تخمین پایداری ولتاژ سیستم قدرت با استفاده از شبکه های هوش مصنوعی

سال انتشار مقاله:2012   Abstract Voltage stability is concerned with the ability of a power system to maintain acceptable voltages at all buses in the system under normal conditions and after being subjected to a disturbance. This paper presents a new technique to determine the static voltage stability of load buses in a power system for a certain operating condition and hence identifies load buses which are close to voltage collapse. A voltage stability index with respect to a load bus is formulated from the voltage equation derived from a two bus network and it is computed using Thevenin equivalent circuit of the power system referred to a load bus. . Buses with values of voltage stability factors close to 1 .0 are identified as the critical buses. And after that, an Artificial Neural Network is developed for voltage stability monitoring. In ANN applications, selection of input variables is an important aspect چکیده: پایداری ولتاژ به توانمندی سیستم قدرت در حفظ ولتاژ قابل ...
