The intelligent evaluation method of the substation simulation training system based on composite elements technology is presented aiming at the situation of the lack of perfect and objective evaluation methods for substation simulation training system.The skill of equipment inspection
switching operation and accident handling is decomposed to all kinds of elements and integrated according to inner logic relation.The intelligent evaluation system is realized by quantitative scores and consideration in additional requirement such as time and safety etc.The evaluation method is more objective and reasonable in the intelligent evaluation system.
