摘要： PURPOSE:To reduce a power receiving system capacity from a commercial power system by connecting a flywheel generating system in parallel to a private power generating system and performing combined operation therewith. CONSTITUTION:In a flywheel generating system 8, a generator motor(G/M)9 is used for both a generator(at power generation time) and an electric motor(at power accumulation time). That is, input power from a power converter Pc11 is accumulated as rotational energy in a G/M rotational part and a flywheel 10, directly coupled to the G/M rotational part, by operating first the G/M9 as the electric motor at the power accumulation time. On the other hand, power is supplied by converting the rotational energy into electric energy, by functioning the G/M9 as the generator at the power generation time. In this way, peak power, received from a system bus bar 2, can be reduced.

When power supply to the load 1 from the fly-wheel generator 2 is completed, then from the fly-wheel generator 13, power is fed to the load 1 via a transformer 15 and the power converter 3. As a result, the power can be supplied to the load 1 continuously or almost continuously.

摘要： PURPOSE:To derive a current value of one branch, accordingly, to reduce the number of current transformers by one, by executing a prescribed operation by use of a current value of other branch and a total current value. CONSTITUTION:Current transformers 2a-2c are installed to three branches having rectifier banks 1a-1c, respectively, among four branches having rectifier banks 1a-1d, but no current transformer is provided on the branch having the rectifier bank 1d.
