【摘要】：在對電網(wǎng)調(diào)度監(jiān)控過程中,調(diào)度人員需要長時(shí)間對大量的調(diào)度實(shí)時(shí)數(shù)據(jù)監(jiān)測,由于長時(shí)間監(jiān)測大量的調(diào)度數(shù)據(jù),會(huì)導(dǎo)致調(diào)度人員在視覺上的疲勞,對電網(wǎng)調(diào)度數(shù)據(jù)的敏感度大大降低,從而弱化了對電網(wǎng)運(yùn)行狀態(tài)的全面掌控能力。在傳統(tǒng)的電力調(diào)度軟件系統(tǒng)中,對數(shù)據(jù)結(jié)果會(huì)采用表格和圖形化的方式給調(diào)度人員呈現(xiàn)數(shù)據(jù),但這種數(shù)據(jù)推送方式缺乏概括性,也沒有提示性,從而導(dǎo)致數(shù)據(jù)可閱讀性差,不能提高電網(wǎng)調(diào)度監(jiān)控人員的信息敏感度。宜賓電網(wǎng)可視化分析預(yù)警系統(tǒng)是一套自動(dòng)化的的分析預(yù)警系統(tǒng),系統(tǒng)采用C++語言開發(fā),數(shù)據(jù)采用SQL Server。通過建立自動(dòng)預(yù)警模型,根據(jù)可視化預(yù)警分析算法,由系統(tǒng)自主運(yùn)行的一套電網(wǎng)可視化分析預(yù)警系統(tǒng)。該系統(tǒng)具有使用電網(wǎng)多維度分析的特點(diǎn),具備全面的電網(wǎng)運(yùn)行預(yù)警分析和輔助決策功能。該系統(tǒng)將原來EMS系統(tǒng)靜態(tài)分析監(jiān)測提升到動(dòng)態(tài)分析預(yù)警。將系統(tǒng)的關(guān)注重點(diǎn)由原來的運(yùn)行狀態(tài)監(jiān)控轉(zhuǎn)移到數(shù)據(jù)的綜合分析和預(yù)警決策上。通過該系統(tǒng)的實(shí)施,建設(shè)一套電網(wǎng)運(yùn)行預(yù)警機(jī)制,提供數(shù)據(jù)快速、準(zhǔn)確分析和結(jié)果展示的平臺系統(tǒng),為今后電網(wǎng)調(diào)度策略的提升、調(diào)度數(shù)據(jù)的挖掘和數(shù)據(jù)的展示提供新的模式。宜賓電網(wǎng)可視化分析預(yù)警系統(tǒng)采用電力系統(tǒng)運(yùn)行狀態(tài)分層機(jī)制,根據(jù)運(yùn)行過程中運(yùn)行人員對數(shù)據(jù)的關(guān)注程度和對調(diào)度監(jiān)控的重要性用分層次方式加以區(qū)分,給運(yùn)行人員推送必要的、可靠、關(guān)鍵的信息,再根據(jù)實(shí)際運(yùn)行監(jiān)測的需要用直觀的圖形、帶告警分級的方式為運(yùn)行人員提供數(shù)據(jù)。在第一級顯示界面顯示系統(tǒng)的整體運(yùn)行狀態(tài),在整體運(yùn)行界面上只顯示少量的重要監(jiān)控信息,當(dāng)系統(tǒng)進(jìn)入告警狀態(tài),系統(tǒng)立即啟動(dòng)圖形化報(bào)警。系統(tǒng)的告警機(jī)制采用分級報(bào)警,即事先預(yù)設(shè)各種不同的告警級別,告警級別可以采用不同的顏色配置,如黃色是普通告警、紅色是重要告警,顏色越深告警級別越高;在第二級顯示界面展示運(yùn)行人員關(guān)注的數(shù)據(jù)分析結(jié)果,這種數(shù)據(jù)分析是宏觀的數(shù)據(jù)分析,數(shù)據(jù)可以通過三維圖形化的方式展示一個(gè)或多個(gè)斷面潮流。在宏觀數(shù)據(jù)處理正常狀態(tài)下,系統(tǒng)利用圖形化界面展示與狀態(tài)異常的距離的距離,反之,如果宏觀數(shù)據(jù)處理異常狀態(tài),系統(tǒng)通過分析給出排除異常的對策供運(yùn)行人員參考;第三級界面則展示監(jiān)測信息的具體數(shù)值,其展示方式同樣是采用可視化的圖形界面。
[Abstract]:In the monitoring process of power grid dispatching, the dispatcher needs a long time to monitor a lot of real-time data of dispatch, because of monitoring a large amount of dispatch data for a long time, it will lead to the visual fatigue of dispatcher. The sensitivity of dispatching data is greatly reduced, which weakens the ability to control the operation state of power grid. In the traditional electric power dispatching software system, the data result will be presented to the dispatcher by tabular and graphical methods, but the data push method lacks generality and promptness, which leads to poor readability of the data. Can not improve the information sensitivity of power grid dispatch monitor personnel. The visual analysis and early warning system of Yibin Power Grid is an automatic analysis and early warning system. The system is developed by C language and the data is developed by SQL Server. By establishing an automatic early warning model and according to the visual early warning analysis algorithm, a set of visual analysis and early warning system for power network is established. The system has the characteristics of using multi-dimensional analysis of power grid, and has the function of comprehensive early warning analysis and auxiliary decision making of power grid operation. The system will be the original EMS system static analysis monitoring to dynamic analysis and early warning. The focus of the system is transferred from the original operation state monitoring to the comprehensive data analysis and early warning decision. Through the implementation of the system, a set of early warning mechanism for power grid operation is built, which provides a platform system for fast, accurate analysis and display of data, and provides a new model for the future promotion of power grid dispatching strategy, the mining of dispatching data and the display of data. Based on the hierarchical mechanism of the operation state of the power system in Yibin Power Grid, according to the attention degree of the operators to the data and the importance of the dispatching and monitoring in the operation process, the system is classified in a hierarchical manner. The necessary, reliable and key information is given to the operator, and the data is provided to the operator by visual graphics and alarm grading according to the actual operation monitoring needs. In the first stage, the whole running state of the system is displayed on the interface, and only a small amount of important monitoring information is displayed on the whole running interface. When the system enters the alarm state, the system immediately starts the graphical alarm. The alarm mechanism of the system adopts hierarchical alarm, that is, different alarm levels are preset in advance, and the alarm levels can be configured in different colors. For example, yellow is an ordinary alarm, red is an important alarm, and the darker the color is, the higher the alarm level is. In the second level display interface, the data analysis results of operator's concern are displayed. The data analysis is macro data analysis, and the data can display one or more cross-section power flow through three-dimensional graphic way. In the normal state of macro-data processing, the system uses graphical interface to show the distance between abnormal state and abnormal state. On the contrary, if the macro-data processing abnormal state, the system gives the countermeasure of eliminating abnormal state through analysis for the reference of operators. The third interface displays the specific values of the monitoring information, and the visualization graphical interface is also used.
