Low frequency oscillation is the potential threaten to the stability and security of the large AC/DC interconnected power system. Fast and effective modulation controller is one of the effective ways to solve the problem. Introduction about the realization of user defined modulation controller (UDMC) in small signal analysis package (SSAP) developed by Shanghai Jiaotong University, which has been applied in analysis of the large power system, is present in this paper. The modeling of UDMC is based on the component connection modeling idea, and UDMC accords with the universal component connection method in SSAP to participate in the formation of system state matrix. UDMC is the foundation for future research on modulation controller.Analysis of specific case validates the correctness of the UDMC function.
