SCADA and power systems knowledge built from real plant work — for engineers who commission, operate, and troubleshoot utility-scale PV.
A practical breakdown of reactive power behavior in inverter-based resources — dq-axis control concepts, IEEE 1547 ride-through requirements, and real commissioning failure modes from a 10 MW AC plant at 38.4 kV POI with an SEL-RTAC.
The practical difference between SCADA systems and HMIs — architecture, data flow, protocol roles, and how each fits on a solar plant.
How Q injection shifts apparent impedance on the R-X plane. Zone reach calculations with plant P-Q operating range.
Category A vs B reactive capability, voltage and frequency ride-through curves, and real field impact on DER performance.
Event class config, deadbands, binary input groups, and an interactive point list builder for your interconnect submittal.
Targeted technical content for every part of the engineering workflow.
