“…However, this method requires frequent friction or special magnetic field conditions, which may limit the applicability of this method in the application field. In [6], directional elements suitable for line connection and combined with time domain distance protection are put forward based on the R-L differential formula algorithm to improve the misoperation effect of transmission line distance protection. By deducing the analytical expression of fault current in the dq synchronous coordinate system, the fault current characteristics of IIRES and traditional AC power grid are summarized.…”

The working environment of the power system is complex and changeable, and transmission lines under different working conditions will face different conditions and requirements. However, previous studies often only consider the optimization of hardware under specific working conditions, ignoring the influence of other working conditions. To reduce the eddy current power consumption of hardware and improve the smoothness of optimization control, the optimization control method for the extremely low power consumption state of transmission lines is studied. We establish an optimization control model for the extremely low power consumption state of the transmission line hardware and use the wolf pack algorithm to solve the optimization control model and obtain the minimum eddy current power consumption value of the hardware. The experiment proves that it can effectively optimize and control the extremely low power consumption state of the hardware, with small absolute error integrals, and can effectively improve the energy-saving efficiency and power consumption reduction ratio of the hardware.
