ABSTRACT:According to the productive characteristics of ac electric arc furnace (EAF), the mechanism of active power impact caused by EAF was explained. Estimating the magnitude of impact, distribution of the impact in the network (generating sets) was analyzed. The influence of the active power on generating sets were discussed. On the relative data of several large projects in China, the limits of active power impact for steam turbo-generator were summarized. Finally, the technical measures for decreasing active power impact of generating sets were outlined briefly.
