Time-Series Data: How to Store SCADA Data with a Timescale/TSDB Approach (Partitioning, Retention, Query Performance) As real-time monitoring expands in energy facilities, the question “Are we collecting the data?” quickly turns into “How do we store this data for years and still query it fast?”. On the SCADA side, second-level (or higher-frequency) telemetry continuously streams [...] Read More
Real-Time Monitoring: How to Design Alarm Generation in SCADA (Threshold, Trend and Anomaly Approaches) When real-time monitoring in energy facilities (especially hydropower plants) is mentioned, many teams first ask, “Is data flowing on the screen?”. Yet operational value does not come from the flow of data; it comes from the operator seeing the right thing [...] Read More
OPC UA and Field Connectivity: How to Build a Secure “Field-to-Cloud” Data Flow for Hydropower Plants TL;DR OPC UA provides a security model that covers authentication, authorization, confidentiality, integrity, and auditability. [1][2] The safest pattern is controlled egress via an edge gateway and an industrial DMZ rather than exposing OT assets to the Internet. [3][4] [...] Read More
What Is SCADA? Which Data Are Critical in Hydropower Plants (HPPs)? TL;DR SCADA is a supervisory layer that collects field data and provides centralized monitoring/control through operator interfaces. [1][2] In HPPs, critical data include not only electrical measurements (MW, V, A, Hz) but also process and asset-health signals (flow, head, gate/guide vane position, vibration, bearing [...] Read More
