Load Flow Analysis

Load flow analysis tells you whether your network holds up under the conditions it will actually be operated in — not just the design case. It underpins equipment sizing, voltage compliance and every study that follows.

What this covers

  • Voltage profile — bus voltages across normal, peak, minimum and contingency operating cases.
  • Equipment loading — transformer, cable and busbar loading against continuous and emergency ratings.
  • Reactive power and power factor — reactive flow, compensation requirements and capacitor bank sizing.
  • Transformer tap settings — fixed and on-load tap changer ranges to hold voltage within limits.
  • Contingency cases — network behaviour with a transformer or feeder out of service.
  • Losses — where real power is being lost and what it costs over an operating year.

What you receive

  • Load flow study report covering each operating case
  • Validated network model handed over for future use
  • Voltage profile and loading summary tables with exceedances flagged
  • Recommendations on tap settings, compensation and any reinforcement needed

Standards and references

Studies are prepared with reference to IEEE 399 for industrial power system analysis and IEC 60038 for standard voltage limits, alongside the applicable grid code.
