Essential Electrical Modeling Techniques

Apply Simscape™ modeling rules when you build electronic, mechatronic, and electrical power system networks usingSimscape Electrical™.

Three-Phase Ports

Connect three-phase blocks using composite ports for three-phase lines or expanded ports for single-phase lines.

Featured Examples

LC Transmission Line and Test Bridge

A transmission line model and bi-directional test bridge. Reflected and transmitted signals are slightly different if the test direction is changed. This is because the line model is not symmetric. This type of model can be used both to explore the impact of cable choice on transmission characteristics, and also to compare relative fidelity of different transmission line model structures and parameterizations.

Asynchronous Machine Direct Torque Control

Control an asynchronous machine (ASM) using the direct-torque control method. A PI-based speed controller supplies the torque reference. The direct-torque controller generates the inverter pulses.

Three-Phase Asynchronous Machine Starting

Model a wye-delta starting circuit for an induction machine. When the supply is connected to the machine via switch S1, switch S2 is initially off resulting in the machine being connected in a wye configuration. Once the machine is close to synchronous speed, switch S2 is operated thereby reconnecting the machine in a delta configuration. The higher impedance seen by the supply when the motor is in wye configuration reduces the starting current, and causes less disruption to other connected loads.
