Electrical measurement data from the four inverters of the solar power plant of the Kampusareena building. Rated total inverter power of the solar power plant is 57 kW. Maximum power of the solar panels is 82 kW. The solar panels are installed on three walls of the building that face different directions. The solar power plant feeds the top floor ventilation machine room, thus the ventilation system of the building. Collected measurement quantities include frequency, current, voltage, power and energy of each inverter.
The inverters are the following:
- SMA STP8000TL (8 kW)
- SMA STP15000TL (15 kW)
- SMA STP17000TL (2 x 17 kW)
Most of the data is collected with 1-second interval. However, there are some static data about the inverters that is fetched only once per day or whenever the data collector is restarted. These values are marked as read once in the available measurements list.
Notes:
- Data collected before 2018-08-08 may contain erroneus data in the form of large negative numbers like -2147483648. This is because the collection system misinterpreted the value signaling that there were no data since the inverter was not operating. This often occurred during night time.
See the ProCem project for general information about how the measurements are stored and how they can be used. See the Kampusareena group for general information about the building.
