| Most of
the research at IEA is application oriented, where each
program and project has been inspired by some real industrial
problem. This has made it necessary to find networking
of different competences to solve the specific research
task. Our goal is to be industrially relevant as well
as academically and internationally competitive. There
are several important advantages of founding a research
program in this way. Electrical
drive systems offer a combination of problems in
control structures, very fast digital control, power
electronics and machine design and operation. In electrical
power systems the emphasis has been put on distribution
automation, where control, computer engineering and
power systems technology (including power electronics)
have to be integrated. In automation
the emphasis is on the control of industrial processes,
where control theory, real time computing, electronics
and sensor technology are combined.
Projects:
EU-DEEP
EU-projekt inom sjätte
ramprogrammet med mål att främja distribuerad
generering (DG), dvs småskalig elproduktion, i
Europa. Kombinerad produktion av el och värme utgör
ett viktigt alternativ till fossileldade kraftverk som
endast ger el kan stora miljövinster göras
genom förbättrad verkningsgrad. Initiativtagare
är åtta energibolag som genom sina kundregister
bidrar till att finna marknadssegment där DG är
lönsamt. Målet är storskalig introduktion
av DG genom ”market-pull” snarare än
”technology-push”. Delprojekten där
IEA deltar är rent tekniska och behandlar dels
ödrift, dels styrning av små kraftverk, ofta
anslutna till elnätet via kraftelektroniska omvandlare.
Ödrift innebär självständig drift
av lokala elnät matade av småskaliga kraftverk,
vilket är värdefullt under störningar
i kraftsystemet och har viktiga beredskapsaspekter.

BAS
- Belt driven Alternator and Starter
The rather old idea combining the
starter and alternator into one electric machine but
also implementing light hybridization and utilizing
the machine type called Series Magnetized Synchronous
Machine, SMSM. The machine type SMSM is newly developed
and much effort is focused on learning to control this
type of machine. The machine is analyzed in depth both
theoretically (electric, magnetic and mechanic modelling)
and practically. Modelling in the simulation environment
Simulink, Matlab is performed. The physical structure
and shape of the machine is further analyzed using the
Finite Element Method (FEM) for optimization. Simulations
on vehicle level is performed for optimizing i.e. the
fuel consumption and achieving an approximate size of
the electric machine.

SAAB-HYBRID
The purpose of the project is aimed to increase the
knowledge in the area of vehicle- and drive-train architecture
further more investigate the influences on fuel-consumption,
emissions and performance with an optimized system of
combustion engine, electrical motors and drive train
control system. The potential in hybrid drive system
technology for vehicle is in optimal balancing of the
size and properties of the traction sources, the control
strategies, the topology and not least the properties
and use of the energy storage system. LTH has long experince
of system optimization for hybrid traction systems.
The proposed project is dedicated to application and
development of existing "state of the art"
knowledge on system optimization of a high performance
hybrid vehicle developed by Saab Automobile. Key technology
developed by LTH for charge balancing of traction batteries
will be applied and evaluated.

Det som studeras är möjligheterna
att utveckla en ny produktionsmetod för små
elmotorer som används i en mängd tillämpningar
i stora volymer. Metoden som skall studeras är
formgjutning av de aktiva delarna i motorn. Stora möjligheter
till förenklingar/integrationer och kostnadsreduktioner
finns. Målen är förutom att undersöka
konstruktions-/produktionslösningar att bygga två
oberoende prototyper för att demonstrera teknologin.
Fyra olika företag och två institutioner
inom Lunds Universitet samarbetar.

Interdependenser
mellan tekniska infrastrukturer
Elnätet och telenät tillhör
samhällets viktigaste infrastrukturer och de senaste
åren har även datorkommunikationssystem kommit
att räknas dit. Dessa system har i hög grad
utformats för att vara robusta och tåla störningar
i vissa delar utan att deras funktion i stort påverkas.
Större påfrestningar såsom stormen
Gudrun i januari 2005 visar dock att systemen beror
av varandra ibland i högre grad än vad som
är lämpligt. IEA driver ett delprojekt om
detta inom ramen för forskningsprogrammet FRIVA
(Framework programme Risk and vulnerability analysis
of technological and social systems). Detta är
Krisberedskapsmyndighetens ramprogram för att bygga
upp nationell kompetens inom risk- och sårbarhetsanalys
som grund för samhällets krisberedskap. Programmet
är tvärvetenskapligt och bedrivs inom LUCRAM
(Lund University Center for Risk Analysis and Management).

In a joint collaboration between Denmark and Sweden
the goal of this project is to increase the capacity and
improve the operation of wastewater treatment plants in full scale.
The work focusses on practical aspects and technologies available today
and rely on on-line control, modern sensors and computer models.
The main partners are Avedore Wastewater Services Company (coordinator, Denmark),
Lynettefallesskabet I/S (Denmark) and Malmoe Water Works (Sweden).
A number of experts and consultants are also directly involved to support the research.
In addition to IEA, the dept of Chemical Engineering (Lund University), Krüger A/S (Denmark)
and Hach Lange APS (Denmark) are active. More information can be found on the temporary

Benchmark
On behalf of the International Water Association (IWA)
an international Task Group has been established to develop and promote
a general protocol for objective comparisons of control strategies for wastewater
treatment plants. The protocol involves process models, simulation procedures,
evaluation criteria and influent data among other things to allow control
strategies to be evaluated in a uniform way. Work is also done to allow for
process monitoring procedures to be evaluated by similar principles. Three
systems are being developed for multiple simulation platforms: Benchmark Simulation
Model no 1 (BSM1) for short-term control strategy evaluation of the activated
sludge (AS) process; BSM1_LT for long-term evaluation of monitoring procedures in AS
systems; BSM2 for long-term control strategy evaluation of plant-wide systems
including sludge treatment. The work was initiated within the EU COST Actions 624
and 682 and the IWA Task Group on Respirometry in Control of the AS system.
The other members of the task group are: prof Peter Vanrolleghem (Canada), Dr Marie-Noelle
Pons (France), prof Jean-Philippe Steyer (France), Dr John Copp (Canada), Dr Jens Alex
(Germany) and Dr Krist Gernaey (Denmark). More information may be found at the

Sedimentation
The sedimentation process is often the weakest link
in wastewater treatment plant operation. It is today controlled mostly by the
experience of operators since no advanced controllers exist. Improved control is of great practical,
economical and environmental value. During the 1990s, a new mathmatical
model was developed by Dr Stefan Diehl (Mathematics Centre, LU) capable of
describing the complex nonlinear
behaviour of the settling process in greater detail.
In this project, the possibilities to apply this new model and enhance on-line
control capabilities is investigated. The project is a joint effort between the
Mathematics Centre (Lund University) and IEA. Coordinator is Dr Stefan Diehl.

system restoration with distributed generation
The goal of this project
is to investigate the impact of distributed generation
on power system restoration. Distributed generation
can make restoration both easier or harder depending
on situation and restoration plan. This will be investigated
using extensive simulations of restoration sequences
and automatic search methods to find restoration sequences.
The simulations will include positive sequence repetitive
loadflow with the models for cold load pick up, start
time and ramping for different generation units, including
the degree of controllability. The restoration sequences
will be simulated on different levels of the power system
from 10 kV to 400 kV. A interesting question are how
many islands that should be started.
