“…Magdun et al . [76] approximate the explicit representation of conductor locations in a slot using a continuum representation known as the foil approach [77] to determine resistances and inductances in 2D FEA while considering the skin and proximity effect. Resistance and inductance variation with frequency is modelled in the equivalent RLC distributed network by replacing the per‐turn resistance and inductance with a higher‐order RL ladder circuit.…”

Electric drive systems with long feeder cables connecting inverter and machine are used for oil exploration, mining, remote operated vehicles, industrial, and aerospace applications. Though this topology has the advantage of providing a better operating environment and easier serviceability for the inverter if the machine is located in an inhospitable and inaccessible environment, it does come with its own drawbacks. Steep-fronted switched voltages and cable-machine surge impedance mismatch can lead to high-amplitude, high-frequency (HF) voltage oscillations along the feeder cable, at the machine terminals, and throughout the machine's stator windings. These effects can cause high-electromagnetic interference, corona discharge, insulation failure in the feeder cable and machine's stator windings, common-mode, differential-mode, and bearing currents. This study discusses the HF issues relating to electric drive systems with long cable feeders. HF models for feeder cable and machine to analyse these phenomena are presented. The effects on long feeder cable loading on inverter switching characteristics are discussed. Methods to mitigate high-amplitude and HF oscillations in such systems are shown.

“…Furthermore, enormous efforts [7][8][9][10][11][12][13][14][15][16][17][18] have reported that the PWM voltage with a high slew rate leads to uneven distribution of voltage within the winding. These efforts have employed a HF model of the stator winding to understand the voltage distribution.…”

“…Many papers in literature [7][8][9][10][11][12][13][14][15][16][17][18] have availed the multiconductor transmission line (MCTL) model to predict the voltage distribution, however, they represented the HF behavior of the winding partially. Adjaey et.al.…”

“…However, at HF, when the skin depth is less than the laminate thickness, the flux produced by the winding penetrates partially within the iron core and induces eddy current. Therefore, the eddy current loss is incorporated and modelled as a resistance across a Г-cell in [14]. However, the mutual magnetic coupling between the turns is neglected.…”

The modelling and analysis of high‐frequency bearing voltage are of great significance to the assessment and mitigation of the electrical erosion risk in wind power systems. However, the dual‐winding permanent magnet synchronous generator (DW‐PMSG), as one of the mainstream models in wind power industry, has not been specifically analysed for its bearing voltage modelling method in the existing research. The high frequency common mode equivalent circuit model of DW‐PMSG is established, and the effect of parasitic parameters between two sets of winding on bearing voltage is analysed. A model parameters extraction method based on differential evolution algorithm is proposed, and the range of parameters is estimated by finite element simulation and test results, which improves the search efficiency and solution accuracy. The accuracy of the proposed model is verified by the comparison of simulation and experimental results. On this basis, it is possible to conduct more in‐depth research on the bearing voltage and bearing currents of DW‐PMSG, and provide theoretical basis and simulation means for the design of suppression schemes.
