Control and Simulation Research on Interactive Oscillation of Operating Power of Diesel Generator Sets in Parallel

摘要

For some old diesel generator sets, interactive power oscillation often occurs in the parallel operation, owing to interference of oil supply. Through the analysis on the generator rotor equation, the paper first determines the cause of power change, and then uses control methods to eliminate the power interact oscillations based on actual conditions, and finally uses Matlab simulation to verify effectiveness of control methods.
