【摘要】：变电站是电力系统重要组成部分，智能电网的发展给变电站技术水平提出了更高的要求。变电站经历了传统变电站、数字化变电站和智能变电站三个发展阶段。目前智能变电站已经得到了广泛应用，由于IEC61850的应用，智能变电站智能设备之间的互操作性已经能够很好的实现。但是在实际变电站工程当中采用人工配置的方式效率较低，不同厂家生产设备模型之间的兼容性也存在缺陷。另外，智能设备的更换或增加可能需要对全站的智能设备重新配置。考虑到目前变电站配置方式对技术人员的技术水平的依赖，智能变电站的维护和扩建将遇到更多的困难。针对以上问题，论文研究一种智能变电站智能设备的自动配置方法，即对智能设备的互换性实现方法展开研究，以期实现智能设备的“即插即用”。首先，论文分析了IEC61850第二版更新的内容，在此基础上研究了变电站和智能设备的建模方法。由于IEC61850给出的建模方法并没有明确逻辑设备和逻辑节点是服务的接受方还是提供方，不利于模型的自动配置，本文对智能设备模型的逻辑设备和逻辑节点服务进行了定义，对资源对象的提供还是需求进行了区分。提出了智能变电站智能设备互换性过程。其次，论文对国内外广泛应用的“即插即用”技术进行分析，分别研究了PNP、UPnP和Jini的技术特点。通过分析发现，Jini跨平台、面向对象、基于服务、分布式的特点使得其能够适应智能变电站环境。本文提出使用IEC61850和Jini技术相结合来实现智能设备的自动配置。最后，论文建立了符合国内标准的变电站模型，将互换性的实现过程分为两次模型的关联，一是智能设备模型与智能变电站模型的关联，确定了智能设备的功能间隔，为智能二次设备的关联提供依据；二是智能设备模型之间的关联，确定了设备之间的数据交互关系。针对某些智能设备在智能变电站只应用了部分功能，论文对服务的有效性进行了定义，防止将模型中描述了但是未启用的部分服务加入到自动配置的过程。论文运用JDK和Jini搭建了互换性验证平台，仿真了智能设备的互换性实现过程，，按要求自动生成了智能设备的配置文件，验证了本文提出的互换性实现方法的可行性和有效性。
[Abstract]:Substation is an important part of power system. The development of smart grid puts forward higher requirements for substation technical level. Digital substation and intelligent substation are three stages of development. At present, intelligent substation has been widely used, because of the application of IEC61850, The interoperability between intelligent devices in intelligent substations has been realized well. But in actual substation engineering, the manual configuration is inefficient, and the compatibility among the models of different manufacturers is also defective. The replacement or increase of smart devices may require the reconfiguration of smart devices throughout the station. Considering the dependence of the current substation configuration on the technical level of technicians, The maintenance and expansion of intelligent substation will meet more difficulties. In view of the above problems, this paper studies an automatic configuration method of intelligent equipment in intelligent substation, that is, the interchangeability realization method of intelligent equipment. In order to achieve the intelligent device "plug and play". First of all, the paper analyzes the content of the second edition of IEC61850, On this basis, the modeling method of substation and intelligent device is studied. Because the modeling method given by IEC61850 is not clear whether the logical device and the logical node are the recipient or provider of the service, it is not conducive to the automatic configuration of the model. In this paper, the logic device and logic node service of intelligent device model are defined, the resource object is provided or the requirement is distinguished, and the interchangeability process of intelligent equipment in intelligent substation is proposed. Secondly, the paper analyzes the "plug and play" technology which is widely used at home and abroad, and studies the technical characteristics of PNPP and Jini respectively. Through the analysis, it is found that Jini is cross-platform, object-oriented and service-based. The distributed system can adapt to the environment of intelligent substation. In this paper, the combination of IEC61850 and Jini technology is proposed to realize the automatic configuration of intelligent equipment. Finally, the paper establishes the substation model which conforms to the domestic standard, divides the interchangeability realization process into two models correlation, one is the intelligent device model and intelligent substation model correlation, determines the intelligent device function interval. It provides the basis for the association of intelligent secondary devices, the correlation between intelligent device models, and determines the data interaction between devices. In view of some intelligent devices, only some functions are applied in intelligent substations. In this paper, the validity of services is defined to prevent some services described but not enabled in the model from being added to the process of automatic configuration. An interchangeability verification platform is built by using JDK and Jini. The interchangeability realization process of intelligent equipment is simulated and the configuration file of intelligent equipment is automatically generated according to the requirements. The feasibility and effectiveness of the interchangeability realization method proposed in this paper are verified.
