AFAS Key Features

AFAS optimizes operational efficiency by offering:

Automated COMTRADE File Analysis
- Effortlessly groups related events using precise time alignment. AFAS automatically archives incidents as it receives COMTRADE files, ensuring efficient incident management.
Advanced Fault Detection & Analysis
- Identifies fault types, location, and severities with multiple single and double-end algorithms. AFAS offers insights into fault magnitudes, impedances, and sequence of operations.
Integrated Fault Analysis and Restoration
- Operates in conjunction with the ETAP FLISR module to provide simultaneous fault detection, analysis, and restoration strategies for systems with both transmission and distribution components.
Waveform Viewer with High-End Graphics
- Visualizes system data through an intuitive interface, supporting simultaneous COMTRADE file analysis. Users can explore phasors, RMS, and harmonic values, along with custom signal definitions.
Customizable Configuration
- Provides users with flexible analysis settings tailored to their unique operational needs to customize state and disturbance classifications, including Load Flow, Fault, Hot, Voltage Dip, Reacceleration, and more.
Model Verification and Signal Injection
- Utilizes line impedance estimation and signal injection (playback data) to verify model accuracy, ensuring protection schemes operate as intended.
eWeb Application for Result Visualization
- AFAS results are accessed through the eWeb interface, a secure and user-friendly platform for incident analysis and visualization. The eWeb is accessible via intranet or secure networks, offering flexibility and enhanced data protection.

How to Maximize Efficiency in Industrial Operations with ETAP AFAS

In Industrial applications, time is money. Quickly identifying faults and restoring assets is crucial to minimize downtime and costs. The ETAP AFAS (Advanced Fault Analysis Software) leverages disturbance records and telemetry data to locate faults and provide steps to restore assets while the fault is being addressed, increasing the chances of a quick resolution. Furthermore, ETAP AFAS seamlessly integrates several other ETAP software applications such as with the centralized relay management software (eProtect), eSCADA, and Intelligent Load Shedding (iLS) to provide a fully integrated solution for managing your industrial system. With this complete solution, engineers and operators can manage faults efficiently, minimize downtime, and maximize operational efficiency.

Learn about ETAP Automated Fault Analysis Software

ETAP Automated Fault Analysis System (AFAS) solution provides Real-Time and advanced analytics of electrical faults for your complex networks. Using the ETAP digital twin combined with disturbance records, engineers and operators have a clear forensic picture of any electrical fault in the network. Using proven ETAP analysis solvers, AFAS identifies faults, including fault type, start time, protection trip time, fault magnitudes, and fault distance/impedances. A novel signal injection features allow users to playback recorded data into the protection model to compare "as designed" vs. "as found" relay response. This comparison using ETAP electrical digital twin is used to validate system response per the configured protection scheme, and the sequence of operation was followed within expected time durations.

Demystifying IBR Fault Response with Parametric Modeling & Analysis

The fault response characteristics of synchronous generators are inherently governed by their physical attributes and construction. In contrast, the fault response traits of Inverter-Based Resources (IBRs) are intricately tied to manufacturer-specific control schemes and settings. This intricacy adds complexity to accurately representing IBR behavior during fault conditions, particularly given the rapid advancements in inverter technology and the diverse control strategies employed by manufacturers.
