Detecting oscillations in an ABB variable frequency drive system (VFD) of large industrial blowers

Industrial blowers supply a huge flow of gas or air which are integral for functioning and operations of various process in the industries. Such examples are combustion, drying, aeration, cooling, air-cleaning, transport and many more. Oscillations are one of the parameters that could indicate potential issues with the machinery. A high speed data acquisition system is a reliable and sophisticated system that are ideal for this monitoring application. An example of such measurement applications is illustrated in the article below through oscillation measurement on the variable frequency drive system on a blast furnace blowers in the steel industry.
