Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
It should be noted that the terms "upper", "lower", "left", "right", "front", "back", etc. used in the present invention are for clarity of description only, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not limited by the technical contents of the essential changes.
With reference to fig. 1, the present invention provides a source network load control second-level network remote monitoring and analyzing platform, which includes a network device management system, a data acquisition server, a network monitoring system, and an early warning and analyzing system.
The network equipment management system is used for creating and managing a network equipment database contained in all substations in an area, wherein the network equipment database comprises the numbers and types of all network equipment and the numbers and the hierarchies of the substations.
The network equipment comprises a monitoring unit and a monitoring host which are arranged in the transformer substation, and a plurality of data acquisition servers which are arranged in one-to-one correspondence with the transformer substation level; the monitoring host is connected with the monitoring unit and used for receiving the transformer substation operation data acquired by the monitoring unit and the operation data of the next-stage transformer substation connected with the transformer substation. To simplify the structure, the substations here can be hierarchically arranged according to the network characteristics of the transmission circuit, and the hierarchy of the substations is arranged according to the node hierarchy of the substations in the transmission network, because substations at the same level are usually configured the same or similar, which facilitates subsequent analog monitoring analysis. When a new transformer substation is introduced, the effective capacity expansion of the monitoring network can be realized by directly adding corresponding monitoring nodes in the monitoring network.
Preferably, the substation operation data includes network device operation data, network device operation and maintenance information, and substation operation and maintenance information. The network equipment operation data is used for reflecting the current working state of the network equipment, the operation and maintenance information of the network equipment indirectly influences the data acquisition work of the relevant equipment of the transformer substation, and the operation and maintenance information of the transformer substation possibly influences the data acquisition work of a plurality of network equipment and even the network equipment of other transformer substations. The network equipment operation data is used for directly judging whether the network equipment is abnormal, and the network equipment operation and maintenance information and the transformer substation operation and maintenance information are used for judging whether the network equipment is abnormal in a side-assisted manner.
More preferably, the substation operation data further includes communication quality data, and the communication quality data is introduced here for two reasons: firstly, the communication quality data can relate to the transmission frequency of the operation data, which is easy to affect the abnormal judgment of the monitoring unit or the monitoring host, and secondly, when the communication quality is poor, the judgment is easy to miss due to untimely transmission of the key data.
The data acquisition server is used for acquiring the operation data of the transformer substation to which the monitoring hosts of all the transformer substations in the current hierarchy receive and the corresponding operation data of the next-stage transformer substation in real time/periodically; the network monitoring system is connected with the data acquisition server, and monitors and analyzes the operation data of each transformer substation by combining the corresponding operation data of the next-level transformer substation and the configuration data of each network device according to the sequence of the levels from low to high, and searches the abnormal network devices.
Preferably, the network monitoring system synchronously refers to the relationship between the network device to be analyzed and other network devices, and analyzes the network device to be analyzed by combining the operation data of the related network devices. For example, a voltage monitoring unit is arranged on an output loop of the substation a, the output loops are respectively connected to the substations a1, a2 and A3, and at this time, the sum of the voltages of the input loops of the substations a1, a2 and A3 can be combined to determine whether the voltage monitoring unit corresponding to the output loop of the substation a is abnormal. It should be understood that the foregoing examples are only for better understanding that the present invention assists in analyzing whether the network device is abnormal or not by means of the relationship between the network devices, and in practical applications, this process is more complicated, and it is necessary to perform data abnormality judgment and supplementary analysis of missing data by combining the relationships between multiple network devices in the same hierarchy and the next hierarchy.
And the early warning analysis system performs early warning analysis on the front-stage network equipment and the rear-stage network equipment of the abnormal network equipment according to the monitoring analysis result of the network monitoring system and by combining the hierarchical relationship between the transformer substations. In the actual operation process, when one network device is abnormal, a large amount of alarm information sent by the related network device is easily received in a short time, namely, faults are easily grouped and the devices have relevance, and how to extract key alarm information from the alarm information, even the devices with the key faults are quickly found according to the current network device is crucial to optimize alarm information and improve troubleshooting efficiency. Therefore, due to the hierarchical relationship among the network devices, when it is determined that one of the network devices is abnormal, the most important concern is the working state of the other network devices related to the one network device, and the early warning analysis system is based on the point, focuses on the related network devices, and performs targeted analysis on the related network devices, so as to effectively improve the failure early warning analysis and troubleshooting efficiency.
Preferably, the network monitoring system improves the monitoring priority of the network device which may have abnormality according to the early warning analysis result fed back by the early warning analysis system, for example, improves the data acquisition frequency, and further improves the failure early warning efficiency.
In some examples, the monitoring analysis platform further comprises a fault handling system. Based on the characteristic that the faults appear in groups and the devices have relevance, the fault processing system receives abnormal network device information sent by the network monitoring system and the early warning analysis result made by the early warning analysis system for the abnormal network devices, divides fault areas by combining fault levels and network device relevance, analyzes fault reasons for each fault area, generates a corresponding fault removing scheme, and sends the fault removing scheme together with the abnormal network device numbers and the fault reasons to the monitoring terminal. By the mode, the problem that one fault is solved and the other fault is solved and the fault is not solved completely is solved. In addition, after the fault area is divided, key fault points can be found quickly according to the characteristics of the fault area, and the fault removal efficiency is improved.
In other examples, the monitoring and analyzing platform further includes a visualization system, configured to perform diagrammatizing processing on a monitoring and analyzing result of the network monitoring system and an early warning and analyzing result of the early warning and analyzing system, and provide visualization functions of user data display and system state browsing. The visualization system can convert the collected data structures in various formats into visual graphs or image information, and a user can custom display views according to own monitoring requirements, so that monitoring personnel can conveniently observe the images, and the monitoring burden is reduced.
The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may be made by those skilled in the art without departing from the principle of the invention.
