In the control of variable flux reluctance machine (VFRM) excited by zero-sequence current, neglecting the zero-sequence resistive voltage drop would cause a large calculation deviation of the stator voltage, which can saturate the inverter and influence the switching from constant torque region to flux-weakening region.

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021
This article introduces a capacitor-voltage-balancing method based on optimal zero-sequence voltage injection in a stacked multicell converter (SMC). The proposed method is implemented using hybrid carrier pulsewidth modulation and is capable of balancing and regulating the voltages of dc-link capacitors and floating capacitors in the topology.

On-Site Low Voltage Determination of Zero-Sequence Impedances for Power Transformers
IEEE Transactions on Power Delivery, 2020Accurate zero-sequence transformer data is important for correct fault analysis and protection settings. Utilities have been forced to approximate zero-sequence impedances for many three-legged core power transformers in service today that did not undergo testing for zero-sequence data at the factory before site installation. Where approximation of the

Optimization of zero-sequence voltage compensation for zero-sequence directional elements
Electric Power Systems Research, 2021Abstract Compensating zero-sequence voltage measured is an effective measure to improve the sensitivity of zero-sequence directional overcurrent protections. However, when applied to double circuit power supply system, it may lead to misjudgment of zero-sequence directional elements.

Signal processing of zero sequence voltage technique
2007 European Conference on Power Electronics and Applications, 2007This paper deals with the implementation of the zero sequence voltage (ZSV) technique [4,7], which was exploited to determine the rotor position of the surface permanent magnet synchronous motor (SMPMSM). The method is based on the zero sequence voltage measurement, performed between the neutral point of AC machines and the mid-point of the inverter DC
