【摘要】：電能質(zhì)量監(jiān)測(cè)分析在中國(guó)已有二十多年的發(fā)展歷史,但在電力市場(chǎng)上仍處于培育和起步階段。早期不同廠家電能質(zhì)量監(jiān)測(cè)數(shù)據(jù)的格式規(guī)約各異,不利于電能質(zhì)量數(shù)據(jù)的共享與交換。為了使電能質(zhì)量數(shù)據(jù)的共享、分析與評(píng)估成為可能,IEEE提出了一種統(tǒng)一的電能質(zhì)量數(shù)據(jù)交換格式——PQDIF標(biāo)準(zhǔn),該格式采用二進(jìn)制結(jié)構(gòu),具有良好的數(shù)據(jù)壓縮性,但由于文件內(nèi)部的通道定義和序列值分離,兩者間采用較為復(fù)雜的參數(shù)索引方式相關(guān)聯(lián),需要借助第三方軟件或是自主研發(fā)的解析軟件才能完成對(duì)PQDIF的解析,且難以實(shí)現(xiàn)基于Web的數(shù)據(jù)傳輸和交互。本文采用面向?qū)ο蟮慕＜夹g(shù),基于IEEEP1159.3(Drm 11)標(biāo)準(zhǔn)和擾動(dòng)分類,將電能質(zhì)量監(jiān)測(cè)數(shù)據(jù)分為V類、W類和P類三種類型,在邏輯結(jié)構(gòu)上把數(shù)據(jù)源中的通道記錄和實(shí)際觀測(cè)記錄緊密相連,使其便于修改和解析：基于可擴(kuò)展標(biāo)記語(yǔ)言XML,提出了一種用XML文件存儲(chǔ)實(shí)現(xiàn)的電能質(zhì)量數(shù)據(jù)格式模型PQXML,明確規(guī)定了模型的結(jié)構(gòu)并約定了詳細(xì)的語(yǔ)義,建立了UML類圖,給出類圖與XML文檔間的模式映射規(guī)則,極大地提高了數(shù)據(jù)模型的通用性,易于跨平臺(tái)傳輸及異構(gòu)系統(tǒng)間的交換；最后,采用PQXML標(biāo)準(zhǔn)規(guī)定了電能質(zhì)量監(jiān)測(cè)主站系統(tǒng)與不同廠家的電能質(zhì)量子系統(tǒng)之間的數(shù)據(jù)交互要求,并提出一致性檢測(cè)方法,以便將來(lái)為上層的電能質(zhì)量高級(jí)應(yīng)用軟件提供更好的服務(wù)。使用本文的建模方法,使得電能質(zhì)量數(shù)據(jù)交換模型及其實(shí)現(xiàn)方式具有良好的魯棒性和可行性,通過與IEEE PQDIF進(jìn)行解析性能比較,證明了PQXML模型具有更好的傳輸性、易用性和跨平臺(tái)特性,從而促進(jìn)智能電網(wǎng)及能源互聯(lián)從理論到應(yīng)用的進(jìn)一步發(fā)展。
[Abstract]:Power quality monitoring and analysis has been developing for more than 20 years in China, but it is still in the developing and starting stage in the power market. In the early years, the format of power quality monitoring data from different manufacturers is different, which is not conducive to the sharing and exchange of power quality data. In order to make power quality data sharing and analysis and evaluation possible, IEEE proposed a unified power quality data exchange format, PQDIF standard, which adopts binary structure and has good data compression. However, because of the separation of channel definition and sequence value within the file, the two methods are related by a more complex parameter index method, which requires the help of third-party software or self-developed parsing software to complete the parsing of PQDIF. And it is difficult to realize data transmission and interaction based on Web. Based on IEEEP1159.3 (Drm 11) standard and disturbance classification, the power quality monitoring data are classified into three types: class V, class W and class P, based on object-oriented modeling technology. In the logical structure, the channel records in the data source and the actual observation records are closely connected to make it easy to modify and analyze. Based on extensible markup language (XML,), a power quality data format model PQXML, based on XML file storage is proposed. The structure of the model is clearly defined and the detailed semantics are agreed, the UML class diagram is established, and the schema mapping rules between the class diagram and the XML document are given, which greatly improve the generality of the data model and facilitate the cross-platform transmission and the exchange between heterogeneous systems. Finally, the data interaction requirements between the power quality monitoring master station system and the power quality subsystem of different manufacturers are defined by PQXML standard, and the consistency detection method is proposed. In order to provide better service for the power quality application software in the future. The modeling method of this paper is used to make the power quality data exchange model and its implementation have good robustness and feasibility. Compared with the analytical performance of IEEE PQDIF, it is proved that the PQXML model has better transmission performance. Ease of use and cross-platform characteristics promote the further development of smart grid and energy interconnection from theory to application.
