Problems solved by technology

If the sub-gap layout of the spacer is unreasonable, the long-term and large-scale sub-gap oscillation will easily cause fatigue damage to the conductors and fittings, and even accidents such as wire whipping, which seriously threaten the safe operation of the transmission line.

Embodiment Construction

[0056] The present invention will be described in further detail below.

[0057] The present invention provides a method for optimally arranging the sub-gap of spacer rods, the method comprising the following steps:

[0058] Step 1: Calculate the maximum sub-gap under the condition of sub-conductor amplitude limitation;

[0059] The calculation of the maximum sub-gap is mainly based on the limitation of the sub-conductor amplitude, and the requirements of anti-adsorption conditions and torsional recovery characteristics are comprehensively considered; Avoid collisions when sub-conductors oscillate. The maximum sub-gap under the condition of sub-conductor amplitude limitation is represented by l, which is:

[0060] 2 X 0 = 0.0248 lV a / D T [ ...

Abstract

The invention provides a spacer subspan setting optimizing method. The spacer subspan setting optimizing method includes steps of calculating the maximum subspan under the condition of amplitude limit of sub-conductors; determining average subspan and subspan limits; setting up a penalty function to determine intermediate subspan. The spacer subspan setting optimizing method realizes optimized calculation and reasonable setting of spacer subspan by setting up the penalty function, so that subspan amplitude of divided conductors is effectively suppressed, and safety of circuit operation is improved.

Description

technical field [0001] The invention relates to an arrangement method, in particular to an optimal arrangement method for the sub-gap of spacer rods. Background technique [0002] Since the reform and opening up, my country's electric power industry has developed rapidly. Especially in recent years, with the continuous high-speed growth of electricity demand, the speed of electric power development has been further accelerated. The electric power industry is a basic industry related to the national economy and people's livelihood. Optimizing the allocation of energy resources, ensuring national energy security, and providing high-quality and reliable power supply for national economic and social development are important missions of the power industry in serving the construction of a socialist harmonious society. [0003] The split conductors of overhead transmission lines are prone to induce various forms of vibration under the action of natural wind, among which sub-gap ...
