Method and device for assessing risk of electric power communication network

The invention provides a method for assessing risk of an electric power communication network. The method comprises the following steps: hierarchically analyzing various risk factors, and using risk factors with the same attribute as elements of the same risk factor set; acquiring a quantized value of degree of influence on risk between two risk factor sets; calculating a weight coefficient between the two risk factor sets according to the qualified value; calculating a risk value according to the weight coefficient; and adjusting the corresponding risk factor in the electric power communication network according to the risk value. The invention further provides a device for assessing risk of the electric power communication network. Due to the method and the device for estimating risk of the electric power communication network, the comprehensiveness of risk assessment of the electric power communication network is improved, the reliability of the electric power communication network is enhanced, and the work efficiency is simultaneously improved.
