Abstract :
A 15~20Hz low-frequency oscillation (LFO) will badly harm the safety of 4-wire multi-phase generator-rectifier-load systems. This paper studies the LFO in a 4-wire 12-phase generator-rectifier-resistance load system by simulation and experiment. The simulation model of 12-phase generator is programmed in FORTRAN language by secondary development with PSCAD/EMTDC software, and validated by a hardware experiment. The effects on the LFO from various system parameters, such as capacitance of filter capacitor, load resistance, leakage inductances of armature windings and field winding, saturation, and resistances of damper windings, are studied with the simulation model and hardware system. The extracted rules in this paper provide a reference for correlative research and design.
