【摘要】：新一代智能變電站動態(tài)記錄裝置是基于電力行業(yè)標準DL/T 553-201X的要求提出的,該標準將數(shù)字化故障錄波器與網(wǎng)絡記錄分析裝置功能融合,并統(tǒng)稱為“電力系統(tǒng)動態(tài)記錄裝置”。本論文將從剖析傳統(tǒng)故障錄波器的功能與實現(xiàn)出發(fā),加上對基于IEC-61850的數(shù)字化變電站技術的研究,以及網(wǎng)絡記錄分析裝置功能與實現(xiàn)的探索,研究如何設計出滿足新一代智能變電站要求的動態(tài)記錄裝置軟件。本文主要研究內(nèi)容及成果包括:1.研究了海量數(shù)據(jù)的快速存儲與檢索方案,海量數(shù)據(jù)分為兩類:原始網(wǎng)絡報文數(shù)據(jù)和穩(wěn)態(tài)錄波數(shù)據(jù)。設計了一種自定義大文件系統(tǒng),針對這兩類海量的帶時標數(shù)據(jù),通過時標進行索引,生成索引文件,該方式可實現(xiàn)在4T的數(shù)據(jù)中快速檢索出所需要的數(shù)據(jù)片段,檢索時間一般不會超過2秒,有效避免了數(shù)據(jù)因重復循環(huán)存儲導致的讀寫性能衰減。2.研究了暫態(tài)故障錄波功能的設計方法,設計并實現(xiàn)了借助傅立葉變換算法(一種時域到頻域變換方法)對離散采樣數(shù)據(jù)進行分析,進而實現(xiàn)各類啟動判據(jù)的算法和流程。由于系統(tǒng)的實時運算量較大常規(guī)的計算方法可能導致CPU負荷過重,甚至系統(tǒng)崩潰,為提高運算效率設計了一種基于滑動窗口的傅立葉變換計算方法,經(jīng)驗證可以將這部分計算速度提高20倍左右。3.研究了電力系統(tǒng)故障波形分析軟件的具體功能、設計原理與實現(xiàn)方法,研究了波形分析、相量分析、諧波分析以及功率分析等內(nèi)容。4.研究了一種進程通訊代理機制,用于解決各進程間通訊及協(xié)作問題以及Telnet(一種遠程登陸服務的標準協(xié)議)維護手段,實現(xiàn)在一個TCP端口上的兩類應用服務復用。經(jīng)中國電科院型式試驗測試,軟件和系統(tǒng)滿足了新一代變電站的各項性能要求。
[Abstract]:The new generation of intelligent substation dynamic recording device is based on the requirements of the electric power industry standard DL/T 553-201X. The standard combines the function of the digital fault recorder and the network record analysis device, and it is called the dynamic recording device of the power system. This paper will start from the function and implementation of the analysis of the fault recorder. Based on the research of digital substation technology based on IEC-61850 and the exploration of the function and Realization of network recording and analysis device, this paper studies how to design a dynamic recording device to meet the requirements of a new generation of intelligent substation. The main contents and results of this paper include: 1. research on the fast storage and retrieval scheme of sea data, mass number It is divided into two categories: the original network message data and the steady state recording data. A custom large file system is designed to index the two kinds of massive data with time standard and index the index files through the time standard. This method can quickly retrieve the required data fragments from the 4T data, and the retrieval time is generally not more than 2 seconds. There are no more than 2 seconds in the retrieval time. It avoids the design method of transient fault recording function based on the read write performance attenuation.2. caused by repeated cyclic storage, and designs and implements the analysis of discrete sampling data with the help of Fu Liye transform algorithm (a time domain to frequency transformation method), and then realizes the algorithm and process of various classes of starting criteria. In order to improve the efficiency of CPU, a kind of Fu Liye transform calculation method based on sliding window is designed to improve the efficiency of the calculation, and the calculation speed of this part can be increased by about 20 times.3. to study the specific function of the power system fault waveform analysis software. Principles and implementation methods, research on waveform analysis, phasor analysis, harmonic analysis and power analysis,.4. studies a process communication agent mechanism, which is used to solve communication and collaboration between various processes and the maintenance means of Telnet (a standard protocol for remote landing services) to implement two kinds of application services on a TCP port. Through the type test test of China Electric Power Institute, the software and system meet the performance requirements of the new generation substation.
