Overview

Most of the team's work was in this section. 

We simulated and studied different power rectifier circuit topologies (according to DIN 41761):

• B6C (three-phase controlled bridge), as part of converters for metallurgy, mining etc;

• M3.2C (six-phase controlled bridge), as part of converters for electrolysis;

• W3C (full controlled AC regulator), as part of softstarters for induction machines;

• IGBT  inverters / drives;

• other schematics (Static Var Compensator with TCR, 12- and 24-pulses rectifier ets);

 

Simulation goals:

• Simulation and study of electromagnetic and mechanical transients;

• Improve specifications and optimize system performance;

• Developing requirements for components of schematic;

• Fault conditions analysis;

• Developing requirements for control system action in fault conditions;

• Harmonic analysis;

 

Proof

Most of the simulation results have been embedded in the equimpent.

The simulation results were very close to the measurements (active/reactive power, voltage deviations, magnitudes of harmonics, THDu) at the plant.
