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.
