“…Vector fitting in [31,32] is used in [33,34] to fit a rational approximation transfer function in the frequency domain to measure short circuit and open circuit impedance data using poles and residues. It is a pole relocation technique where the poles are iteratively improved in the least squares manner until convergence is achieved.…”

“…Since the use of an RL-network only allows the use of real poles and residues in the fitting, the complex terms are discarded which in turn affects accuracy. The authors of [34,35] extend this RL model by using a resistor-inductor-capacitor (RLC) network to include complex poles and zeros in the fitting as seen in Fig. 11 using the expression as shown…”

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.

“…Regarding this issue, several contributions have been done in order to improve the damping characteristic of the traditional Pi model. In general terms, these contributions consist of including the inductive coupling between the cable layers (core and screen) [5] or by including equivalent networks that represent the variation in frequency of the cable parameters [4,6]. The model proposed in reference [4] eliminates the contribution of the cable screens by assuming them to be at ground potential (even though they might not be grounded at both ends).…”

“…The model proposed in reference [4] eliminates the contribution of the cable screens by assuming them to be at ground potential (even though they might not be grounded at both ends). On the contrary, references [6,7] represent a cable system with a Pi equivalent circuit including the frequency dependence of the cable longitudinal impedance in the modal domain. For this model approach, transformations between both domains, phase and modal, are required.…”

Frequency-Dependent Pi Model of a Three-Core Submarine Cable for Time and Frequency Domain Analysis

et al. 2018

In this paper, a Frequency-Dependent Pi Model (FDPi) of a three-core submarine cable is presented. The model is intended to be used for the representation of submarine cables in an Offshore Wind Power Plant (OWPP) scenario for both time and frequency domain analysis. The frequency-dependent variation of each conductive layer is modeled by a Foster equivalent network whose parameters are tuned by means of Vector Fitting (VF) algorithm. The complete formulation for the parameterization of the model is presented in detail, which allows an easy reproduction of the presented model. The validation of the model is performed via a comparison with a well-established reference model, the Universal Line Model (ULM) from PSCAD/EMTDC software. Two cable system case studies are presented. The first case study shows the response of the FDPi Model for a three-core submarine cable. On the other hand, the second case study depicts the response of three single-core underground cables laying in trefoil formation. This last case shows the applicability of the FDPi Model to other types of cable systems and indirectly validates the response of the aforementioned model with experimental results. Additionally, potential applications of the FDPi model are presented.
