Gate-position and Turbine-generator Unit Speed Signal Approximation with Fuzzy Clustering for TS Fuzzy Model

Abstract

Takagi-Sugeno (TS) type of fuzzy models for data-driven set has attracted a great deal of attention of the fuzzy modeling community due to its satisfactory performance in various applications. In this paper, an application of TS model is described to obtain approximated input-output response of turbine-generator unit in a hydro power plant operating as an isolated system. The rule-base is generated independently each for input and output response using fuzzy c-mean (FCM) and Gustafson-Kessel (GK) algorithms with antecedents determined using product space. The model simulations are demonstrated for 50% decrease and 10% increase in load disturbance from rated conditions
