Main initiated linkage test system and method

The invention discloses a main initiated linkage test system and method. The system is composed of an upper computer, a programmable controller, a contactor, an auxiliary power unit, a digital controller panel, a generator, a purely resistive adjustable load and a generation controller. The generator, the purely resistive adjustable load, and the contactor are connected in series successively to form an electrical loop. Main initiated starting signals on the digital controller panel are divided into two paths; at one path, the programmable controller controls the coil of the contactor to open or close so as to realize connection or disconnection of the electrical loop; and at the other path, a fuel adjusting value of the auxiliary power unit is connected to adjust the fuel amount. Besides, a main initiated starting key is arranged on the digital controller panel; and the programmable controller is used for processing a loading signal and a main initiated starting signal, so that the loading signal and the mai
