The invention provides an electric power emergency repair light source evaluation method based on a grid acquisition method and a maximum information coefficient method. The evaluation method includes following steps: establishing an index system for comprehensive evaluation by employing the grid acquisition method and dividing the system into index hierarchies; calculating each index value, performing standardization processing on the index values, and obtaining dimensionless index data; simplifying the index system by employing the maximum information coefficient method, and screening important index items; for the screened important index items, determining index weights by employing a fuzzy Borda number analytic method; and calculating comprehensive performance evaluation scores of illuminating lamps according to the weights, and determining the to-be-repaired light source according to the comprehensive performance evaluation score. The evaluation method is applicable to the performance evaluation of the illuminating lamps employed in occasions including substations, emergency repair vehicles, and high-voltage circuit towers etc. in an emergency repair system, and the most appropriate illuminating equipment can be selected according to the special requirements of the illuminating equipment in the emergency repair system.
