Learn how a STATCOM provides dynamic reactive power and voltage support, how it compares with SVCs and capacitors, and how engineers size it for weak grids.
Learn power system protection schemes from generator to load, including protection zones, relay coordination, device numbers, backup protection, and settings.
Understand PRC-029-1 compliance deadlines, IBR ride-through requirements, R1–R4, enforcement discretion, notification rules, and owner action steps.
Learn where zero-sequence current comes from in inverter-based plants and how transformer grounding affects ground faults, overvoltage, protection, and interconnection.
Learn how VFD cable length, voltage class, reflected wave and motor insulation determine when to use an output reactor, dV/dt filter or sine-wave filter.
Learn how available fault current, SCCR and interrupting ratings affect equipment safety, short-circuit studies, arc flash risk and electrical system design.
Explore the 3,800 MW data center load event, why a cleared 230 kV fault triggered load transfers, and what it means for ride-through and grid reliability.
Learn how CAISO BESS projects manage test energy before COD, including WECC modeling, EMT studies, telemetry, ride-through, registration and compliance.
Learn why short-circuit models can misrepresent inverter fault behavior, negative-sequence current, protection settings, and when EMT studies are needed.
