MiAFAS™ – MiPower® Automated Fault Analysis System


Ground breaking innovations in protection and communication technologies and intelligent protection systems are generating voluminous data. Following a disturbance, a protection engineer is entrusted with the responsibility of analysis of such unstructured data, to better understand the behaviour of protection system.

Timely analysis/assessment and taking corrective actions of such a data helps in great way in operating the power system in a reliable manner. Traditionally, this would take few days to few weeks for the utility personnel to derive insights and come up with remedial measures if any. MiAFAS™ completely automates this and provides concise information in minutes, enabling faster decision making and reduce operational cost.

Why MiAFAS™ ?

MiAFAS™ adds value to operations in multiple dimentions:
  • Reduces Analysis time
  • Performs in-depth analysis
  • Helps to comply with regulatory authorities
  • Enables data mining on fault data
How it works ? The disturbance data collected (in COMTRADE format) from protection equipments get transferred to central processing system. MiAFAS™ preprocessing engine checks for validity of the file(s) and passed through the analysis engine which analyzes the data using various intelligent algorithms pre-defined fault signature and generates a detailed report.
Major Types of Analysis
Current Deployments Currently MiAFAS™ is installed in one of the Indian state-owned electric utility company which transmits about 50% of the total power generated in India on its transmission network. More than 230 substations and 8000+ numerical relays across India are integrated with MiAFAS™. The voltage levels include 132kV to 765kV. The system is in operation since 2018. Apart from this, MiAFAS™ is being supplied to two more state transmission utilities in India. Refer to brochure and other materials for more information.
