Description:
The Transmission Line Simulator investigates single-phase and three-phase transmission lines. The configurable simulated transmission lines allow realistic studies of short, medium and long-distance transmission lines under variable load and power factor conditions, as well as with inserted faults. The console is divided into two control panels, each with detailed mimic diagrams. The upper panel has a single phase transmission line equivalent circuit, and the lower panel a three-phase transmission line. The lines may be loaded by the resistive, capacitive and inductive loads included. The effects can be monitored by instruments at the send and receive ends of the transmission lines.
Learning Outcomes
- Single-phase line:
- Short-line investigation
- Medium or long-line investigation (nominal ‘Tee’ and ‘Pi’ methods)
- Effect of power and reactive power flow on voltage drop and transmission angle
- Medium/long-line investigation of a natural load of a line
- Voltage regulation at constant load and power factor Three-phase lines:
- Per-unit values
- Unbalanced loads and the neutral connection
- Fault simulation and line protection studies
- Parallel feeders and multi-section lines
