I am doing the initial design of a 300-megawatt solar project, and I am sharing its PVsyst simulation file for those who are interested.

In one of the projects that I had in one of the European Union member countries, CYM Software solved the following problem and modified the design of its plant system.
The values of step and touch voltages of the plant and the substation voltage were not suitable. Based on this, the amount of touch voltage in the marginal parts of the substation, including the fence area, which is particularly important because non-responsible people can touch it, is more than the permissible tolerance of the human body. be The first step in the design of the ground network is to correct the values obtained from the measurement of soil resistance. According to IEEE 81 standard, soil resistance should have a specific pattern. For this reason, the numbers obtained from soil testing should be verified against these patterns.
There are both manual and software methods for this. Its manual method is stated in the IEEE 81 standard, CYMGrd software can perform this analysis. This software calculates the pattern related to the soil test results, obtains a new number by interpolation for each of the numbers, and at the end also gives the error value of each number. The second step was to obtain the actual value of the Split Factor.
. According to the IEEE 80 standard, the strictest mode for GPR is that Remote Contribution is assumed to be 100%. According to what was said above, it is obvious that information such as the impedance of the transmission lines and distribution lines of the plant, the value of the local impedance of the transmission and distribution towers of the plant, etc. is needed to calculate the exact value of the Split Factor. To simulate the effect of bentonite, it was assumed that the resistance of the soil is reduced to 2.5 ohm meters by these items, which is an acceptable number. It was also assumed that 50cm of bentonite should be poured around each rod, which is a common number based on the details of common installations.
Vertical rods were added only in the fence area where touch and step voltage values were in the dangerous range. Also, due to the importance of these new rods, to increase the reliability of the design and also to further reduce the amount of resistance, these rods were connected by string wires.
With the measures described above, the values of touch and step voltages in the fence area were within the allowed range.

In the off-grid solar system design project referred to me to design and supply electricity for a 3D printer, the following file was provided to the German client for calculations and simulations
