【摘要】：新一代智能变电站动态记录装置是基于电力行业标准DL/T 553-201X的要求提出的,该标准将数字化故障录波器与网络记录分析装置功能融合,并统称为“电力系统动态记录装置”。本论文将从剖析传统故障录波器的功能与实现出发,加上对基于IEC-61850的数字化变电站技术的研究,以及网络记录分析装置功能与实现的探索,研究如何设计出满足新一代智能变电站要求的动态记录装置软件。本文主要研究内容及成果包括:1.研究了海量数据的快速存储与检索方案,海量数据分为两类:原始网络报文数据和稳态录波数据。设计了一种自定义大文件系统,针对这两类海量的带时标数据,通过时标进行索引,生成索引文件,该方式可实现在4T的数据中快速检索出所需要的数据片段,检索时间一般不会超过2秒,有效避免了数据因重复循环存储导致的读写性能衰减。2.研究了暂态故障录波功能的设计方法,设计并实现了借助傅立叶变换算法(一种时域到频域变换方法)对离散采样数据进行分析,进而实现各类启动判据的算法和流程。由于系统的实时运算量较大常规的计算方法可能导致CPU负荷过重,甚至系统崩溃,为提高运算效率设计了一种基于滑动窗口的傅立叶变换计算方法,经验证可以将这部分计算速度提高20倍左右。3.研究了电力系统故障波形分析软件的具体功能、设计原理与实现方法,研究了波形分析、相量分析、谐波分析以及功率分析等内容。4.研究了一种进程通讯代理机制,用于解决各进程间通讯及协作问题以及Telnet(一种远程登陆服务的标准协议)维护手段,实现在一个TCP端口上的两类应用服务复用。经中国电科院型式试验测试,软件和系统满足了新一代变电站的各项性能要求。
