【摘要】：故障信息处理系统是对电网自动化远程管理的数据平台,它能够实时上传和远程采集变电站内电网运行数据,为调度工作人员分析故障原因,处理故障事件,评价继电保护设备提供有力支持,同时大大提高了电网管理自动化的程度,能够快速处理故障,稳定电网运行状况,具有很高的经济价值与社会价值。本系统基于IEC61850标准规范,深入研究了IEC61850标准的背景,组成,结构以及建模思想等,详细阐述了IEC61850标准对智能设备对象建模的方法,并举例说明。针对故障信息处理系统数据量庞大且实时性要求高的特点,本系统引入了实时数据库与传统数据库相结合的方法,使得变电站继电保护设备的数据采集能够稳定,安全,快速地传输到主站调度工作人员手中,大大提高了系统的实时性与稳定性。通信服务作为本系统与变电站之间的桥梁,本文着重对主站通信机制进行了详细说明,引入了UDP通信方式,并对其报文结构封装做了详细解释与说明。变电站内实时监视继电保护设备的故障录波器数据被我们作为故障诊断的重要依据,借助于分析故障录波文件,本文提出了以突然电流变化量为重要依据的故障判断方法,并给出相应公式与算法,能够基本判断故障类别,并从单端与双端测距两种方法来综合计算故障距离,供继保人员参考研究。故障信息处理系统充分利用计算机技术,大大提高了电网故障处理的时效,提高了故障判断的可靠性,同时增加了调度中心的数据处理能力。
[Abstract]:Fault information processing system is a data platform for remote management of power network automation. It can upload and collect data of power grid operation in substation in real time, analyze the cause of failure and deal with fault events for dispatching staff. Evaluation of relay protection equipment to provide strong support, at the same time greatly improve the degree of automation of power grid management, can quickly deal with failures, stability of power grid operation. This system is based on the IEC61850 standard specification, in-depth study of the background, composition, structure and modeling ideas of the IEC61850 standard. The modeling method of intelligent device object in IEC61850 standard is described in detail, and an example is given to illustrate the characteristics of large amount of data and high real-time requirement of fault information processing system. This system introduces the method of combining real-time database with traditional database, which makes the data collection of substation relay protection equipment stable, safe and fast to the master station dispatching staff. Communication service is a bridge between the system and the substation. The communication mechanism of the main station is explained in detail in this paper, and the UDP communication mode is introduced. And the encapsulation of the message structure is explained in detail. The fault recorder data of real-time monitoring relay protection equipment in substation is regarded as the important basis of fault diagnosis by analyzing the fault recording file. In this paper, a fault judgment method based on the change of sudden current is proposed, and the corresponding formulas and algorithms are given, which can be used to judge the types of faults. The fault information processing system makes full use of computer technology to calculate fault distance synthetically from single terminal and double terminal location, which greatly improves the time limit of power network fault processing. The reliability of fault judgment is improved, and the data processing ability of dispatching center is increased.
