| description | This paper investigates the feasibility of magnetic fields reduction by optimization of phase relationships in a multi-circuit underground power cable system, carrying unbalanced loads. A novel algorithm was developed for fast calculation of the multi-circuit power cable system-generated magnetic field. The unbalanced load was modeled by random selection of phase current values. A computer code was written to calculate the statistical distribution of the magnetic field above the cables on the ground level. The program calculates the maximum magnetic field for different phase relationships and selects the optimum phase relationship. Several multi-circuit power cable systems used by electric utilities have been analyzed. The results show that the optimization of phase relationships effectively reduces the magnetic field for power cable systems with both single and multi-point grounded sheaths in spite of the load unbalance. |
