DC Capacitor and Battery based Voltage Balancing Control for Cascaded H-Bridge STATCOM with Edmonds’ Algorithm
Abstract
This project deals with enhancing the
voltage quality from voltage sags and one more power
quality issues are rectifying in this project that is a
harmonics. The level of the inverter is increased for
accurate system performance. The system has more stable
by proposed Edmonds’ algorithm and its used for finding a
spanning dendri form of minimum weight (sometimes
called optimum branching). Its an directed analog of the
minimum spanning tree problem. This algorithm is faster
implementation and less number of iterations compared
with other algorithms. This algorithm to produce a delta
signal for controlling the space vector pulse width
modulation signal because the SVPWM has only produce in
the static frequency so lightly harmonics are produced so
the quality of the power is reduced. That harmonics are
reduced by using the variable frequency is produced by
algorithm.
The STATCOM is used in fifteen level inverters for
better performance its reduce a generation of harmonics and
it get a dc sources from capacitor banks and battery banks
because this store a huge amount of energy compared with
capacitor banks. A simulation model based on this method
is built in the MATLAB platform. The simulation results
show that, the proposed control algorithm can make sure
STATCOM precisely and quickly compensate reactive
power, improve the power factor, stabilize the DC voltage sag and compensate the voltage sag and reduce the
generation of harmonics.
