Minimizing the three-phase unbalance in an electric arc furnace
IEEE Transactions on Magnetics, 1989A method is proposed to reduce impedance imbalance in the electrode arms of an arc furnace. Conducting plates or tubes are used to shield the magnetic fields around busbars in order to minimize the mutual inductance. The volume integral equation method is used to calculate bus impedances, current distribution, and eddy current losses.

This paper evaluates the influence of the unbalance factors in calculating total copper losses, efficiency, power factor, input power, output torque, peak currents, and derating factor of the motor operating under unbalanced voltage system. The complete definition for the voltage unbalance is using complex voltage-unbalance factor that consists of its ...

SUMMARYFrom the global environmental viewpoint, distributed power systems using renewable energy source, such as solar power, wind power, and water power, are attracting much attention. Photovoltaic (PV) systems using solar power have few resource constraints and can be installed easily on the roofs of houses.

Three-Phase Unbalance Compensator Using Neutral Point Clamped Multilevel Interleaved Inverter
2018 IEEE 4th Southern Power Electronics Conference (SPEC), 2018This paper proposes a three-phase unbalance compensation system using interleaved NPC inverter and a fast current regulation method. The proposed compensator can reduce in volume of passive filters and voltage and current stress on power devices by using NPC and interleaved circuit structure.

Optimal control of three-phase PV inverter under Grid voltage unbalance
2019 21st European Conference on Power Electronics and Applications (EPE '19 ECCE Europe), 2019Typical three-phase PV inverter is designed to operate under balanced grid voltage conditions. At low voltage distribution grid, beyond utility power meters, grid unbalance conditions can be often found. Under grid voltage unbalance, a typical three-phase PV inverter with conventional control exhibits poor performance resulting in potential loss of ...

The influence of grid-connected three-phase inverters on voltage unbalance
IEEE PES General Meeting, 2010The increasing presence of single-phase distributed generators and unbalanced loads in the electric power system may lead to unbalance of the three phase voltages, resulting in increased losses and heating. To decrease this voltage unbalance problem three-phase four-wire inverter-connected distributed generation units may be used.

Study of the apparent load loss unbalance in three-phase transformers
Canadian Conference on Electrical and Computer Engineering, 2005., 2006In a three-phase transformer, the load losses are generally similar between phases, with some small variations due to the proximity of the tank on lateral phases. However, when a three-phase test configuration is used, the measured active losses in each phase are significantly unbalanced and do not reflect the actual losses in each phase.
