PROBLEM TO BE SOLVED: To make it possible to automatically and promptly actuate sound generators if a total service interruption occurs due to the accidental shutdown of one generator. SOLUTION: A power plant in normal service operates a plurality of generators G1 -GN in parallel and supplies feeders F1 -FN with the output of the generators through a bus B. The power plant is provided with means WTT and MT for measuring and storing at least the total amount of load power so that, if a total service interruption takes place, generators in the number equivalent to the amount of power immediately before the total service interruption will be automatically actuated. In addition, the power plant is provided with means WT1 -WTN and WTT for measuring and storing the amount of power of each feeder F1 -FN, and prioritization for actuation is made. Thus control is exerted so that the total capacity of operated generators will not be exceeded. |
