Max Blatter, graduate electrical engineerSymphony of Electric Power Systems Further details of my musical knowledge?– There aren’t any, it’s as easy as that! I already mentioned that I am interested in music; but musical knowledge is limited to the music lessons at school and a few years of transverse flute lessons as an adult (the flute has been sold meanwhile). Reading music? Well ... it’s a bit like a dyslexic reading a text! At least, this is true when I am to sing an unknown melody just sight-reading (or, vice versa, when I try to write down a melody that I just improvised by singing – there will be an example just some slides later). As concerns the transverse flute, I used to turn the notes of unknown pieces into fingering rather than into inwardly heard tones. Still, I am hardly able to hear music in my own home without singing along or trying to sing it by heart, and sometimes improvise additional voices or counterpoints! And I used to sing in the choir of a Rudolf Steiner School at some occasions as well. But anyway: It should have become clear why I am seeking to cooperate with professional musicians! Not only because of the availability of a professional studio equipment, but also because of their know-how. continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems When power systems themselves make music – example 1 Sometimes, electric power systems themselves are producing a sort of music without someone having to do something for it. I integrated two examples in the script of my learning module „Power Systems“ that I am teaching within the bachelor’s degree course “Engineering and Management” at the School of Engineering FHNW in Windisch, Switzerland. I did this long before I had the idea of turning the entire technology of power systems into music! To explain, I must reach back a bit:There are some special “deepening exercises” scattered in my script, where the fictional siblings “Winga” and “Wingo” occur as protagonists. (They are named after the German name of the bachelor’s degree course, “Wirtschaftsingenieurwesen”, abbreviated „WIng“.) Can it be a pure coincidence that Winga maintains music as a passionate hobby and is the lead singer of a rock band ...? But let us proceed to the first example: continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems When power systems themselves make music – example 1Summary The example just shown is based on the fact that an imbalance between production and consumption leads to frequency variations in the interconnected grid, which could in principle be audible if they only are large enough. From a technical point of view, such imbalances must be compensated within seconds, which normally works very well thanks to the automatic control. continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems When power systems themselves make music – example 2 A second example arises when a special sort of electrical engine – usually a so-called induction engine – is driven by a frequency converter. Such a converter produces by pulse width modulation what could be called an artificial synthesis of an AC voltage, whose frequency can be varied continuously. But normally, this frequency is quite low and lies even in the infrasound range during start-up; so it is hardly audible. In contrast, the pulse frequency usually lies in a well audible frequency range, at least in case of railway drives (several hundred Hertz). It stays constant over the entire operating range, except for rare cases where ... but see for yourself: continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems Musical metaphors in power systems – example 1 Most often, however, we must resort to something which I call a “musical metaphor” in the context of this project: If we want to turn the physical or mathematical properties of power systems into music, we have to do so by making up analogies. The following examples are all related to one of the most important concepts in the technology of power systems: to the concept of three-phase alternating voltage. continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems Musical Metaphor 1The three-phase AC system as a dissonant triad c-e-g# continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems Musical metaphors in power systems – example 1Explanation In a three-phase AC system, there are three sinusoidal AC voltages, which have both the same amplitude and the same frequency (namely, throughout Europe, 50 Hz). However, they are time-shifted by a third period – the expert speaks of a phase shift of 120° from phase to phase. Therefore, these voltages are also called the three phase voltages: Phase 1, phase 2, phase 3. After phase 3, phase 1 follows again – the whole thing continues infinitely. continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems Musical metaphors in power systems – example 1Explanation Now, the musical metaphor symbolizes the three phases by individual tones. Two properties of the phase voltages are adopted by the metaphor: a)The three phases should be “equidistant”. Thereby means:“distance” in the real world = phase shift (120°);“distance” in the metaphor = interval between the tone pitches.Thus, the interval between two succeeding “phases” should always be the same – but which? b)The infinite cyclic repetition in the real world should also be reflected in the metaphor – but how? continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems Musical metaphors in power systems – example 1Explanation We get a grip on both points by choosing the major third as the interval in question. If we model phase 1 by the tone c, for example, then e follows as the representative of phase 2 and g# is representing phase 3. An other major third leads then to c’ – indeed, the circle closes an octave higher. – This augmented triad (I found the term in a small German booklet on music theory and its English translation in Wikipedia) happens to be dissonant – so be it: Life’s no bowl of cherries, and anyway, not all sounds can be harmonious (we all know that music – from classics to progressive rock – actually lives from exciting dissonances and the resulting desire of relaxing resolution)! continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems Musical metaphors in power systems – example 1Explanation In order to really get an infinite cycle, let’s add overtones! In this matter, I let myself inspire by a broadcast on electronic music, which I heard in my teens or twenties. A sound was presented there that once sounded like an infinite upwards and then like an infinite downwards glissando, but whose overall “pitch” remained constant. – In fact, the sound really was a glissando, which however passed a filter having a steady filter curve. If we are mixing the tones of the two octaves C to c and c to c’ as suggested in the PowerPoint presentation, then we can indeed see (and hopefully also hear) the c representing phase 1 in two ways: either below the e of phase 2 or above the G# of phase 3. (Probably, the thing has still to be optimized, especially what concerns the filter curve.) continue →

Max Blatter, graduate electrical engineerSymphony of Electric Power Systems Musical metaphors in power systems – example 2 The representation of the three phase voltages as shown in “metaphor 1”, is a purely static one. After all, it is in my opinion only a basic element with which we should continue to work. Like that, for example: continue →
