摘要：
In order to smooth ADPSS electromagnetic transient simulation, three-phase load flow modeling and computation method based on electromagnetic transient model library are studied in this paper, and three-phase load flow program is implemented in ADPSS. The electromagnetic transient models areclassified first. Then influence of transformer connection on system phase angle is studied, anda new transformer modelcompatible with various transformer connections is built. Based on research conclusion of various three-phase power flow algorithms, Newton-Raphsonmethod isused on account of prospect and practicability, and three special nodetypes are set up to meet asymmetric computation requirements. Finally, correctness of the new program is validatedwith the first two examples, and theother examplesare given to demonstrate usability of the new power flow results to provide initial values for electromagnetic transient simulation. © 2018, Power System Technology Press.
