Abstract
High Voltage Direct Current Transmission (HVDC), known as a future energy "highway", plays a key role in the history of electric power system development. In this paper, the present status and future prospect of HVDC convertor valves cooling system in china is analyzed. The performance of HVDC convertor valve cooling system is affected by dry, high temperature, cool weather and sand. Air cooling system is referred to be the most suitable outside cooling system of convertor valve in water scarce areas due to its many advantages such as the antifreezing ability, sand prevention and zero emission of sewage. A hybrid cooling system for cool storage system combined with air cooling system was presented. The experimental result shows this system can be used in desert area like Hami area etc.
