Description

Technical Field

[0001] The present invention relates to the technical field of power system safety, and in particular to a system and method for monitoring the icing status of a power transmission line based on online power supply and ultrasonic deicing. Background Art

[0002] With the continuous development of the power system and the increasing scale of transmission lines, icing has become one of the major issues affecting the stability and safety of high-voltage transmission lines. Icing not only significantly increases the mechanical load of transmission lines, causing excessive pressure on conductors and towers, but may even cause fractures and collapses, leading to large-scale power outages and seriously threatening the safe operation of the power grid. In addition, the accumulation of ice layers will also have an adverse effect on the electrical performance of the line, increase the risk of corona discharge, and reduce the transmission capacity and efficiency of the line.

[0003] At present, traditional deicing methods mainly rely on manual inspection, mechanical knocking and ice melting equipment. These methods have many disadvantages: first, manual inspection is not only time-consuming and laborious, but also difficult to achieve real-time monitoring and timely response to ice covering; second, mechanical knocking methods may cause physical damage to wires and towers, affecting their service life; finally, ice melting equipment usually requires an external power supply, which increases the complexity and maintenance cost of the system. At the same time, the stability of the external power supply is difficult to guarantee under extreme weather conditions.

[0004] In particular, the prior art lacks an intelligent system that can monitor the icing status of power transmission lines in real time and automatically start deicing operations. Traditional deicing methods often have lags and are difficult to respond to sudden icing situations in a timely manner, resulting in poor deicing effects and even more serious consequences due to untimely handling.

[0005] In this context, it is particularly important to develop an ultrasonic deicing system for transmission lines based on online power supply and ice status monitoring. The system obtains electrical energy from high-voltage transmission lines through induction coils to achieve dependence on external power supplies, thereby improving the autonomy and operational stability of the system. At the same time, combined with the ice status monitoring module, the system can monitor the ice thickness and status of the conductors in real time, and determine through the control module whether it is necessary to start the ultrasonic deicing module and the thermal ice melting module for deicing operations. The ultrasonic deicing module uses ultrasonic vibrations to peel off the ice layer from the conductor, and has the advantages of non-contact, damage-free, and high efficiency; while the thermal ice melting module heats and melts the ice layer through resistance heating, providing additional deicing means to ensure that the ice layer can be efficiently removed under different icing conditions.

[0006] To sum up, based on the shortcomings of the prior art, the patent of this invention aims to provide a transmission line icing status monitoring and ultrasonic deicing system based on online power supply, so as to solve many problems existing in traditional deicing methods and ensure the safe and stable operation of the power grid.
