【摘要】：在对电网调度监控过程中,调度人员需要长时间对大量的调度实时数据监测,由于长时间监测大量的调度数据,会导致调度人员在视觉上的疲劳,对电网调度数据的敏感度大大降低,从而弱化了对电网运行状态的全面掌控能力。在传统的电力调度软件系统中,对数据结果会采用表格和图形化的方式给调度人员呈现数据,但这种数据推送方式缺乏概括性,也没有提示性,从而导致数据可阅读性差,不能提高电网调度监控人员的信息敏感度。宜宾电网可视化分析预警系统是一套自动化的的分析预警系统,系统采用C++语言开发,数据采用SQL Server。通过建立自动预警模型,根据可视化预警分析算法,由系统自主运行的一套电网可视化分析预警系统。该系统具有使用电网多维度分析的特点,具备全面的电网运行预警分析和辅助决策功能。该系统将原来EMS系统静态分析监测提升到动态分析预警。将系统的关注重点由原来的运行状态监控转移到数据的综合分析和预警决策上。通过该系统的实施,建设一套电网运行预警机制,提供数据快速、准确分析和结果展示的平台系统,为今后电网调度策略的提升、调度数据的挖掘和数据的展示提供新的模式。宜宾电网可视化分析预警系统采用电力系统运行状态分层机制,根据运行过程中运行人员对数据的关注程度和对调度监控的重要性用分层次方式加以区分,给运行人员推送必要的、可靠、关键的信息,再根据实际运行监测的需要用直观的图形、带告警分级的方式为运行人员提供数据。在第一级显示界面显示系统的整体运行状态,在整体运行界面上只显示少量的重要监控信息,当系统进入告警状态,系统立即启动图形化报警。系统的告警机制采用分级报警,即事先预设各种不同的告警级别,告警级别可以采用不同的颜色配置,如黄色是普通告警、红色是重要告警,颜色越深告警级别越高;在第二级显示界面展示运行人员关注的数据分析结果,这种数据分析是宏观的数据分析,数据可以通过三维图形化的方式展示一个或多个断面潮流。在宏观数据处理正常状态下,系统利用图形化界面展示与状态异常的距离的距离,反之,如果宏观数据处理异常状态,系统通过分析给出排除异常的对策供运行人员参考;第三级界面则展示监测信息的具体数值,其展示方式同样是采用可视化的图形界面。
[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.
