Abstract: With the continuous development of the power grid architecture, More and more traditional substations have been replaced by smart substations, As the main force of the power grid production front line, Substation maintenance center undertakes major tasks such as daily maintenance, equipment maintenance, protection and transformation of the power grid, yet, At present, the traditional maintenance workflow still relies more on manual discrimination and manual assistance, With the increase of substations and the increase of operating equipment, Excessive reliance on human labor unions to increase personnel carrying capacity, And easy to cause confusion in work task scheduling, The old maintenance and management mode is no longer applicable, For this case, This paper presents a multi-task intelligent scheduling system based on personnel carrying capacity portrait, By constructing a multi-dimensional intelligent maintenance and management system of "intelligent scheduling + auxiliary monitoring", Realize the intelligent management of task personnel recommendation and automatic task scheduling, improve work efficiency, To solve the situation of narrow traditional maintenance work thinking, difficult scheduling, and low efficiency.
