Assignment: Identification of illegally connected network segments and places with illegal power consumption.
Input data
30 transformer stations
(1200 consumption points)
- Hourly consumption profiles
- Instant voltage values
- PLC statistics and characteristics
Our solution
Determining suspicious network segments
- Creation of a topological model
- Estimation of missing voltage data
- Determination of the legal power flow
- Estimation of the actual power flow and calculation of the suspiciousness rating for each network segment
The result
With our method we have achieved 150% accuracy increase in determining the illegal connections, proven by physical inspections of the network (compared to the previously used method).
