The invention provides a method for conducting intelligent evaluation on a student operation in a training system. The evaluation modes for training students include the running equipment operation evaluation mode, the power grid operation index evaluation mode and the accident pre-arranged planning analysis and evaluation mode. According to the running equipment operation index evaluation mode, whether equipment operated by a student for enabling the system to run meets electrical equipment operation normalization or not and whether the operation of the student is a mistaken operation or not are evaluated. According to the power grid operation index evaluation mode, whether the safety, reliability and economy of power grid operation meet the requiring level set by a teaching plan or not is evaluated. According to the accident pre-arranged planning analysis and evaluation mode, a power grid accident and accident handling mode in the teaching plan are made in advance; after the training is ended, the student physical fault handling mode and the accident pre-arranged planning making handling mode are analyzed and compared, and therefore pre-arranged planning analysis and evaluation for a power grid accident are achieved. The method for conducting intelligent evaluation on the student operation is high in practicability, has quite high flexibility and feasibility, and can effectively improve the evaluation level of the training system.
