For example,if there is enough water flowing in the river to permitthe operation of one machine at full load and to produce100 kw. on another, full use can be made of the wateravailable and of the full capacity of the windings onthe second machine, by taking the control away fromthe contact-making ammeter and using the under-loaded, over-excited machine to absorb a large part ofthe wattless component of the system load.

Special Features of the Layout The general arrangement of the power house and itslocation with respect to the river are not unusual. Theinterest in the plant lies principally in the selection andarrangement of the electric automatic control appara-tus. Each machine with its water wheel and motor-driven control of the gate opening, and its electric con-trol relays and contactors, form a completely separate IOWA AUTOMATIC HYDROELECTRIC PLANT FRONT ENTRANCE.
