With the development of intelligent substation technology,the transition from traditional substation to intelligent substation will continue for a long time.Aiming at the shortcomings of manual maintenance of the remote device model as heavy workload and error-prone,the characteristics of the information structure and object model of the telecontrol device are analyzed.A remote configuration upgrade conversion scheme is proposed.Combined with the specific application examples,the program design and development process of the tool software are introduced,the modules that make up the tool are put forward,and their functions are described in detail.Compared with the traditional way,the scheme can significantly reduce the difficulty of substation remote transformation and improve the efficiency of project implementation.
