PROBLEM TO BE SOLVED: To continue operation of a generator by automatically selecting and cutting off a load even at accident time of a boiler or steam piping. SOLUTION: In private power generation equipment which has a steam turbine power generation equipment of constant pressure operation and supplies its generator output to plural feeders whose priority order is determined, a pressure detector 9 is arranged to detect turbine inlet steam pressure, and its detecting value is inputted to a computing element 10 together with the generator output and detecting values of load electric power of the respective feeders 5 to 5n. The computing element 10 is provided with a function of issuing a circuit breaker tripping command for the feeders by performing prescribed operation processing using a turbine maximum output possible curve as a basis by using the detecting value of the pressure detector 9 and the respective electric power detecting values as input. |
