本发明属于电网调度领域,特别是一种基于智能电网调度系统的变站监控信息自动验收系统。The invention belongs to the field of power grid dispatching, in particular to an automatic inspection and acceptance system for substation monitoring information based on a smart grid dispatching system.
背景技术Background technique
目前,江苏省内变电站已基本实现无人值班,由各级调控中心负责变电站的日常监控。随着经济的发展,电网的建设加快,调控中心除了日常监控外,还要负责新建、改、扩建变电站的监控信息接入调控中心的验收核对。所有变电站监控信息的核对都由监控值班人员和现场调试人员逐一核对,而一个新建站往往有上千个遥信信息、数百个遥测信息,核对工作量很大,特别是同时有多个站需要核对监控信息数据时,需要多个监控值班人员与现场核对信息,在监控人员紧张的现状下,往往造成多个施工单位排队等候验收,拖延设备施工周期,延误了设备投运的时间,限制了运行方式的调整,为电网安全运行埋下了隐患。同时占用了施工运维人员、自动化人员和监控值班人员大量时间和精力,对正常值班工作造成了一定的影响。At present, substations in Jiangsu Province have been basically unattended, and the control centers at all levels are responsible for the daily monitoring of substations. With the development of the economy, the construction of the power grid is speeding up. In addition to daily monitoring, the control center is also responsible for the acceptance and verification of the monitoring information of new, renovated and expanded substations connected to the control center. The checking of all substation monitoring information is checked one by one by the monitoring personnel on duty and on-site commissioning personnel, and a new substation often has thousands of remote signaling information and hundreds of telemetry information, and the checking workload is very heavy, especially when there are multiple stations at the same time. When it is necessary to check the monitoring information data, multiple monitoring personnel on duty are required to check the information with the site. Under the current situation that the monitoring personnel are tense, it often causes multiple construction units to wait in line for acceptance, delaying the equipment construction cycle and delaying the time for equipment to be put into operation. The adjustment of the operation mode has laid a hidden danger for the safe operation of the power grid. At the same time, it takes up a lot of time and energy of construction operation and maintenance personnel, automation personnel and monitoring duty personnel, which has a certain impact on normal duty work.
如图1所示,统人工验收方式由厂站发起,信息流经过厂站测控、总控,途径通信通道等传输,到达主站前置,与主站数据库录入的保护节点表、断路器信息表、刀闸表、接地刀闸表、测点遥信信息表、前置遥测定义表、遥控关系表、前置遥信定义表、遥信定义表、二次遥信定义表等进行关联匹配,触发相应的告警信息、光字牌、接线图中开关和刀闸变位,显示对应间隔位置遥测数值。该信息流过程长,调试过程中发生异常情况频率较高,且异常点难以掌握。单个信息验收通过与否全靠监控人员人工观察、核对,无法排除人为出错的可能,影响验收效率。As shown in Figure 1, the traditional manual acceptance method is initiated by the factory station, and the information flow is transmitted through the factory station measurement and control, general control, and communication channels, etc., to the front of the master station, and the protection node table and circuit breaker information entered in the database of the master station table, knife switch table, grounding knife switch table, measuring point remote signal information table, front telemetry definition table, remote control relationship table, front remote signal definition table, remote signal definition table, secondary remote signal definition table, etc. , trigger the corresponding alarm information, light plate, switch and knife switch displacement in the wiring diagram, and display the telemetry value of the corresponding interval position. The information flow process is long, and abnormal situations occur frequently during the debugging process, and the abnormal points are difficult to grasp. Whether a single information is accepted or not depends on the manual observation and verification of the monitoring personnel, and the possibility of human error cannot be ruled out, which will affect the efficiency of acceptance.
