Import load profiles
Polysun SPT requires a certain formatting of csv-files, so that they can be read in.
Please format your load profile as follows:
- column: Energy consumption (with . as decimal separator)
- column: Time interval in seconds (optional)
Example (represents a year with 365, resp. 366 days in 15-min resolution)
For a resolution of 15 minutes the result is 35040, resp. 35136 lines.
An example, how it must look in the csv:
| Column 1 | Column 2 |
|---|---|
| 0.4 | 0 |
| 0.3 | 900 |
| 0.5 | 1800 |
| … | … (top line + 900) |
| 0.4 | … |
| 0.2 | 31535100, resp. 31621500 |
Consequently, the second column of the last line contains the last second of the year (a year with 365 days contains 31536000 seconds and a year with 366 days contains 31622400 seconds). Since the first row contains the value 0, the last entry is smaller than the number of seconds per year. If you read in a file with only one column, based on the number of rows the time intervals are automatically filled in and displayed in the preview.
Alternatively, an hourly resolution with fewer entries would also be conceivable.
Example (represents a year with 365 days in hourly resolution)
A profile with hourly resolution and 8760 lines is mapped in Polysun SPT as follows:
| Column 1 | Column 2 |
|---|---|
| 0.4 | 0 |
| 0.3 | 3600 |
| 0.5 | 7200 |
| … | … (top line + 3600) |
| 0.4 | … |
| 0.2 | 31532400 |
