Based on power supply industry characteristics, the safety assessment index system of power grid enterprises is improved to be more overall and objective in this paper. Then a comprehensive assessment model is introduced which adopts the trapezium-cloud model to get concept partition of the safety instead of the hard division method in previous studies. The concepts gained by this way can reflect the characteristics of data distribution more obviously. Then according to backward cloud generator, the authors can obtain the cloud parameters, which are used for evaluation of safety.
