Abstract

As a research method a mathematical simulation on computers may be carried out by the numerical solution of a number of non-linear differential equations describing dynamic processes in micro hydroelectric plants during the starting-up of induction motors (IM). It is suitable to present equations for IM as a coordinate system rotating at the samerate with stator field. This permits to take into account the changing frequency of power voltage, becouse of different speeds of response current and frequency channels are functioning with shift in time. The studies show that in order to use to a full extent the good dynamic properties of a current channel it is necessary to distribute current balast power and frequency balast power as 4:1. With such power distributions of control channels the dynamic properties of a micro hydroelectric power plant are practically similar to these proputice of the plant with autobalast. Resetting time of turning frequency of the hydroplant is being reduced by 0.1-0.2 sec due to the frequency channel action.
