,按照IEC61970标准内容顺序,依次对数据访问公共服务CS、通用数据访问服务GDA和高速数据访问服务HSDA进行了详细设计;最后阐述了如何采用WCF技术构建平台客户端与服务端之间的通信方式。在Microsoft Visual Studio 2013.NET平台下用C#语言编写数据访问及通信原型程序以及客户端与服务端窗体应用程序,并将其和后台内存数据库(FastDB)及持久数据库(Microsoft SQL Server 2008)组件进行连接;通过客户端对某地区实际输配电网的结构数据进行编辑。编辑过程表明,客户端能快速准确地对服务器中存储的数据进行增、删、改、查操作,验证了数据访问服务组件的正确性和有效性。
[Abstract]:As an important part of electric power system, transmission and distribution network can transmit and distribute electric energy. Its safety and stability will directly affect people's living standard and even the development of the whole national economy. Distribution network is characterized by many nodes, wide range and large amount of data, and its system planning, operation and maintenance, simulation research and so on depend on all kinds of analysis and calculation. This type of analysis and calculation alone is difficult to complete. Therefore, it is of great significance to develop a new transmission and distribution network analysis platform (software) based on the current situation of transmission and distribution network. In order to improve the generality, expansibility and interactivity of the power network analysis software, it follows the IEC61970 common information model CIM to model the power information resources in different levels, and follows the IEC61970 standard component interface specification CIS design platform data access interface. C / S communication platform is constructed by Microsoft forms Communication Framework (WCF). Firstly, the content of CIMN CIS is analyzed and summarized, and according to the actual analysis demand of power grid, the basic structure of the platform using thin client mode (C / S mode) is put forward, and its database, data access interface and communication correlation are explained in turn. Then, according to the IEC61970 standard content order, the common data access service CSS, the general data access service GDA and the high-speed data access service HSDA are designed in turn. Finally, how to use WCF technology to construct the communication mode between client and server of platform is expounded. Under the platform of Microsoft Visual Studio 2013.NET, the prototype program of data access and communication and the application program between client and server are written in C # language, and connected with backstage memory database (FastDB) and persistent database (Microsoft SQL Server 2008). The structure data of the actual transmission and distribution network in a certain area are edited by the client. The editing process shows that the client can quickly and accurately add delete modify and check the data stored in the server and verify the correctness and effectiveness of the data access service component.
