Abstract
In industrial complexes and power stations a main source of power is connected to a motor bus to which motors and other loads are connected. In such systems an auxiliary source of power is provided to alternatively provide electric energy to the motor bus should the main source of power be interrupted. In the prior art digital system, samples are taken of the motor bus and auxiliary system voltage waveform with a fixed time window to predict the proper time for closing the breaker. The present invention improves on the prior art by applying the concept of an adaptive time window wherein the number of samples taken during each cycle to obtain the operating parameters is increased as the frequency decreases. This provides more accurate parameters for calculating the point for closing.
