一种智能变电站告警信息上送方法，在变电站监控系统中为间隔对象增加数据质量位属性，通过改变数据质量位的值来标记间隔对象是否处于检修状态；告警直传模块在间隔有告警信号产生而组织告警直传文本信息前，先查找到产生告警信号的间隔对象，根据其数据质量位的值来判断该间隔对象是否处于检修状态，若判断结果为否，则组织告警直传的文本信息，并转发给调度主站；若判断结果为是，则不组织告警直传的文本信息。A method for sending alarm information in smart substations. In the substation monitoring system, the data quality bit attribute is added to the interval object, and the value of the data quality bit is changed to mark whether the interval object is in the maintenance state; the alarm direct transmission module generates an alarm signal in the interval Before organizing alarm direct transmission text information, first find the interval object that generates the alarm signal, and judge whether the interval object is in the maintenance state according to the value of its data quality bit, if the judgment result is no, then organize the text information of alarm direct transmission , and forward it to the dispatching master station; if the judgment result is yes, the text information of the alarm direct transmission will not be organized.
在变电站监控系统中还为间隔对象增加检修标志牌属性以及检修标志牌图元，所述检修标志牌属性、检修标志牌图元与数据质量位属性相互关联，当间隔对象处于检修状态时，通过修改检修标志牌属性的值使数据质量位标记为检修状态，同时使检修标志牌图元在间隔监控画面上对应的间隔对象一侧显现。In the substation monitoring system, the maintenance signboard attribute and the maintenance signboard graphic element are also added for the interval object. The maintenance signboard attribute, the maintenance signboard graphic element and the data quality bit attribute are interrelated. When the interval object is in the maintenance state, through Modify the value of the maintenance signboard attribute to mark the data quality bit as the maintenance status, and at the same time make the maintenance signboard graphic element appear on the side of the corresponding interval object on the interval monitoring screen.
本发明与现有技术相比的优点在于：The advantage of the present invention compared with prior art is:
变电站端在将告警直传信息上送调度中心告警信息前进行预处理，通过监控后台置检修屏蔽告警直传信息等技术，避免由正在进行检修的间隔所产生的伪告警信息上送调度中心，降低对值班人员的干扰，切实提高工作效率。The substation side performs pre-processing before sending the alarm direct transmission information to the dispatching center, and uses technologies such as monitoring and maintenance to shield the direct transmission of alarm information to avoid sending false alarm information generated by the maintenance interval to the dispatching center. Reduce the interference to the staff on duty and effectively improve work efficiency.

如图1所示的一种智能变电站告警信息上送方法，在变电站监控系统中为间隔对象增加数据质量位属性、检修标志牌属性以及检修标志牌图元，所述检修标志牌属性、检修标志牌图元与数据质量位属性相互关联，当间隔对象处于检修状态时，通过修改检修标志牌属性的值使数据质量位标记为检修状态，同时使检修标志牌图元在间隔监控画面上对应的间隔对象一侧显现；告警直传模块在间隔有告警信号产生而组织告警直传文本信息前，先查找到产生告警信号的间隔对象，根据其数据质量位的值来判断该间隔对象是否处于检修状态，若判断结果为否，则组织告警直传的文本信息，并转发给调度主站；若判断结果为是，则不组织告警直传的文本信息。A kind of intelligent substation alarm information sending method as shown in Figure 1, in the substation monitoring system, add data quality bit attribute, maintenance signboard attribute and maintenance signboard graphic element for interval object, described maintenance signboard attribute, maintenance sign The card graphic element and the data quality bit attribute are interrelated. When the interval object is in the inspection state, the data quality bit is marked as the inspection status by modifying the value of the inspection sign attribute. One side of the interval object appears; the alarm direct transmission module first finds the interval object that generates the alarm signal before the alarm signal is generated in the interval and organizes the alarm direct transmission text information, and judges whether the interval object is in maintenance according to the value of its data quality bit status, if the judgment result is no, organize the text information of the direct transmission of the alarm and forward it to the dispatching master station; if the judgment result is yes, then do not organize the text information of the direct transmission of the alarm.
如图2所示，为了实现告警直传功能，需要在调度端部署告警直传信息的采集功能模块，在厂站端部署告警直传服务和告警信息转发功能模块，并在告警直传服务前增加前置规约采集数据的智能预处理服务，在组织告警直传信息前先对前置采集的信号进行智能预处理，过滤掉一些伪告警，有效减少伪告警上送调度的条目数；告警图形网关采用DL476协议的字符串数据块分别与厂站监控系统和调度端进行告警信息传输；厂站监控系统先将变电站SCADA系统智能处理过的告警信息转换为带站名和设备名的标准告警信息，传输给调度端，调度端告警采集程序与厂站监控系统建立TCP连接，接收告警信息，并以消息的方式发送给告警系统。As shown in Figure 2, in order to realize the alarm direct transmission function, it is necessary to deploy the alarm direct transmission information collection function module at the dispatching end, and deploy the alarm direct transmission service and alarm information forwarding function modules at the factory station side, and Increase the intelligent preprocessing service of the data collected by the front-end protocol. Before organizing the direct transmission of the alarm information, the pre-collected signal is intelligently pre-processed to filter out some false alarms and effectively reduce the number of items sent to the scheduling of false alarms; alarm graphics The gateway adopts the string data blocks of the DL476 protocol to transmit alarm information with the plant monitoring system and the dispatching terminal respectively; the plant monitoring system first converts the alarm information intelligently processed by the substation SCADA system into standard alarm information with station names and equipment names, The alarm collection program of the dispatching end establishes a TCP connection with the plant monitoring system, receives the alarm information, and sends it to the alarm system in the form of a message.
