Mathematical Function of a Signal Generator for Voltage Dips Analysis

This paper presents a mathematical model for a complex voltage dip signal generator, that can be used to generate waveforms similar to those recorded. The voltage dip signal generator is designed to shape the voltage waveform for normal operating conditions, during the voltage dip stage and the transition between these two situations. The advantage of using a generator instead of real data measurements, is that the dip parameters are known, and un this way, it can be detected if the specific algorithms used for voltage dips analysis give the same results. The mathematical model can be implemented in different software used for voltage dip analysis. To demonstrate the complexity of the voltage dip generator, the corresponding mathematical model was implemented in MAPLE and use to generate some voltage dips with particular characteristics.
