Abstract:This paper proposes an application scheme of big data analysis in the management of substation operation and maintenance, analyzes the problems that currently exist between business growth and resource allocations such as human resources and material resources, and actively explored and promoted the role of big data in coordinating resources such as manpower and material resources and business management and control. With the help of Power BI big data analysis software, which constructs a multi-faceted "big data + operation and maintenance" application research system for key factors panoramic display, job management optimization decision, and flexible control of work process based on the data of production management and personnel management, realizes the comprehensive and multi-temporal dynamic display of the key factors of personnel maintenance, personnel, workload and substation, proposes an optimization decision-making method for personnel assessment and production planning based on indicators such as “person-to-station ratio” and “workload forecast”, explores the adjustable relationship between periodicity and aperiodicity, independence and coupling work, and improves the flexibility of the whole process control. The research results have reference significance and application value for comprehensively improving the optimal allocation of resources such as manpower and material resources for transportation inspection and the intelligent level of business processing.
