Features
- Hardware architecture design is critical for the stability and availability of the entire system; the choice ensures that any single-point failure shall not affect the whole system.
- SmartAFL™ utilizes SEL-411L with capability for TW and DFR data collection in order to calculate distance-to-fault using both TW and Impedance method.
- SEL-3355 will be installed at the middle substation to collect, store and calculate fault location at the Centre. This industrial computer with no element rotation is designed specifically for use in environments that require high reliability
Functions
- SmartAFL™ software is developed by ATS with standard-based features, making it a hardware-vendor independent software that can protect utility investment and lower total cost of project ownership throughout its lifecycle.
- TW and Disturbance Impedance data is sent from Data Acquisition Units (DAU) to Data Acquisition Server via private WAN. Based on Travelling Wave and Impedance records of both ends and line parameters stored in system database appropriate distance-to-fault locating algorithms are executed with Automatic Fault Locating calculation engine. Operators are able to set up fault locating calculation in automatic or manual mode.
