Abstract

This power generation system (20A) includes a plurality of power generation units (50A, 50B, 50C, . . . ) which are provided in parallel, wherein each of the power generation units (50A, 50B, 50C, . . . ) includes an expander (26) configured to be rotated by a working medium, a power generator (28) configured to generate power through rotation of the expander (26), a rectifier (29), a medium circulation system (22) configured to pump the working medium into the expander (26), a relay (70) configured to interrupt power between the power generator (28) and an external power system (30), an operating unit (40A, 40B) configured to be operated when maintenance starts, and a relay driving unit (71) configured to interrupt power between the power generator (28) and the external power system (30) by the relay (70) when the operating unit (40A, 40B) has been operated.

Claims9

Dependent claims

A power generation system comprising a plurality of power generation units which are provided in parallel to an external power system,

wherein each of the power generation units comprises:
an expander configured to be rotated by a working medium;
a power generator configured to generate power through the rotation of the expander;
a rectifier configured to rectify the power generated by the power generator and output the rectified power to the external power system;
a medium distribution system configured to pump the working medium into the expander;
a relay configured to interrupt power between the power generator and the external power system;
an operating unit configured to be operated when maintenance of the power generation unit starts;
and
a relay driving unit configured to interrupt power between the power generator and the external power system by the relay based on an operation state in which the operating unit has been operated.
