The present invention relates to an interval merging unit power factor angle consistency on-site test system and method, and relates to the field of verification of the intelligent transformer device. The test system comprises a 0.02 grade band origin merging unit tester and a 0.05 grade standard FT3 generation device. The test method comprises: the standard FT3 generation device simulates the real condition of the cascade interval merging unit of the transformer station on-site bus merging unit, the band origin merging unit tester can test the sampling synchronization precision, and the power factor angle error and the stable state error conditions of the cascade interval merging unit through receiving the digit output of the interval merging unit. The problem is solved that the test is difficult because the transformer station on-site bus merging unit cascade interval merging unit is too far, and therefore the verification work wiring is greatly simplified, and the debugging time is shortened. 本发明涉及种间隔合并单元功
