Frequency characteristic of generator park of the national interconnected system of Ecuador

Abstract:

This paper presents the frequency characteristic curve of a real hydrothermal system using speed droop each generator for determinate the speed droop equivalent. The elaboration of the frequency characteristic curve is based on the parameters of each unit. The determination the frequency characteristic curve is building for each individuality speed droop into limits of capacity. The frequency characteristic curve is no lineal due of characteristic technique of generators and variability of demand. Power electric system has different dispatch for hydrological cycle of hydroelectric power unit that determine of unit commitment of thermic generator, thought. Speed droop is different since it more dispatch unit. The proposed methodology is implemented in MATLAB® and EXCEL® and its performance is evaluated using the National Interconnected System of Ecuador to determine frequency characteristic curve the economic load dispatch of thermal units on weekdays of each period hydrological.
