Welcome to Keentel Engineering. Here, we answer your most pressing questions about power flow analysis—what it is, why it matters, which software we use (ETAP, PSS®E, PowerWorld), data requirements, deliverables, and how often studies should be refreshed. Dive in to get expert guidance for optimizing your high- and medium-voltage networks.

Frequently Asked Questions (FAQ)

Q1: What is a Load Flow Study?

A Load Flow Study (or power flow analysis) evaluates the steady-state operation of an electrical network, calculating voltages, active/reactive power flows, and system losses to ensure voltage stability and efficient power delivery.

Q2: Why are Load Flow Studies essential for HV/MV systems?

They help you:

  • Verify voltage compliance with ANSI/IEC standards
  • Optimize conductor sizing and transformer tap settings
  • Prevent overloads and voltage drops
  • Support protection coordination, arc-flash, and short-circuit studies
  • Plan for future DER or renewable integrations

Q3: Which software platforms do you use?

We leverage ETAP, Siemens PSS®E, and PowerWorld for scalable, high-fidelity simulations across HV and MV networks.

Q4: What data does Keentel need to begin?

  • Single-Line Diagrams (SLDs)
  • Bus & line impedance, length, ampacity
  • Transformer and generator specs
  • Load profiles (kW/kVAR)
  • Renewable resource data (PV, wind, BESS)
  • Contingency and switching scenarios

Q5: What are the typical deliverables?

Our detailed report includes:

  • Bus voltage profiles
  • Branch power flows & losses
  • Transformer loading & recommended tap settings
  • Color-coded one-line diagrams
  • System efficiency metrics
  • Actionable improvement recommendations

Q6: How often should studies be refreshed?

Update whenever you add major loads/generation or reconfigure the network—and at least every 3–5 years for critical or NERC-jurisdictional facilities.

Q7: Do you handle renewable interconnection studies?

Yes. We perform load flow analysis for solar, wind, and utility-scale BESS interconnections, ensuring compliance with ISO and utility requirements.

Q8: Are load flow studies required for permitting?

Often—utilities, ISOs, and permitting bodies typically mandate power flow analysis for grid impact assessments and interconnection approvals.

Q9: Can load flow be integrated with other studies?

Absolutely. We bundle Load Flow with Short-Circuit, Protection Coordination, Arc-Flash, Harmonics, and Stability analyses for turnkey project support.
