Description
e-PCM monitors the condition of generators and their prime movers, effectively using the generator itself as a sophisticated transducer. It uses advanced NASA-developed technology to provide automated set-up and fault diagnosis with minimal user intervention. It is simpler to use and more cost-effective than conventional systems. e-PCM is applicable to a very wide range of equipment, including turbo-alternators, diesel generators, and wind turbines, and is particularly valuable for equipment in inaccessible or hazardous environments.
How it Works
e-PCM creates a digital twin of generators and their prime movers such as wind turbines. The digital twin is built up during self-learning phase of operation. During this phase the three voltages and three currents are continuously measured and processed using system identification algorithms which determine the model parameters under a full range of operating states.
When a fault starts to develop in either the generator or the prime mover, this has an effect on the current waveform, making the real system behave differently from the model system. This allows e-PCM to use the generator as a sensor that can detect faults in both the generator and the prime mover. e-PCM continuously compares model parameters with those held in the reference model.
