【摘要】 基于电网广域信息的电力系统协调保护与控制是解决长期困扰电业部门电网安全、稳定运行问题的重要出路,而常规电力远动系统从数据传输速度和灵活性方面无法满足电力系统协调保护与控制对实时数据交换的要求。鉴于目前光缆SDH 电力数据通信专网在我国电力系统已初具规模,建立基于广域网的电力远动系统已具备物质基础,本文结合IEC 制定的变电站网络化最新通信标准IEC 61850,对新型电力远动系统网络结构下的远动信息传输方式进行了深入的研究和探索工作, 主要研究成果如下: 1. 对将IEC 61850 应用于新型远动系统的实现方法进行了研究,首次提出了基于IEC 61850 并能兼容原有系统的远动信息传输系统网络结构、设备通信模式、设备远动通信信息模型和服务模型,同时给出了IEC 60870-101/104 向IEC 61850过渡时采用通信服务代理的方案及其实现方法。2. 提出了远动信息传输多Agent 系统结构模板--IED_Agent 和Dispatching_ Agent,Agent 模板将IEC 61850 标准与远动传输任务以及软件Agent 特性进行了有机结合。利用认知逻辑系统理论对模板各模块之间的组织方式、控制结构、数据流向和状态的动态变化过程进行了形式化描述,根据该形式化描述,提出了采用面向对象和子类构件技术的远动通信Agent 实现方法,深入研究了主要构件的实现方法和技术。3. 为解决远动系统的分布异构和快速传输问题,提出了将IED 远动通信服务模型映射到实时CORBA—TAO 技术的方法。深入研究了TAO 的实时事件服务机制及分布式实时Qos 方案在两类Agent 的通信机制和策略中的应用,尤其在远动报文优先级的分配、处理和向CORBA 优先级的映射等问题上提出了相应的解决方法。4. 通过实验室内电力远动原型系统的开发和测试,验证了多Agent 系统中各类基于IEC 61850 的Agent 模型的正确性以及基于TAO 的远动通信实现方法的可行性和优越性。5. 为便于调度端对IED 及其监测数据的管理,以及为实现IED 的即插即用,提出了适用于电网远动系统的IED 自描述文档的Schema 模式,并给出了相应的文档样例。更多还原

【Abstract】 Coordinated protection and control for power system based on power grid wide area information is the important approach to solving the problem of safety and steady operation of power grid which worry the electric power industry department for a long time, but the data transmission rate and flexibility of conventional telecontrol system for power system can not meet the requests of real-time data exchange of Coordinated protection and control for power system. Whereas the conditions that optical fiber cable SDH power data communication network has been on a scale at present and there is substance foundation for establishing the telecontrol system for power system based on Wide Area Network (WAN), and on basis of the newest international standard of IEC--communication networks and systems in substations, the transmission mode of telecontrol information under the new network structure of telecontrol system has been studied deeply in the paper. The main contributions are: (1) By studying the implementations of IEC 61850 applied to new telecontrol system for power system, the network structure, communication mode of IED, telecontrol communication information model and services model of IED of the telecontrol information transmission system which based on IEC 61850 and being capable of the old system have been proposed for the first time, and the scheme and implementations of by adopting communication proxy server to realize the IEC 60870-101/104-to-IEC 61850 transition. (2) Structure models of Multi-Agent system for tele-information transmissoin--IED_Agent and Dispatching_Agent have been proposed, the Agent-templates have combined organically the IEC 61850, telecontrol transmission task and the characteristics of software Agent. The organization mode, control structure, data flow and dynamic changing process of state among the components of model of the main Agent have been described formally by the theories of epistemic logic system. On basis of the formalization description, the methods of adopting the technologies of Object-Oriented and sub-class component to realize the telecontrol communication Agents have been presented, and the technologies and methods of realizing the main components of Agents have been researched deeply. (3) To solve the problems of the heterogeneous distribution and transmission speed in the telecontrol system, a method of mapping the IED’s telecontrol communication service model to TAO, a Real-time CORBA technology, has been proposed. The problems that how the mechanisms of TAO such as Real-time Event Service and distributed real-time Qos have been applied to the communication mechanisms and strategies for two types of Agents have been researched deeply, in which especially the methods about the distribution, handle and mapping to the CORBA priority of the telecontrol messages priorities have been given. (4) The validity of each type of Agent models based on IEC 61850 in the Multi-Agent system and the feasibility and advantagy of the implementations based on TAO of telecontrol communication have been proven through developing a simple prototype system for power system telecontrol and making tests on it. (5) To make it easy to manage the IED and its monitoring data for dispatching centre and realize the plug and play of IED, the Schema of IED self-description document which adapted to the telecontrol system of power grid has been presented and the corresponding document sample has been given.更多还原
