Job Summary
In this project we will develop a physics inspired minimal stochastic model for partial discharges from first principles. We will begin by modeling PD activity originating from a single void with a fixed geometry. The initial goal is to generate partial discharge distributions that correspond to the measured data. A challenge is that the distributions are not stationary in time.
The final model should reproduce key statistical features of measured PD data and provide a physical interpretation of observed variations over time
Potential extensions of the project if time permits:
Thermal effects: temperature affects the material properties of the insulation material including the inception threshold for partial discharges and reaction rates creating feedback loops.
Void creation: voids are created in insulation material due to several mechanism such as mechanical stress and waxing. This formation in itself can also be modeled as a stochastic process.
Identify partial discharge events in raw partial discharge waveform measurement data.
Objectives
Perform a scan of the scientific literature on this topic
Build a minimal model that generates partial discharge distributions from a given geometrical void in a cable insulation.
Perform simulations using for example Monte Carlo techniques to generate partial discharge distributions and compare against measurement results.
