Fingrid Oyj optimizes its power grid management with AVEVA PI System
Fingrid Oyj, Finland's largest electricity transmission system operator, needed a faster, smarter way to analyze and visualize its data to better support the national power system. The challenge was to develop analytical algorithms capable of making effective use of measurement data and strengthening operational decision-making. Deploying AVEVA PI System, complemented by AVEVA PI Vision, significantly reduced manual analysis, increased the effective use of data and enabled automatic fault processing as well as live modeling. Fingrid Oyj has already detected anomalies and performance errors that would probably have escaped any other approach, and that could have led to major disruptions of the power system. The solution opens up new ways to analyze and plan the grid, and has helped avoid numerous potential faults on three 400-megavolt-ampere transformers.
FAQ
How does AVEVA PI System help analyze data from a national power grid?
AVEVA PI System collects, contextualizes and historizes high-resolution measurement data from Fingrid Oyj's transmission grid. It automates analyses that were previously manual and tedious, and enables live fault modeling as well as automatic anomaly handling. For a transmission system operator, it is an essential foundation for real-time data management: it turns a massive volume of signals into actionable information that supports fast decision-making for power system stability.
What role does AVEVA PI Vision play in visualizing grid data?
AVEVA PI Vision provides Fingrid Oyj engineers with interactive dashboards built on data collected by PI System. Contextualized visualization replaces manual spreadsheet analysis and speeds up the detection of deviations. Combined with automatic fault processing, it has already helped identify anomalies on three 400 MVA transformers that could have caused major disruptions. It is an essential industrial monitoring lever for a transmission system operator.
Why automate fault detection in a power transmission grid?
With AVEVA PI System, Fingrid Oyj moved from time-consuming manual analysis to automatic fault processing. Automation detects weak signatures invisible to the human eye and alerts teams before a drift becomes an incident. For a national grid, this foresight is critical: it protects system stability, reduces repair costs and improves service quality. It is an emblematic use case of digital transformation in the energy sector.
What concrete results has Fingrid Oyj achieved with AVEVA PI System?
Fingrid Oyj drastically reduced the time spent on manual analysis, increased the effective use of data and enabled automatic fault processing. The solution made it possible to identify performance anomalies that would have escaped any other approach, notably preventing numerous potential faults on three 400 MVA transformers. Beyond grid security, AVEVA PI System opens up new ways of analyzing and planning the Finnish power system.
Why should a grid operator invest in a data platform like AVEVA PI System?
A transmission system operator handles millions of real-time measurements from high-voltage substations, lines and transformers. Without a dedicated platform, data remains scattered and underused. AVEVA PI System provides a layer of historization, contextualization and industrial analytics that turns these signals into operational value. It is a strategic investment to support the energy transition, the growing integration of renewables and the reliability of the national electricity service.
