Optimization for positions of damper on aerial conductors is very important to reduce the severity of aeolian vibration. After analyzing stochastic characteristics of aeolian vibration, the probability distributions of vibration frequencies of transmission lines are obtained according to the relation between wind speed and vibration frequency of aerial conductors. Then, a numerical calculation method about installing positions of dampers on transmission lines by calculating the weighted amplitude ratio is proposed, it can take danger vibration frequency range and probability distribution of vibration frequencies into account. At last, a practical engineering is computed adopting this method, the computation result show that the proposed method is effective. So a new calculation method for optimizing the locations of damper is given.
