Implementation of Kernel Incremental Metal earning Algorithm in
Distribution Static Compensator
Abstract
This dissertation presents achievement of Distribution Static Compensator (DSTATCOM) using
kernel incremental metal earning algorithm (KIMEL) control algorithm. It demonstrates the
functions of DSTATCOM such as reactive power compensation, harmonics elimination, load
balancing under linear and nonlinear loads with its self-supporting dc bus voltage. The proposed
control algorithm based on KIMEL is useful for extraction of fundamental active and reactive
power components of load currents which are required for inference of reference supply currents.
These reference supply currents are used for gating pulses generation using indirect current
control principle.
Existing method:
Not necessary to select exact internal parameter which is a main drawback of some other
conventional algorithms Conventional active filter Chen and Chen have described a
classification of various control algorithms for estimation of harmonics and their components.
Algorithms include PLL (Phase Lock Loop) based, ANN based algorithm, Kalman filtering etc.
Selection of a filter is decided by nonlinear behavior of loads in terms of crest factor, voltage
rating and current rating. Design of power circuit components and control algorithm is the key
issue of distribution static compensator (DSTATCOM) in the real time application.
Proposed method:
this dissertation a kernel incremental metal earning algorithm is implemented in shunt connected
compensating custom power device as DSTATCOM for extraction of active power and reactive
power current components of three phase linear and nonlinear loads. Proposed control algorithm
is used for reactive power compensation, harmonics suppression and load balancing with self
supporting features of dc bus voltage. Advantages of this algorithm is that it has only two
internal parameters as metal earning rate (θ) and the forgetting factor(λ), which have wide

ranges for choice to produce desired response. It is less sensitive due to variation of metal
earning rate and the forgetting factor and adaptive in nature.

This project developed in Matlab/simlink soft ware and the results have been studied.
Advantages:
1) Future control algorithm is used for reactive power compensation, harmonics suppression and
load balancing with self supporting features of dc bus voltage.
2) Advantages of this algorithm is that it has only two internal parameters as metal earning rate
(θ) and the forgetting factor (λ), which have wide ranges for choice to produce desired response.
It is less sensitive due to variation of metal earning rate and the forgetting factor and adaptive in
nature.
Applications:
1) The future method used in nonlinearity supply systems nonlinear behavior of connected loads
is the main reason of harmonics distortion in the supply voltage and currents these will be
modify this problems.
2) The area of power quality mitigation, active filers have taken sufficient lead to mitigate
electrical power quality disturbances such as harmonics suppression and reactive power
compensation in the supply system.
