Abstract:
Disclosed are a power plant that uses a synchronous generator using a working fluid for generation of electric power, and a method of controlling the power plant, the power plant and the control method having an advantage of preventing damage to the power plant during synchronization with an electrical grid. The power plant comprises a pump for compressing a working fluid, a heat exchanger for heat transfer from an external heat source to the working fluid transferred from the pump, and a power turbine generator for generating a rotational force by using the working fluid heated by the heat exchanger, generating electricity using the rotational force, and supplying the electricity to an electrical grid.

Claim (Index 1):
A power plant comprising:\n a pump configured to compress a working fluid; a heat exchanger apparatus configured to cause heat exchange between the working fluid transferred from the pump and an external heat source; a power turbine generator configured to generate a rotational force by using the working fluid heated through the heat exchange performed in the heat exchanger apparatus, to generate electricity using the rotational force, and to supply the electricity to an electrical grid; a condenser configured to cool the working fluid discharged from the power turbine generator; a working fluid supply line connected to the heat exchanger apparatus and the power turbine generator at respective ends thereof to provide a flow path from the heat exchanger apparatus to the power turbine generator for the working fluid discharged from the heat exchanger apparatus; a pressure sensor installed on the working fluid supply line and configured to measure a pressure of the working fluid supplied to the power turbine generator; a working fluid recovery line connected to the power turbine generator and the condenser at respective ends thereof to provide a flow path from the power turbine generator to the condenser for the working fluid; a bypass line connected to the working fluid supply line and the working fluid recovery line at respective ends thereof to cause a portion of the working fluid flowing through the working fluid supply line to bypass the power turbine generator and to directly flow to the working fluid recovery line; a first control valve installed on the working fluid supply line and configured to control a flow rate of the working fluid flowing through the working fluid supply line; a second control valve installed on the bypass line and configured to control a flow rate of the working fluid flowing through the bypass line; and a controller configured to control the first control valve and the second control valve according to the measurement value of the pressure sensor and an operational state of the power turbine generator.
