The invention relates to AVC control, in particular to a small hydropower station AVC control system, and aims to overcome the defects that in the prior art, control interfaces and communication protocols are not unified, so that voltage and current data are difficult to collect, and long-distance data transmission is not reliable enough. The AVC control system for the small hydropower station comprises an AVC controller arranged in a remote control center, and voltage and current acquisition units arranged at a hydro-generator and a grid-connected point, the voltage and current acquisition unit comprises a plurality of collectors used for collecting current transformer signals and/or Rogowski coil signals and voltage transformer signals. The plurality of collectors are respectively arranged on a hydro-generator and a grid-connected point; the plurality of collectors and the concentrator board card module respectively form a bidirectional data transmission loop through two paths of optical fibers, and the con
