Abstract

The invention discloses a high-voltage direct-current transmission valve cooling system's working condition prediction and fault heads-up platform, comprising: a data processing module and a data exchange module in signal interconnection with the data processing module. The data exchange module is further connected with a teaching staff working module used for teaching, a learner training module used for learning, a printing module used for printing results, and a simulation mechanism used for simulating data. According to the invention, on the basis of the historical running data and the defect conditions and in combination of the actual running data analysis, the working conditions are predicted and fault heads-up research becomes possible so as to provide reference for routine maintenance. At the same time, through the establishment of a simulated training platform similar to an actual converter valve cooling system, the client training requirement can be simulated in a true manner and the full-life cycle of various components can be managed so as to reduce the occurrence of fault and to speed up the fault processing.

Description

technical field [0001] The invention relates to the technical field of converter station equipment, in particular to a working condition prediction and fault early warning platform for a high-voltage direct current transmission valve cooling system. Background technique [0002] The converter valve is the core equipment of the converter station. In the converter station currently in operation, the maximum rated current of the converter valve has reached 5000A. During normal operation, large current passes through the converter valve to generate a lot of heat. In order to prevent the converter valve from being damaged due to excessive temperature, a valve cooling system needs to be configured to cool it. Therefore, the safety and reliability of the converter valve cooling system will directly affect the safety and stability of the DC transmission system. [0003] According to the statistical data of single and double pole blocking of DC converter stations of the State Grid C...
