Power System with a Transmission Line operating at low frequency

Description:
Demonstration of the operation of a power system with a transmission line in low frequency. This model contains a 5-bus power system with a transmission line operated at a frequency of 41Hz.
The ... see moresystem includes:
- Model of frequency converters (averaged model of the Modular Multilevel Matrix Converter, MMMC).
- Converters control schemes.
- Initialization branches to include the low frequency line in the steady-state calculation.
- Internal variables of the converters such as voltages in the storage capacitors, branch currents, internal voltages, among others, can be plotted.
- External variables to the converters such as power flow in the low frequency line, currents and voltages can also be plotted.

AC and DC components meter

Description:
This example contains a device which calculates the DC and AC components.
- The DC component is available in the DC control scope with half
a cycle delay versus the simulation time
- ... see moreThe AC component is available in the DC control scope with one
cycle delay versus the simulation time

Once the maximum DC magnitude is reached, the time constant is
determined assuming the DC decay is exponential and uninterrupted

Active Harmonic Filter

Description:
The shunt filter injects the current that is defined as the error between the (non-linear) load current and the fundamental harmonic. The filter uses a 3-level inverter and the 2-level hysteresis curr... see moreent control.
