A Modified Nonlinear Hydro Turbine Model

Abstract:

The power system simulation software usually use ideal hydraulic turbine model in transient stability simulation. Ideal model is the linearization of turbine steady state equation, it can hardly adapt to the various operation conditions in power system. In this paper, a modified nonlinear model of hydraulic turbine is proposed based on basic hydraulic turbine equations, the model can better reflect the dynamic behavior of the turbine since transient component are taken into account. Field test data verify the validity of the proposed model. The model can greatly improve the accuracy. Furthermore, the model is very simple so that it can be easily used in power simulation software
