We've now introduced expanded options for customizing your substation and overhead line. We'll teach you the best practices for these features.
In this article, we will present the new features that were developed for overhead line design. This allows you to find a more flexible solution to meet with your requirement.
Customize your overhead line
Now you will be able to define your own overhead line (OHL). All you need to do is to set up the values and choose the preferred components used for your OHL.
There will be three values to define:
1. Capacity over estimation: So far, pvDesign estimates the capacity automatically based on the plant design. But you can increase this value to adapt to your needs, and the designing of the OHL will be based on this over-estimated capacity.
2. Number of circuits: You will be able to change the number of circuits to be used for your OHL, either 1 (Simplex) or 2 (Duplex).
3. Number of conductors per phase: You can decide how many conductors to include per phase, you can choose from 1 up to 4.
You will be able to selected your preferred phase conductors, earth wire, and tower shape.
- Phase conductor: You can choose either by using AAAC(Aluminum composed conductors) or ACSR(Aluminum and steel composition). We provide you with a range of conductors for each one which is used widely in the industry.
- Earth wire: pvDesign provides you with various fiber optics earth wires to choose from.
- Tower shape: You will have 6 options for your tower shapes depending on how many circuits you have.
In the case where you have a double-circuit transmission line, each circuit consists of three conductors corresponding to six phases, you will have three types of tower shapes for these phases.
If you have a single circuit, there will be three phases in total corresponding to three tower shapes.
The calculation and design will be based on the inputs you set, more information on the considerations of each input can be found in our updated methodology with the new features here.
