The substation in a power plant is a step-up substation, which boosts the electric energy generated by the generator and feeds it into the high-voltage power grid. Substation operation and maintenance is a complex and important process, which covers patrol inspections, equipment maintenance and overhaul, operation management and operation, safety management and other aspects of work. Among them, the patrol inspection of the substation is that the on-duty personnel observe the appearance of the equipment for any abnormalities through regular patrols, such as color changes, debris, whether the needle indication is normal, whether the sound of the equipment is normal, whether there is any abnormal smell, whether the temperature of the equipment that can be touched is normal, and measure the changes in the operating parameters of the electrical equipment during operation, etc., to determine whether the operating status of the equipment is normal. In the prior art, the inspection process is usually carried out through regular inspections by on-duty personnel to understand the equipment operating status, grasp operating abnormalities, and take corresponding measures in a timely manner, which is of great significance for reducing the occurrence of accidents and their impact range; to this end, the substation should formulate specific inspection methods based on the actual working conditions of the operating equipment and summarize the lessons learned from previous handling of equipment accidents, obstacles and defects; but in large cities or industrial areas, with the continuous expansion of the scale of the power grid, the demand for electricity has increased, and multiple substations are required to be distributed in different areas to ensure the stable supply and distribution of electricity; which leads to high pressure and many tasks in equipment operation and maintenance, thereby greatly increasing manpower and material resources during the inspection process, resulting in the inability to fully cover the inspection substations, and thus the inability to timely discover abnormal equipment operation conditions; therefore, to solve the above problems, the present invention provides a remote safety management method and system for substation operation and maintenance.
