Optimization of zero-sequence voltage compensation for zero-sequence directional elements

Electric Power Systems Research, 2021
Abstract 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.

Zero Sequence Voltage Control Enabling Transformerless Electric Vehicle Chargers

2021 IEEE Transportation Electrification Conference & Expo (ITEC), 2021
The transformer is one of the most bulky, expensive and lowest efficiency components in a typical electric vehicle charging system. Its removal is conducive to enabling greater proliferation of charging infrastructure and the adoption of electrified vehicles.

Flux-Weakening Control for Variable Flux Reluctance Machine Excited by Zero-Sequence Current Considering Zero-Sequence Resistive Voltage Drop

IEEE Transactions on Energy Conversion, 2021
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.

Signal processing of zero sequence voltage technique

2007 European Conference on Power Electronics and Applications, 2007
This 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

Managing zero sequence in voltage source converter

Conference Record of the 2002 IEEE Industry Applications Conference. 37th IAS Annual Meeting (Cat. No.02CH37344), 2003
The 3-phase bridge voltage-source converter (VSC) which has been and continues to be the work-horse of variable-speed AC-motor drives is making penetration into the electric utility environment. In the electric utility environment, there is a greater emphasis on: (i) grounding and (ii) the need of the VSC to survive all conceivable faults.
