Hello My name is Prayag Parikh. I am a Master’s student at University of North Carolina at charlotte. Topic of my today’s presentation is diagnostics and prognostics for multiple induction machines using a single set of current transducers. It is a part of my thesis. During this project I was helped by Rebecca, Arun and Jason. My work in this project was guided by my adviser Dr. Robert Cox.
Induction machines are the work horses of modern commercial and industrial applications. Induction machines are everywhere, in commercial-industrial buildings, power plants ,shipboards and air-plane. Failure of critical induction machine can cost millions of dollars in terms of cost of maintenance and lost of revenue. In some cases failure of induction machine can also jeopardize the safety of personals working on the floor.

Figure shows the block diagram of standard NILM. Typical installation location includes switchboards and motor control centers. From the block diagram it can be seen that NILM measures line voltages and aggregate current going to a bank of loads. Here data acquisition module converts analog data in to digital form with the help of 12bit A-to-D converter. Preprocessor uses these raw current and voltage data to get the active and reactive component of current. Event classifier uses preprocessed data to disaggregate individual load from the aggregate current data. Diagnostic and systems manangement module produces useful statistics for the operator, which can be used to analyze the health of different loads. Further slides will describe each block of NILM in detail.
Currently NILM is monitoring aggregate power flowing to loads of US Navy’s DDG-51 Land based engineering site. This site is a mock-up of no. 2 main engine room aboard a DDG-51 class destroyer. This site includes Low pressure air compressors for pneumatic valve actuation and tool operations. Figure shows the power drawn at one of the switchboards serving the DDG-51 Land based Engineering site. The beginning of each LPAC load interval has been shown with a circle. In this system compressor is running continuously, whenever receiver tank needs to be pressurized compressor is loaded and it consumes more power. Once the tank is properly pressurized compressor is unloaded and it consumes less power. Currently NILM logging load and unload intervals.
