摘要：
To accurately and efficiently realize the simulation of complicated DC distribution systems, the essential ingredients of dynamic phasor-electromagnetic transient hybrid simulation applied to the DC distribution system are analyzed, which includes subsystem modeling, interface mechanism, and data interaction sequence. Starting from the error generation principle of hybrid simulation, the electromagnetic transient subsystem is taken as the main focus, of which the error transfer process is analyzed in two cases of simple resistive-inductive branch and complex system, as well as the necessary conditions of numerical stability. Then, the serial sequence is employed for designing the main algorithm of dynamic phasor-electromagnetic transient hybrid simulation, and the corresponding accuracy improvement methods are also proposed, including the correction for extracting dynamic phasor, and the addition of DC-side characteristic ripple. Finally, the isomorphism hybrid simulation platform based on MATLAB/Simulink is implemented. Through the comparison with the full electromagnetic transient simulation, the efficiency of the hybrid simulation, as well as the validity of the improvement methods, can be demonstrated,.. ©2023 Chin.Soc.for Elec.Eng.
