“…Due to the remote location or poor environment and other reasons, manual confirmation cannot be carried out at the remote operation site. At present, some stations use image recognition, pressure sensing and other methods to assist in determining the position of the isolation switch, but the above-mentioned position monitoring methods still have many problems in terms of stability, accuracy and adaptability, such as the equipment installation of pressure sensing, deployment and replacement without power failure, and the wear and oxidize of micro switch contacts (Liu et al, 2018;Cai et al, 2017;Teng et al, 2019). Existing methods for monitoring the opening and closing positions of isolation switches have certain limitations (Cheng and Xiang, 2020).…”

To improve the intelligence and automation for adapting to the development of prosumer substations, this paper proposes an isolation switch opening and closing position discrimination method based on intelligent image recognition technology. The marking point recognition and edge detection method based on the Canny algorithm is developed to identify the open and close position of disconnecting switch. Compared with the traditional auxiliary switch contact, the proposed method can form the “double confirmation” criterion of non-homologous position to realize the open and close position of the disconnecting switch, while providing the auxiliary discrimination support for one-button compatible operation. In addition, the transformation scheme of intelligent recognition and monitoring of the disconnecting switch is designed in the high voltage environment of the substation to enhance the adaptation to the prosumer substation. The field work proves that the designed system has good accuracy and reliability, which can enhance the development of one-button sequence control technology and the implementation and application in the construction site.
