This paper systematically studies the effect on the high level of reactive voltage with small hydropower plants connect?ing to the distribution network. Besides, it establishes the simula?tion model of the small hydropower in the wet season, and proposes the methods of generators leading?phase operation and the distrib?uting shunt reactor. It focuses on comparing the effect of shunt re?actor located on high?level and low?level side of small hydropower transformer. The results show that the quality of reactive power and voltage has been significantly improved, when the shunt reactors in?stalling on the low voltage side of transformer and then achieve bet?ter economic and social benefits.
