Abstract [en]

This paper describes the resonance introduced by adverse interaction of electronic converters. With the presence of multiple power-electronic converters, situations can occur where the harmonics are amplified due to the interaction between converters. An observation of undamped oscillation leading to instability in a microgrid is described. The term “converter induced resonances” is proposed to describe this phenomenon. The amount of distributed generation, active loads, FACTS and battery energy storage systems are expected to increase in future Smart Grids. All these resources will be interfaced with electronic converters. The potential impact of converter induced resonances in such grids is described. A coordinated design of the control systems of all converters is in practice not feasible. Each device will be independently tested to fulfil grid codes and have its own converter control implemented that can include functionality to modify voltage and /or current waveform.

Abstract [en]

There is a serious interest from the international standard-setting community in knowledge about voltage and current distortion in the frequency range 2 to 150 kHz, referred to as supraharmonics. At the same time, research is ongoing at a number of locations, but the knowledge about supraharmonics remains limited. This paper compares some of the properties of harmonics and supraharmonics. An increase in supraharmonics for individual devices is observed in association with a decrease in harmonic emission (i.e. below 2 kHz). A proposal is made for setting limits in this frequency range. The proposal is based on existing standards and is meant to be for discussion. The authors strongly encourage an open discussion about the proposed limits. There are a number of differences between harmonics and supraharmonics that are not covered by the proposed set of limits. A substantial amount of further research is needed to extend the standard framework for supraharmonics such that this can be covered by standards

Abstract [sv]

Byte till energisnål belysning är enligt flera forskningsstudier det mest kostnadseffektiva sättet att minska koldioxidutsläpp. Livslängden för belysning måste dock vara tillräckligt lång för att den minskade energianvändningen ska ha en ekonomisk fördel. Det är denna livslängd som ifrågasätts. Den begränsade hållfasthet ”immunitet” som belysning har mot störningar i spänningen kan vara en orsak till den minskade livslängden. Det behövs ny kunskap om detta förhållande för att kunna utveckla testmetoder, sätta gränsvärden på immunitet och kunna öka livslängden på belysningsinstallationer.

Abstract [sv]

Ett potentiellt hinder mot införandet av energisnål belysningsteknik är en förtätad användning av kraftelektronikbaserade ljuskällor eftersom dessa kan ge en alltför hög generering av ledningsbundna elektromagnetiska störningar. Målet med projektet är att kartlägga hur den elektromagnetiska störnivån förändras vid olika typer av installationsteknik, ökande antal störkällor mm. Delmål är att utveckla befintlig mätteknik och analysmetoder och studera olika elektronikkonstruktioner.

Abstract [en]

This paper presents the results from a number of measurements of the harmonic emission from installations that contain a large number of energy-efficient lamps. Two of the measurements concern the replacement of incandescent lamps with CFL and LED; the other measurement concerns an installation with up to 48 fluorescent lamps with high-frequency ballasts. The paper also contains a discussion on why the (total) power factor is not a good measure to quantify the performance of lamps or installations containing large numbers of lamps

Abstract [en]

This paper presents different methods to describe voltage and current distortion in the frequency range 2 to 150kHz. The time-frequency domain was shown to give additional information next to the time- and frequency-domain representations. Measurements of different devices and at different locations showed remnants of the switching frequency of the power electronics as well as lower frequency oscillations around the current zero crossing to be present in voltage and current. The voltage distortion is shown to vary a lot during the day and between locations.

Abstract [en]

The use of electric power has become a backbone of the modern society. Together with the growth in possible applications of electric power, we also see a growth in the number of devices and the interest of using electrical energy as an environmentally-friendly alternative to other sources of energy. Electrical equipment and the use of electricity develops towards more energy-efficient and high-technology products, This implies at the same time that the power quality is impacted as well. The accelerated use of power electronics, harmonics (LF harmonics, up to about 2 kHz) became an important subject for both engineers and researchers. This included origin, impact and propagation of harmonics. The existing situation is that HF harmonics (above 2 kHz) are taking over the role of LF harmonics as an area of concern in the power system as well as for end-user equipment. The driving forces behind the increasing levels of HF harmonics are the increased introduction of energy-efficient and high-technology products and, ironically enough, the limitation of LF harmonics among others using active converters. The research group at Luleå University of Technology, to which the author of this thesis belongs, is one of the few groups in the world that has studied different aspects of HF harmonics. A number of reasons have been identified for the lack of research on this subject: the fast development in technology; the lack of suitable measurement equipment; but most importantly the fact that this subject requires input from different engineering disciplines: electronics; electromagnetic compatibility (EMC); and power engineering. The last few years have however seen a fast growth in interest in the area, with several companies and universities contacting our group.The resonance phenomena, one of the main areas of concern for LF harmonics, are also a concern of HF harmonics but obviously at higher frequencies where experience and suitable measurement equipment was missing. Resonance phenomena in this frequency range have been identified by other researchers, but in relation to dc distribution or in relation to the testing of equipment. Common-mode resonance phenomena in the (ac) low-voltage distribution are treated in this thesis, whereas differential-mode resonances are studied in a parallel project.The aim of this thesis is to show the origin, propagation, impact and treatment of HF harmonics when modern equipment is connected to the low-voltage power distribution. The description is based on the existing knowledge on LF harmonics and the ongoing work, globally, on EMC, end-user equipment and power distribution.The title of the thesis "The zone concept - Design of low-voltage installations considering the spread of High- frequency harmonics" has been chosen to emphasize the need for electromagnetic compatibility and high power quality. This can only be achieved through interplay between end-user equipment and the electrical installation.An essential part in the zone concept is the limitation of the spread of HF harmonics through series filters, which may be power transformers, and through shunt elements to prevent high levels of disturbance especially due to resonances. Such shunt elements close the current path by lowering the impedance in the HF harmonic frequency range and can help in preventing resonance phenomena by introducing active losses. It is further shown in this thesis that many of the means to limit HF harmonics, e.g. transformers, can also be used to limit LF harmonics.
