The commercial birth of the alternator (synchronous generator) can
be dated back to August 24, 1891. On that day, the first
large-scale demonstration of transmission of ac power was carried
out. The transmission extended from Lauffen, Germany, to Frankfurt,
about 110 miles away. The demonstration was carried out
during an international electrical exhibition in Frankfurt. This
demonstration was so convincing about the feasibility of
transmitting ac power over long distances, that the city of
Frankfurt adopted it for their first power plant, commissioned in
1894. This happened about one hundred and eight years before the
writing ofthis book (see Fig. 1.17).
The Lauffen-Frankfurt demonstration—and the consequent decision by
the city of Frankfurt to use alternating power delivery—were
instrumental in the adoption by New York’s Niagara Falls power
plant of the same technology. The Niagara Falls power plant became
operational in 1895. For all practical purposes
the great dc versus ac duel was over. Southern California Edison’s
history book reports that its Mill Creek hydro plant is the oldest
active polyphase (three-phase) plant in the United States. Located
in San Bernardino County, California, its first units went into
operation on September 7, 1893, placing it almost two years ahead
of the Niagara Falls project. One of those earlier units is still
preserved and displayed at the plant. It is interesting to note
that although tremendous development in machine ratings, insulation
components, and design procedures has occurred now for over one
hundred years, the basic constituents of the machine have remained
practically
unchanged.
The concept that a synchronous generator can be used as a motor
followed suit. Although Tesla’s induction motor replaced the
synchronous motor as the choice for the vast majority of electric
motor applications, synchronous generators remained the universal
machines of choice for the generation of electric power.
The world today is divided between countries generating their power
at 50 Hz and others (e.g., the United States) at 60 Hz. Additional
frequencies (e.g., 25 Hz) can still be found in some locations, but
they constitute the rare exception. Synchronous generators have
continuously grown in size over the years (see
Fig. 1.18). The justification is based on simple economies of
scale: the output THE SYNCHRONOUS MACHINE 19 rating of the machine
per unit of weight increases as the size of the unit increases.
Thus it is not uncommon to see machines with ratings reaching up to
1500 MVA, with the largest normally used in nuclear power stations.
Interestingly enough, the present ongoing shift from large steam
turbines as prime movers to more efficient gas turbines is
resulting in a reverse of the trend toward larger and larger
generators, at least for the time being. Transmission system
stability considerations also place an upper limit on the rating of
a single generator.
