摘要
针对河北国华沧东发电有限责任公司3号机组励磁系统功率柜电流输出不均衡的问题,从可控硅脉冲触发回路、可控硅参数及特性、交直流回路等效阻抗差异等方面进行分析,认为电流输出不均衡的主要原因是各功率柜交流回路的等效阻抗存在差异,提出在交流进线处加装磁环的改造措施。
In view of unbalancing current of excitation system output in Hebei Guohua Cangdong Electric Power Co. Ltd. No. 3 unit,this paper analyzes from the aspects of SCR pulse trigger circuit, SCR parameters and characteristics, and ACDC loop resistance and inductance issues, and considers that the main reason is the differences of the equivalent circuit resistance,proposes the measures that installation of flux divert on AC input.
