摘要：
As a renewable resource, small hydro is gaining more and more attention due to its variable advantages. The paper focuses on the operation of the micro-grid based on small-hydro. A simulation model of the micro-grid is established by Simulink, which takes the following two cases into account, the grid-connected operation and isolated operation. Under these two cases, the differences of the excitation voltage and rotator speed are analyzed respectively. Power quality of the voltage is also analyzed. Faults are pre-set in the grid and micro-grid. Then the operations of the micro-grid when faults happen are simulated. By comparison of the results, the effects of the fault-cutting-off time are discussed.
