Abstract
In the paper operating mode simulation of a hydro-generator with armature winding taps, running under standalone load with thyristor auto ballast stabilization system of magnitude and frequency of the output voltage of a hydraulic unit has been conducted. The created model enabled to investigate steady-state operation of the plant when connecting ballast load to various winding taps of the hydraulic generator subject to power change of the plant workload. Stabilization of the magnitude and phase of hydro-generator equivalent load as well as the distortion degree of output voltage for each stage of ballast have been evaluated. Ballast stage control algorithm and control laws of gate switching angles of ballast regulator have been proposed. Studies were undertaken within the scope of the RFBR grant entitled “Research and development of micro hydro power plant control systems for the power supply of standalone consumers”.
