Simplified Modeling of Hydraulic Governor-Turbine for Stable Operation under Operating Conditions

摘要

Power system performance is affected by dynamic characteristics of hydraulic governorturbines during and following any disturbance, such as occurrence of a fault, loss of a transmission line, a rapid change of load or hydraulic transients. Accurate modeling of hydraulic governor-turbines is essential to characterize and diagnose the system response during an emergency. In this paper, the identification, development and implementation of hydraulic systems in power plants has been done via literature survey and computer based simulations and analyzed by comparing different models through simulation in MATLAB/SIMULINK. The results obtained provide an insight into the interaction between electrical and hydraulic system of hydro power plant governed by different governor settings, so that the system may remain unaffected during any disturbance.
