Because the trend in small hydro-power micro grid flows bi-directionally, the traditional strategy which based on phase voltage change and load shedding has become increasingly unreliability. In order to adapt to the new application environment of small hydro-power micro grid, and to improve the protection installations, reliability and accuracy, longitudinal differential protection is used in power feeder with small hydro-power, so as to avoid the disadvantages of the traditional strategy. Constructing a micro grid with hydro-power stations working in isolated power grid by PSCAD/EMTDC software is used to prove that the strategy is effective and practicable .
