1. 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.
