| Abstract: |
| In this paper, we present a detailed procedure to determine the semiconductor losses for both structures of a
shunt STATCOM (Static Compensator), STATCOM based on Current Source Inverter (CSI) and STATCOM based on
Voltage Source Inverter (VSI), both used for voltage unbalance compensation. As a first step, we study the VSI-based
STATCOM and the CSI-based STATCOM used in high speed railway substations. Then we analyze the design and
the sizing of the unbalance compensator in order to obtain an unbalance factor that does not exceed the limits
imposed by the standards or by the energy provider. Following that, we compare the performances obtained with
both structures VSI-STATCOM and CSI-STATCOM, after calculating the semiconductor power losses in the STATCOM
converters. Finally, we validate our approach by simulation over real data of unbalance compensation caused by
the new high-speed railway in Morocco. We use the tools MATLAB / Simulink/Simpowersys for performing our
simulations. |
