The invention discloses a direct current power transmission line typhoon risk evaluation method. The direct current power transmission line typhoon risk evaluation method comprises steps that step 1, wind speed v and wind direction data of a direct current power transmission line A point are acquired; step2, the vertical wind speed of the direct current power transmission line A point is calculated; step 3, the maximum bearable wind speed of the line is corrected; step 4, the maximum bearable wind speed of the line is corrected continuously by considering the position of the direct current power transmission line and voltage drop operation; step 5, the value-at-risk of the windage yaw discharge of the line A point is acquired; step 6, the corrected line value-at-risk is acquired by considering the accumulated influences of the typhoon on the line after the last inspection; step 7, the value-at-risk of the line A point is acquired by considering the importance of the direct current power transmission line and the condition of the voltage drop operation; step 8, the final value-at-risk of the direct current power transmission line A point in different operation states is calculated. A risk evaluation result more suitable for actual circumstances is acquired, and a feasible criterion is provided for reasonable working arrangement of power grid workers.
