Simulation Analysis of Dynamic Performance for Hydro-Generator Under Loss of Excitation Condition

Abstract

In order to analyze the dynamic performance for hydro-generator under loss of excitation (LOE) condition more effectively, based on MATALB, a mathematical model of hydro-generator under LOE condition is constructed in this paper. The model includes synchronous generator model, speed governor model, hydraulic turbine model, excitation regulation model and transmission line model. Several types of LOE faults are simulated by the model, and the simulation waveforms of related electrical quantities are compared with theoretical analysis result, thereby the feasibility of simulation model is proved
