文摘
- •
In this work a state estimation approach is used to determine the fault distance.
- •
Measurement and digitization errors are being modeled in the estimation process.
- •
A region of probable fault occurrence is delimited with 95% of success probability.
- •
The methodology was tested successfully for simulated and real transmission lines.
