基于时间序列电流偏差因子的电源-电弧系统稳定性研究
Study on WPASS Based on DTFCD
摘要
Abstract
Based on differential theory and considering the full load conditions from the external circuit on the course of dynamic welding,the research object was regarded as WPASS. Some models about the WPASS were found, they can obtain the analytic expression of system stability coefficient, and a qualitative analysis of WPASS' conditions,including its basic and optimal conditions. On the ba- sis of these, by the method of relative conversion of current deviation,a DTFCD was obtained by ana- lytical equation. Then, it was used to quantify stability of the system by the way of decaying time of deviation. Testing results based on experimental analysis of voltage and current waveforms, are the same to quantify WPASS based on DTFCD.关键词
