Pre-evaluation method for comprehensive technical level of power grid engineering project

The invention discloses a pre-evaluation method for the comprehensive technical level of a power grid engineering project, and belongs to the technical field of power systems. The method comprises the following steps of 1, refining a first-level index into a second-level index to form a comprehensive technical level pre-evaluation index system, and collecting index value sample data of the second-level index; 2, determining the weight of a pre-evaluation index for determining the comprehensive technical level of the power grid engineering project according to the subjective and objective factors and the mutual influence degree between the indexes; 3, determining an evaluation standard of each secondary index, and carrying out quantitative advantage and disadvantage judgment on the collected index value sample data; and 4, correspondingly multiplying the second-level index score by the weight result, and accumulating to obtain a quantitative first-level index technical level pre-evaluation value and a quantita
