摘要
针对某电厂励磁系统均流问题进行分析,通过理论论证了导致均流问题的2个主要原因:交流输入阻抗的差异、整流装置运行点与可控硅额定工作点的差异,并通过实际试验的方法进行了验证。
The current sharing problem of excitation system in one power plant is analyzed in the paper.The change of AC input impedance and the difference between operating point of rectifying device and rated operation point of SCR are proved to be the main reasons for the problem in theory,and actual test is in conformity with the theoretical analysis.
