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.
