Abstract

PROBLEM TO BE SOLVED: To provide a frequency-converting power generating equipment which can suppress heat generated due to a load from harmonics in a power supply and suppress the increase of a contract demand as low as possible. SOLUTION: A mechanical drive apparatus 7 and a motor-driven drive apparatus 6 driven by a 60 Hz power supply system 1 are connected in parallel with a generator 5 via a connection mechanism 5a for driving the generator 5. The generator 5 is driven by both the driving apparatuses 6 and 7 and generates 50 Hz power to drive to 50 Hz load 8. The mechanical drive apparatus 7 outputs a constant output P. With the maximum output P of the motor-driven drive apparatus 6, the generator 5 can supply a maximum output 2P to the load 8. Further, if the output is negative, the motor-driven drive apparatus 6 functions as a generator and power corresponding to the negative output is transmitted to the 60 Hz power supply system 1.
