The invention relates to the field of distribution automation detection, in particular to a technical performance test platform of a distribution automation device. The technical performance test platform stimulates high voltage power transmission and distribution equipment by aid of low voltage equipment and includes an experimental platform, a controller and a monitoring center. The experimental platform is connected with the controller, and the controller is connected with the monitoring center through optical fibers. The experimental platform includes an analog 10kV distribution line, an analog high voltage transformer substation supply transformer and an analog neutral point device, an analog switch device, an analog voltage transformer, an analog current transformer, an analog distribution transformer and an analog grounding control unit. The a technical performance test platform integrates the experimental platform, the controller and the monitoring center, and facilitates integral debugging and acceptance of the distribution automation device.
