Kampusareena Solar Power Plant Inverters (demo) [Draft]

Note: This is a demo version of the dataset.

Overview

This dataset contains electrical measurements from the four inverters of the Kampusareena building's solar power plant. The plant has a maximum power production capacity of 57 kW, with the power output directed to the top floor ventilation machine room.

Solar Power Plant Specifications

• Total Capacity: 57 kW
• Location: Kampusareena building, Tampere University

Inverter Configuration

The solar power plant consists of four inverters distributed across three walls:

1. West Wall:

2. 1x SMA STP8000TL (8 kW)

3. Southwest Wall:

4. 1x SMA STP15000TL (15 kW)

5. Southeast Wall:

6. 2x SMA STP17000TL (2 x 17 kW)

Measurements

The dataset includes various electrical parameters, such as:

• Frequency
• Current
• Voltage
• Power
• Energy

Data Collection Frequency

• Most data: 1-second interval
• Static inverter data: Once per day or upon collector restart (marked as "read once" in the available measurements list)

Important Notes

• Data Quality Issue: Data collected before 2018-08-08 may contain erroneous values (large negative numbers like -2147483648). This occurred when the collection system misinterpreted the "no data" signal from non-operating inverters, often during nighttime.
