Abstract

Operating a hybrid HVAC and HVDC power transmission line is an option for increasing the efficiency of power transmission and overcoming the difficulties in obtaining a new right-of-way. This paper proposes a new calculation method for the study of hybrid power line corona. The proposed method can be used to calculate DC corona losses and corona currents in DC or AC conductors for single phase AC and monopolar DC hybrid lines. Profiles of electric field strength and ion current density at ground level can be estimated. The effects of the presence of an energized AC conductor on DC conductor corona and DC voltage on AC conductor corona are included in the method. Full-scale and reduced-scale experiments were utilized to investigate the hybrid line corona effects. Verification of the proposed calculation method is given
