【摘要】：智能變電站故障錄波系統(tǒng)是針對當(dāng)前智能電網(wǎng)的發(fā)展而設(shè)計(jì)開發(fā)的。當(dāng)電網(wǎng)發(fā)生故障或受到擾動(dòng)時(shí),故障錄波裝置會記錄電網(wǎng)電壓、電流以及保護(hù)動(dòng)作情況,得到大量非常有研究價(jià)值的數(shù)據(jù),通過分析這些數(shù)據(jù)可以得到電網(wǎng)的各種狀態(tài)參數(shù),如電壓、電流、有功、無功和頻率等,以便分析事故原因、得出事故對策。故障錄波數(shù)據(jù)分析系統(tǒng)對保證電力系統(tǒng)安全可靠運(yùn)行起著十分關(guān)鍵的作用,它已成為電力系統(tǒng)自動(dòng)化的重要組成部分。智能變電站的出現(xiàn)不僅促進(jìn)和推動(dòng)了故障錄波技術(shù)的發(fā)展,在錄波配置、采樣方式和接線方式等方面進(jìn)行改進(jìn),而且也對錄波技術(shù)提出了更高的要求。本文提出的智能變電站錄波數(shù)據(jù)分析系統(tǒng)基于一體化監(jiān)控平臺,其基本結(jié)構(gòu)由數(shù)據(jù)采集和記錄系統(tǒng)、數(shù)據(jù)傳輸系統(tǒng)、數(shù)據(jù)分析系統(tǒng)、數(shù)據(jù)管理系統(tǒng)構(gòu)成。數(shù)據(jù)采集和記錄系統(tǒng)采用嵌入分布式錄波方法生成錄波文件,數(shù)據(jù)傳輸系統(tǒng)將錄波文件傳送給數(shù)據(jù)分析和數(shù)據(jù)管理系統(tǒng),數(shù)據(jù)分析系統(tǒng)對錄波文件進(jìn)行包括波形展示、電壓電流幅值相位計(jì)算、保護(hù)動(dòng)作特性分析等處理,數(shù)據(jù)管理系統(tǒng)采用文件管理技術(shù)對錄波源文件和分析結(jié)果文件進(jìn)行管理。數(shù)據(jù)分析功能包括基本分析功能和高級分析功能。基本分析功能包含兩部分：一是波形展示,即將錄波文件中各通道的采樣值直接展示出來,從而獲取故障發(fā)生時(shí)刻、故障維持時(shí)間、故障切除時(shí)刻,判斷故障發(fā)生相別等；二是從數(shù)據(jù)文件中提取固定時(shí)間段的基本電氣量,比如電壓電流基波和各次諧波的幅值、相位等,通過左右光標(biāo)的移動(dòng)實(shí)現(xiàn)數(shù)據(jù)窗口的推移,得出這些電氣量隨時(shí)間變化的值,為電力系統(tǒng)故障分析提供依據(jù)。高級功能包括距離保護(hù)動(dòng)作特性分析和縱聯(lián)保護(hù)動(dòng)作特性分析。其中距離保護(hù)動(dòng)作特性分析功能根據(jù)故障錄波文件得到測量阻抗隨時(shí)間變化的值以及阻抗動(dòng)作特性。縱聯(lián)保護(hù)動(dòng)作特性分析包括方向式縱聯(lián)保護(hù)特性分析和縱聯(lián)電流差動(dòng)保護(hù)特性分析,分別通過計(jì)算功率方向元件相位和差動(dòng)電流、制動(dòng)電流得到保護(hù)動(dòng)作特性,為保護(hù)動(dòng)作分析提供依據(jù)。利用VC++開發(fā)語言在vs2008和Qt4.3.0混合平臺上對上述功能進(jìn)行了開發(fā),并在Windows操作系統(tǒng)下采用現(xiàn)場測試和實(shí)驗(yàn)室測試方案分別對基本分析功能和高級分析功能進(jìn)行測試。測試結(jié)果表明,該系統(tǒng)能夠充分有效地利用故障錄波數(shù)據(jù),真實(shí)地再現(xiàn)故障和異常運(yùn)行時(shí)的電氣量變化過程。
[Abstract]:The fault recording system of intelligent substation is designed and developed according to the development of smart grid. When the power network fails or is disturbed, the fault recording device will record the voltage, current and protection action of the power network, and obtain a large number of very valuable data. By analyzing these data, we can get the various state parameters of the power network. Such as voltage, current, active power, reactive power and frequency, in order to analyze the cause of the accident, the accident countermeasures. Fault recording data analysis system plays a key role in ensuring the safe and reliable operation of power system. It has become an important part of power system automation. The emergence of intelligent substation not only promotes the development of fault recording technology, but also improves the recording configuration, sampling mode and wiring mode, and puts forward higher requirements for recording technology. The intelligent substation recording data analysis system is based on an integrated monitoring platform. Its basic structure is composed of data acquisition and recording system, data transmission system, data analysis system and data management system. The data acquisition and recording system uses embedded distributed recording method to generate the recording file. The data transmission system transmits the recording file to the data analysis and data management system. The data analysis system carries on the display of the recording file including the waveform. The amplitude and phase calculation of voltage and current, the analysis of protective action characteristics, and so on. The data management system uses file management technology to manage the source files and the analysis result files. The data analysis function includes basic analysis function and advanced analysis function. The basic analysis function includes two parts: one is waveform display, which shows the sampling value of every channel in the recording document directly, so as to obtain the fault occurrence time, the fault maintenance time, the fault removal time, the judgment fault occurrence phase and so on; The second is to extract the basic electrical quantities of a fixed period of time from the data file, such as the amplitude and phase of the fundamental wave of voltage and current and the harmonics of each order, etc. By moving the left and right cursors to realize the passage of the data window, we can get the values of these electrical quantities changing with time. It provides the basis for power system fault analysis. Advanced features include range protection action characteristics analysis and longitudinal protection action characteristics analysis. The range protection action characteristic analysis function obtains the measured impedance value with time and the impedance action characteristic according to the fault recording file. The analysis of the action characteristics of the longitudinal protection includes the characteristic analysis of the directional longitudinal protection and the characteristic analysis of the differential protection of the longitudinal current. By calculating the phase of the power directional element and the differential current, the protective action characteristics of the braking current are obtained, respectively. It provides the basis for the analysis of protective action. The above functions are developed on the mixed platform of vs2008 and Qt4.3.0 with VC development language, and the basic analysis function and the advanced analysis function are tested under the Windows operating system by field test and laboratory test respectively. The test results show that the system can make full and effective use of fault recording data and can reproduce the process of electrical quantity change in fault and abnormal operation.
