Abstract
A method and apparatus for managing icing of a plurality of transmission lines in a power transmission system. A power transmission system comprises a plurality of transmission lines and a control system. A first amount of power flows into the power transmission system through the plurality of transmission lines and a second amount of power flows out of the power transmission system through the plurality of transmission lines. The control system is configured to change a flow of power through the plurality of transmission lines such that icing of the plurality of transmission lines is managed. The first amount of power flowing into the power transmission system and the second amount of power flowing out of the power transmission system remains substantially constant during the change in the flow of power through the plurality of transmission lines.
