Automatic multi-vendor IED fault data collection and analysis solution

Abstract

Smart automation technologies aim to improve efficiency and productivity in several areas. Specifically for power system disturbances, automation can greatly reduce capital and labor costs by not only reducing travel time to substations to collect event data but streamline event response processes. A key concept in fully achieving this type of automation involves solutions that not only support automated fault data collection from IEDs, but automated fault data analysis as well. The fault data collection was a challenging feat for a utility from the Dominican Republic where their power system consisted of a breadth of multi-vendor devices such as SEL, GE, ABB, Siemens, ERLPhase, EMAX, APP, and Qualitrol. This presentation details the integration of three multi-vendor solutions that provided the utility with a complete vendor agnostic system to achieve the following benefits: • A centralized IED management solution that supports automatic multi-vendor event data retrieval • Email notification, version control and archival of ollected records • Secure authentication to a web-based interface to access and conduct in-depth post-event analysis • Automatic conversion of proprietary event record formats to open standards such as COMTRADE • Automatic event record analysis that summarizes disturbances and calculates Takagi, Modified Takagi, and Novosel fault location • Ability to integrate with other business intelligence systems such as Enterprise Resource Planning systems like SAP to historians from OSIsoft, Schneider Wonderware eDNA, and Automsoft that can be utilized for breaker analytics and trending.
