The invention relates to a power supply
plant performance index evaluating method based on a policy
library. The method comprising the steps that the policy
library of a power supply
plant is constructed according to technical supervision and
countermeasure standards and the actual conditions of the power supply
plant; a regular
work plan, an index regular supervision plan and a real-time supervision plan are generated; the implementation of the regular
work plan, the index regular supervision plan and the real-time supervision plan is supervised to acquire implementation results; the implementation results are collected, and problems are generated according to the implementation results and a preset problem generation rule; the generated problems are classified, and then a problem libraryis generated; based on the problems in the problem
library, the method automatically generates a problem rectification
work plan; and the policy library, the regular work plan, the index regular supervision plan, the real-time supervision plan, the implementation, the implementation results, the problem library, the problem rectification work plan and the rectification of the problems are collected to form a large
database.
