The current electrified railway is forward developed in the direction of high speed and heavy load, and an electrified traction power supply system serving as a core technology of the current electrified railway becomes an important factor for influencing the future development of the electrified railway. The existing traction power supply system is out-of-phase power supply, such as direct supply, direct supply +reflux, AT and the like, and the problem that a power system is asymmetric to generate negative sequence current is solved, and the negative sequence current has great harm to the power system. Thus, in response to the above-described problems, in-phase power supply systems have been proposed and applied to electric railway systems. The in-phase power supply system can better solve the problems of asymmetry of the power system, low capacity utilization rate of the transformer, higher voltage and power loss of the traction power grid and the like.
In the construction process of the in-phase traction substation, as the main power supply loop is single-phase power supply, the loop current is large, and power transmission is completed by adopting a plurality of cables or wires, the electromagnetic field intensity is easy to generate around a loop path, the problem of overhigh temperature is caused by eddy current loss in a cable bracket, and the problem of exceeding magnetic field standard is easy to cause because the loop contains a reactor. Because a plurality of cable loops are adopted for supplying power, the laying mode of the cables with the same phase power supply is not a simple mode such as a straight line type mode, a delta type mode and the like. The occurrence of new problems requires specific analysis of specific problems at construction time. However, when the test is performed on the construction site, a large amount of manpower and material resources are consumed, and the reliability of the test result is not ensured, so that the construction efficiency is extremely low.

Outputting a final construction guidance scheme according to a result generated by the real simulation, including:
according to the determined preset parameters, carrying out real simulation on the actual construction scheme based on the simulation model;
and outputting a final construction guiding scheme according to the result of the real simulation.
In the invention, the actual construction scheme is that 76 in-phase cables are placed on a ZJ10 bracket. A schematic view of the cable holder and cable position is shown in fig. 9.
For this practical problem, consider 5 different cable arrangements, which are now numbered as follows for ease of description:
arrangement 1: the AAAAXXXX in the layers is arranged, and the currents in the layers are the same;
2, arrangement: intra-layer AXAXAXAX arrangement, inter-layer currents are staggered from each other;
3, arrangement: the AXAXAXAX arrays in the layers have the same interlayer current;
4, arrangement: the AAAAXXXX in the layers is arranged, and the interlayer currents are staggered;
5, arrangement: intra-layer AXXAAXXA is arranged, and inter-layer currents are the same;
for convenience of understanding, schematic diagrams of the current directions of the partial cables of the arrangement 2 and the arrangement 5 are shown in fig. 10 and 11, respectively, in fig. 10 and 11, a is the current inflow direction, and X is the current outflow direction.
And simulating the five different arrangement modes, and determining the temperature of the bracket under each arrangement mode according to simulation results. Through practical tests, according to the mode of arrangement 1, the temperature of the bracket is about 55.3 ℃; according to the arrangement mode of 2, the temperature of the bracket is about 23 ℃; according to the mode of arrangement 3, the temperature of the bracket is about 22 ℃; according to the arrangement mode 4, the temperature of the bracket is about 50.4 ℃; according to the arrangement 5, the temperature of the bracket is about 21.6 ℃. According to the simulation result, the intra-layer AXXAAXXA arrangement mode can be determined, and the bracket temperature can be minimized.
By arranging the cables in the layer in a staggered manner in the manner of 5, the heating problem of the cable support is greatly solved, because the heat generated by the cable support is from the eddy current loss in the cable support. According to ampere loop law, the cables are staggered in layers, so that opposite cable currents can be offset in a smaller loop range, the total current is zero, and the cable currents generate smaller magnetic fields for an external cable support, so that the generated eddy current is smaller, and the heat is less.
In the subsequent construction process, according to the arrangement 5 mode that the bracket temperature obtained by the simulation result is the lowest, the layers are arranged according to AXXAAXXA, and the optimal construction effect is achieved.
