The Power Engineering
Chapter, together with the Nanyang Technological University (NTU), is
pleased to organize a technical seminar on the research of Power Line
Communication Network and Unified Power Quality Conditioner. Below are the
details of the seminar.
Title (1):
Modeling of Radio Frequency Electromagnetic
Disturbances
in Power Line Communication Networks
Date: Wednesday, June 25th, 2008
Time: 3:00 p.m
Venue: NTU
EEE Executive Seminar Room
S2.2 B2-53
Presenter: Mr. Pang Teng Seng
Abstract:
This seminar will cover a new approach to modeling the radio frequency
(RF) electromagnetic disturbances in broadband power line communication
(PLC) networks using the multi-conductor transmission line (MTL) theory.
The model includes a differential-mode (DM) current propagation model
and a common-mode (CM) current propagation model. The frequency range of
interest is from 1MHz to 30MHz. Practical measurements are carried out
to compare with the simulation results as a form of verification of the
accuracy of the proposed models.

(EMI/EMC) design issues in power line communication networks.
Title (2): Unified Power Quality Conditioners:
A Model-Based Control via H∞ Loop-Shaping
Date: Wednesday, June 25th, 2008
Time:
3:30 p.m
Venue:
As above
Presenter: Mr. Kwan Kian Hoong
Abstract:
A Unified Power Quality Conditioner (UPQC), an integration of the shunt
and series active filter, can be installed in power systems to overcome
a host of power quality (PQ) problems. Traditional control techniques
neglect the coupling effects between the two filters and their
impedances, while model-based control techniques, that can handle the
coupling effects, may be complex and costly to be implemented. Any
modelling error can be detrimental to the control and operation of the
UPQC too.
In this research, a model-based feedforward (FFC)/ feedback (FBC)
control technique that combines the multivariable regulator theory and
the H-infinity is proposed for the UPQC to overcome a host of PQ
problems. Zero steady state error can be guaranteed by the FFC in the
absence of modelling error, while the complementary FBC seeks to
mitigate the negative effects of any modelling error. This technique
also seeks to reduce implementation complexity and cost.
