Background
The strong smart grid construction requirement is increasingly urgent, and how to accelerate the realization of the strong smart grid is an important subject to which people face. At present, information technology, automation technology and big data technology are highly developed, good technical conditions are provided for power grid intellectualization, and all scientific research departments of a power grid system promote strong smart power grids to develop in different ways. On the other hand, it is to be clearly seen that although the intellectualization of the power grid in terms of operation management is continuously improved, accurate, comprehensive and instant online monitoring of the power transmission line is always established on the basis of the traditional sensors and the traditional power supply stacking, and the improvement in the technical essence is not achieved.
Elements which mainly need to be monitored in the field of power transmission include but are not limited to insulators and mechanical elements.
The insulator of the transmission line insulates the live line from the tower, realizes aerial erection of the high-voltage transmission line, and is an essential device in stable operation of the line. In order to enhance the reliability of the smart grid and enable the smart grid to be more stable, safer and more economic to operate, the insulator needs to be operated and maintained, so that the good insulating property of the smart grid is ensured, and once the old insulator is not updated and maintained in time due to various factors, the electric gap breakdown between a line and a tower is likely to happen under certain adverse meteorological conditions, so that an uncontrollable grid and personal accidents are caused. Therefore, it is necessary to perform online monitoring on the performance of the insulator of the power transmission line, find the hidden operating trouble of the insulator in time, and remind the operation and maintenance staff to replace the insulator.
At present, a means for monitoring the insulator is generally to use a video device to shoot an external phenomenon of the insulator, judge the running state of the insulator through the surface characteristics of the insulator, monitor the insulator through infrared monitoring, and judge the performance of the insulator through the infrared performance of the insulator.
In addition, the ground wire of the power transmission line is a blood vessel of power grid transmission and is a main carrier of power transmission, the safe operation of the wire is related to the stability of the power transmission of the whole power grid, the ground wire can protect the wire from lightning stroke, and the ground wire also plays an important role in power grid communication. In addition, the ground wire is the most problematic line device under natural conditions of wind, sunshine and rain all the year round. For example, icing easily occurs in the weather of a college in winter, so that the ground wire is disconnected, and the power transmission of the peripheral area is influenced; the waving easily occurs under the condition of strong wind, the interphase discharge occurs when the interphase conductor waves, and the abnormal operation state occurs, so that the interphase discharge is required to be discovered and processed as soon as possible; under the long-time operation, the conductor in the ground wire has local strand breakage, becomes the weak point that the electric wire netting is not uniform to discover, influences the reliable and stable nature of whole system. Accidents such as this are numerous and are not listed here. Therefore, the accurate online monitoring on the ground wire is refined, and the abnormity is timely found and processed, so that the necessary condition for ensuring the stable operation of the line is provided.
In addition, how to effectively monitor the mechanical mechanics of the tower foundation of the overhead transmission line is also included.
In summary, from the practical significance, a reasonable and effective overhead transmission line ground wire monitoring and analyzing method has not been provided in the aspect of online detection of overhead transmission lines and cable lines, especially extra-high voltage, extra-high voltage and power grid main structures.
