【摘要】：实现电力系统信息化与智能化一直是电力行业发展的目标。为了实现不同电力系统间的信息交互与信息共享,国际电工委员会(International Electrotechnical Commission,IEC)制定了公共信息模型标准并且以此为基础拓展形成了IEC61970系列标准。近年来主要以风能、光能等清洁能源为发电基础的微电网得到快速发展。然而,各个微电网单位根据自身的需求建立了监控系统和能量管理系统,没有考虑与其它电力系统进行信息交互与共享的问题。在各个系统已经建成的既定事实下,为了保护已有投资需要尽可能小的减少对已建成系统的破坏,唯一的办法是对现有系统进行改造,使其符合公共信息模型这一标准,为将来可能的与其他电力系统进行信息交互与信息共享打下基础。本文首先对现有公共信息模型进行了研究,分析了模型中主要包结构以及包中类与类之间的几种关系,并将它们以框图的形式展示出来。针对现有的公共信息模型对微电网的部分电力对象缺乏相应的描述的问题,根据公共信息模型的扩展导则对微电网的主要组成部分以及与微电网监控系统相关的电力对象进行模型的扩展。然后以具体的微电网系统为研究对象,为了减小对现有已建成微电网监控系统的破坏同时又使其符合公共信息模型标准,以Microsoft SQL Server 2005数据库为平台根据相应的映射策略重新构造一个符合公共信息模型标准的数据库,并通过使用触发器技术、存储过程技术和数据库的定时作业实现了既有微电网监控系统数据库到新构造的符合公共信息模型标准的数据库数据的实时存储,使新构造的数据库能够实时的反映微电网系统的运行状态。最后利用JAVA语言开发了基于WEB的CIIM/XML数据解析器,利用该解析器把新构造的数据库的信息解析插入到原微网监控系统的数据库中,实现了数据库间信息的交互。在目前没有成熟的面向对象特性的数据库的现实条件下,采用对现有成熟的关系型数据库进行改造的方法,使其符合公共信息模型的面向对象的特性,并且实现了两个数据结构完全不同的数据库之间的数据的实时存储,对于公共信息模型的实际应用有一定的借鉴意义。
[Abstract]:Realization of power system information and intelligence has been the goal of the development of the power industry. In order to realize the information exchange and information sharing among different power systems, the International Electrotechnical Commission (IEC) has formulated the public information model standard and based on it, the IEC61970 series standards have been developed. In recent years, the microgrid, which is mainly based on clean energy such as wind energy and light energy, has been developed rapidly. However, each micro-grid unit has established a monitoring system and an energy management system according to its own needs, without considering the problem of information exchange and sharing with other power systems. In the context of the fact that systems have been established, in order to protect existing investments, the only way to minimize damage to established systems is to adapt existing systems to the standards of a public information model, Lay the foundation for possible information exchange and information sharing with other power systems in the future. In this paper, we first study the existing common information models, analyze the main packet structures in the model and the relationships between classes and classes in the package, and show them in the form of block diagrams. In order to solve the problem that the existing public information model lacks the corresponding description of some power objects in microgrid, According to the extension guidelines of public information model, the main components of microgrid and the power objects related to microgrid monitoring system are extended. Then take the specific microgrid system as the research object, in order to reduce the damage to the existing microgrid monitoring system and make it accord with the public information model standard. Using Microsoft SQL Server 2005 database as the platform, according to the corresponding mapping strategy, a database conforming to the standard of common information model is constructed, and the trigger technology is used to reconstruct the database. The stored procedure technology and the timing operation of the database realize the real-time storage of the existing microgrid monitoring system database to the newly constructed database data which conforms to the standard of the common information model. The newly constructed database can reflect the running state of microgrid system in real time. Finally, a CIIM/XML data parser based on WEB is developed by using JAVA language. The parser inserts the information of the newly constructed database into the database of the original micronetwork monitoring system, and realizes the information exchange between the databases. Under the condition that there is no mature object-oriented database at present, the method of transforming the existing mature relational database is adopted to make it conform to the object-oriented characteristics of the public information model. The real-time storage of data between two databases with completely different data structures is realized, which is useful for the practical application of the common information model.
