Mitigation of Sub Synchronous Resonance by Static Compensator
With the aid of Fuzzy Logic Controller and Adaptive Neuro Fuzzy
Inference System Controller
Abstract:
Series compensation in lengthy transmission lines is a extreme solution to enhance power
transfer capacity of Power Program systems. However, utilization of series capacitors may cause
sub synchronous resonance (SSR) between electric and mechanical techniques. This
phenomenon may harm Creator generator base. Static compensator (STATCOM) is one of the
important Flexible ac transmitting techniques (FACTS) gadgets which uses to power factor
aspect, to regulate volts, to stabilize power circulation and to enhance the dynamic performance
of power techniques, moreover, it is able to provide effective remedy to damp the SSR, but it is
essential to add an reliable operator to the STATCOM for the objective of mitigating the SSR. In
this document, two controllers are included to STATCOM: Fuzzy Logic Controller (FLC) and
Adaptive Neuro fuzzy Inference System (ANFIS) and outcomes are in comparison.
Existing method:
In this method FACTS remotes are able to operate network conditions rapidly; moreover,
FACTs can be used to enhance power system balance. Currently, the most regularly used
FACTS system is the STATCOM. The STATCOM is depending on the principle that a voltage
source inverter (VSI) generates a manageable AC voltage source behind a transformer-leakage
reactance, so that the voltage difference across the reactance enhance power system balance by
treating sensitive energy to the transmission program. To successfully enhance the STATCOM
efficiency, past researchers mainly have targeted on its topology and control strategy.

Proposed method:
In this developed scheme, to damp the SSR; two auxiliary controllers are superimposed
on STATCOM one after another: fuzzy logic controllers (FLC) and Adaptive Neuro fuzzy
Inference system (ANFIS), in inclusion, outcomes are mentioned and in comparison. The FLC
has several advantages: having simple concepts because of easy statistical concepts which used
at fuzzy logic, being versatile, being able to identify mistake at nonlinear techniques with little or
no need for before details and can provide efficient control over a variety of system operating
situation.
