Power plant DC system DC stage difference cooperation test method

The invention provides a power plant DC system DC stage difference cooperation test method, and belongs to the technical field of intelligent detection. Comprising the following steps: acquiring a test current sequence and an action time sequence of a to-be-detected DC circuit breaker, and carrying out time sequence correlation analysis on the two sequences to obtain a test current-action time time domain correlation characteristic graph; enabling the test current-action time time domain correlation feature map to pass through a local feature explicator based on an adaptive attention module to obtain an adaptive enhanced test current-action time time domain correlation feature map; and determining whether the performance of the to-be-detected DC circuit breaker meets a predetermined standard based on the adaptive reinforcement test current-action time time domain correlation feature map. The judgment result of the performance of the direct-current circuit breaker is high in accuracy. 本发明提供了一种发电厂直流系统直流级差配合试验方法
