Extra-high voltage converter station protection system panoramic monitoring image reconstruction and transmission method

Abstract

The invention discloses a panoramic monitoring image reconstruction and transmission method for an extra-high voltage converter station protection system, belongs to the technical field of panoramic monitoring of extra-high voltage converter stations, and solves the problems that the panoramic monitoring image of the conventional extra-high voltage converter station protection system is blurred and low in resolution, and the panoramic monitoring data transmission is congested when a network fails. Multi-scale convolution blocks are adopted in a deep multi-scale residual network model to construct low-order and high-order features of a multi-scale extraction image, the phenomenon of incomplete extraction of image details is avoided, a residual learning mechanism is adopted to reserve low-order rough features and promote reuse of the features, and then the reconstruction capability of the image is improved; according to the topological optimization, a topological structure of a heterogeneous network is constructed, a framework combining deep reinforcement learning and Monte Carlo tree search is adopted, and the network is sequentially constructed according to a predefined topological rule; the search result of the Monte Carlo tree enhances the learning of the deep convolutional neural network, so that more accurate prediction can be obtained in the next iteration.

Description

technical field [0001] The invention belongs to the technical field of panoramic monitoring of UHV converter stations, and relates to a method for reconstructing and transmitting panoramic monitoring images of a protection system of UHV converter stations. Background technique [0002] With the development of the power grid, the interconnection scale of the power grid is continuously increasing, and the electrical connection within the network is closer. The safe and reliable operation of the UHV converter station plays an important role in the safe and stable operation of the power grid. Therefore, in the daily operation and maintenance of UHV, manual inspection and troubleshooting of equipment failures are required to ensure the safety and stability of the system. . However, this manual inspection mode has high work intensity, and the inspection performance is easily affected by the experience and responsibility of personnel. In order to improve the efficiency of the ope...
