Study of (D-STATCOM)‎ impact in a grid connected (SCWEG)‎ under symmetrical fault

Abstract EN

This paper provides an optimized (Distributed STATCOM) control for wind electric
generator.

The transient behavior of squirrel cage wind electric generator (SCWEG) can be
improved by injecting large amounts of reactive component during the fault recovery.

This
System requires a high dynamic converter, which able to work under abnormal conditions.

The reactive power demand, which is necessary for fixed- speed wind turbine system
(FSWTS) during faults is not met by capacitor banks installed near (SCWEG).

This paper
analyzes the impact of (D- STATCOM) in a grid connected (SCWEG) under fault and offers
study of the whole performance of the system which can be improved by means of
Distributed Static Synchronous Compensator (D-STATCOM).

It is used for restoring the
voltage at generator terminals under fault conditions was occurred.

Simulation was carried out
by MATLAB SIMULINK under abnormal conditions.

Both real and reactive powers confirm
that the (D- STATCOM) has good performance with (SCWEG), and the voltage profile is
improved, the stability is increased and the performance of the complete system is improved.
