Collaborative test system and method for primary frequency modulation master station and secondary station

The system comprises a primary frequency modulation test function module located on a scheduling side, a PMU data concentrator located on a power plant side, a test substation device located on the power plant side and a test substation background located on the power plant side. According to the invention, on one hand, when the scheduling side performs the primary frequency modulation performance test, the power plant side can perceive and perform the primary frequency modulation performance evaluation calculation at the same time, and on the other hand, on the condition that the power plant side obtains the authorization of the scheduling side, the power plant side can actively perform the primary frequency modulation performance test and timely find out the problem of insufficient performance of the own frequency modulation system; according to the invention, various unnecessary assessment fines are reduced while the due contribution to the power grid is exerted, the defect that the existing primary freque
