Provided are an extra-valve cooling system for a direct current converter valve and operating method thereof. The system comprises a main pump, an air cooler and a closed cooling tower; the main pump, the air cooler and the closed cooling tower are orderly connected in series via a pipeline, and the series pipeline is connected with a converter valve to form a closed loop; a three-way valve is arranged between the air cooler and the closed cooling tower, and the three-way valve is connected with a bypass pipeline in parallel and then connected with the converter valve; the temperature of a cooling medium in the loop can be decreased to reach a preset temperature by adjusting the working state of the air cooler and the working state of the closed cooling tower according to environment temperature change; the extra-valve cooling system for the direct current converter valve has high cooling capacity, excellent environmental adaptability and good energy / water saving performances.
Description
technical field [0001] The invention relates to an external cooling system for a DC converter valve, in particular to a composite multi-climate adaptive external cooling system for a DC converter valve and an operating method thereof. Background technique [0002] As my country's high-voltage direct current transmission technology becomes increasingly mature, the construction of direct current transmission projects is in a golden period of development. In the high-voltage direct current transmission system, the cooling system is an important component of the heat dissipation system of the converter valve, and its operation directly affects the power transmission capacity of the entire direct current system. Therefore, it is particularly important to ensure the stable, reliable and efficient operation of the cooling system. [0003] At present, the external cooling equipment of the converter valve cooling system uses an air cooler or a closed cooling tower to discharge the h...
