I have built an ETAP model of the IEEE 13-bus feeder with a PV source and completed a full protection-coordination study, yet the short-circuit module is returning unrealistic fault current values. Because those values feed directly into my relay settings, the time-current curves no longer prove CTI compliance, and the entire coordination becomes suspect. What I need urgently is a focused review of the fault-current simulation results themselves. Please examine the ETAP file and trace all assumptions affecting short-circuit levels, including source impedance, transformer impedance, line data, grounding, PV inverter contribution, breaker ratings, and any relevant study or calculation options. Then rerun the short-circuit study and identify the reason for the unrealistic values. If any parameters are incorrect, please point them out and correct them. If study settings or calculation selections are wrong, please revise them. If the issue arises from a modelling limitation in ETAP, please explain the limitation and suggest a practical workaround. Deliverables Cleaned-up ETAP model with corrected inputs and settings Short technical memo (PDF or Word) summarising the root cause of the unrealistic currents, the remedial steps taken, and any remaining limitations Updated relay coordination report demonstrating verified CTI values Clear screenshots or plots of the revised TCCs for quick cross-checking Once the base model and fault-current calculations have been corrected and validated, I would also like support with a limited penetration and mitigation assessment so I can get back on track quickly. Please run the corrected model at a few representative PV penetration levels, or in progressive steps if feasible, to help identify where protection miscoordination begins. At one penetration level where miscoordination is evident, please introduce and test a practical mitigation measure—preferably directional overcurrent relays (DOCRs), or another suitable protection adjustment—and show whether coordination can be restored. The aim of this extension is to give me a reliable technical starting point so I can continue the remaining simulations myself. I am working in ETAP 19.0.1, so please use that version or a fully compatible one. Time is critical, so please let me know how soon you could return a first pass once the file is received.

Your ETAP 19.0.1 IEEE 13-bus feeder model’s short-circuit analysis challenges demand a specialist who delivers precise, actionable corrections. With extensive expertise in power system protection studies and in-depth proficiency in ETAP modeling, I’ve resolved similar distortions affecting fault current accuracy and relay coordination integrity. Understanding your need for a thorough review—including verifying source and transformer impedances, grounding, inverter contributions, and study configurations—I will systematically audit all parameters and assumptions. I will refine the model, rerun fault-current simulations, and pinpoint causes of unrealistic values with technical clarity. Deliverables include a corrected ETAP file, a concise root-cause memo, updated relay coordination with verified CTI compliance, and clear TCC visuals for swift validation. Let’s start immediately; the worst that can happen is you walk away with a free consultation.

Before we start, are the unrealistic fault currents appearing mainly after adding the PV source, or even in the base IEEE 13-bus model? The main challenge here is accurately modeling fault contributions—especially from PV inverters—while keeping all impedances, grounding, and study settings consistent, otherwise ETAP can give misleading results. I’ve worked on similar distribution and DER-integrated studies where incorrect base values, transformer impedance scaling, or inverter assumptions caused unrealistic short-circuit outputs. In those cases, I traced issues to mismatched MVA bases, grounding configurations, and ETAP calculation settings. I’m comfortable reviewing the full ETAP model—source, transformer, line data, grounding, and study options—to pinpoint the exact cause. I’ll rerun the short-circuit analysis, correct any faulty inputs or settings, and clearly explain the root issue. Then I’ll update your relay coordination and TCCs to ensure CTI compliance is properly validated. For the extension, I can simulate PV penetration levels and apply mitigation (e.g., DOCR) to restore coordination. You’ll receive a clean ETAP file, technical memo, and updated plots/screenshots. I can deliver a solid first pass within 1–2 days after receiving your model.
