Abstract:
Double-circuit transmission lines parameters symmetry would affect the normal operation of the transmission lines and relay protection actions directly. This paper analyzes the impacts of three different phase sequence arrangements on parameters symmetry of conventional un-transposed double-circuit lines, and requirements can be met by the parameters symmetry for double-circuit transmission lines with different types and different length. Took practical engineering requirements into consideration, a simple and admissible suggestion on phase sequence arrangements and the transposition modes is

Abstract:
The verification of the limits of the population’s exposure to the magnetic field generated by double-circuit power lines from field measurements carried out on site is not trivial. It requires knowledge of the power line current instant values during the measurement period, the determination of the relationship between current and field at the measurement points (made more complex by the double-circuit overhead line configuration) and the use of that relationship to extrapolate the field values. Nevertheless, the verification of exposure limits for double-circuit power lines from on-site meas

Abstract:
With the continuous development of EHV (UHV) transmission lines,new lines often need to drill through the built lines,so it is urgent to study the type of diving towers. Based on typical weather conditions and commonly used ground wire models, the basic type and tower type selection of 110kV single and double circuit overpass towers in high altitude areas are studied, and two single and double circuit overpass tower schemes are planned and arranged. And according to the pole tower structure design and optimization theory, the 110kV single-circuit diving tower and the 110kV dual-circuit diving

Abstract:
In modern power transmission systems, the double-circuit line structure is increasingly adopted. However, due to the mutual coupling between the parallel lines it is quite challenging to design accurate fault location algorithms. Moreover, the widely used series compensator and its protective device introduce harmonics and non-linearities to the transmission lines, which make fault location more difficult. To tackle these problems, this dissertation is committed to developing advanced fault location methods for double-circuit and series-compensated transmission lines. Algorithms utilizing spar

This paper deals with the performance evaluation of cross-differential protection applied to double-circuit transmission lines which share the same tower, considering the occurrence of inter-circuit faults.
