Embodiment Construction
[0014] As shown in the figure, the remote comprehensive online monitoring method for electric power automation equipment, the specific steps are as follows:
[0015] (1) The automation equipment in the substation, including RTU device / comprehensive automatic master control machine, power collection device, Secondary security protection equipment access Data network access device;
[0016] (2) Inside the substation Data network access equipment and The backbone data network equipment nodes are connected and finally imported into The core node of the core data network is the dispatching automation master station;
[0017] (3) Pass at the dispatching automation master station The data acquisition and analysis server names and numbers all connected devices to form a huge network topology;
[0018] (4) The data acquisition and analysis server communicates with each device through heartbeat messages to determine whether it is online or dead;
[0019] (5) Store the...

The invention discloses a remote comprehensive online monitoring method for electric power automation devices. By means of the method, online real-time monitoring of the automation devices is achieved, and various power grid losses caused by machine halt of the automation devices are avoided. The method is characterized in that the automation devices in a transformer substation are connected to a data network access device of the transformer substation, wherein the automation devices comprise the RTU device, the integrated automation general control machine, the electric quality acquisition device and the secondary safety protection equipment; the data network access device in the transformer substation is connected with backbone data network device nodes and finally imported to a core data network device node, namely a dispatching automation master station; all the accessed device are named and numbered through the dispatching automation master station to form a network topology; heartbeat messages are sent out by a data collection and analysis server to get in touch with all the devices so as to judge whether the devices are online or crash; the judged results are stored in a history data server database and operating staff are informed through an alarm server in the modes of voice alarm and mobile phone short message alarm.
Description
technical field [0001] The invention relates to a remote comprehensive on-line monitoring method for electric power automation equipment in the power dispatching process. Background technique [0002] At present, the 220kV and 66kV substations of the power system have been unattended, and the monitoring and control of the substations are completely dependent on automation equipment. Whether the planning structure of the automation equipment is reasonable or not, and whether the equipment is running online will directly affect the monitoring and control of the field equipment by the dispatcher. A prefecture-level regulatory department has to monitor hundreds of substations at the same time, all of which must be monitored through automated equipment. [0003] The traditional monitoring system can only monitor the switching and analog quantities of the primary equipment through the automation equipment in the substation, and when the substation automation equipment is shut...
