Abstract

A power generation system has a fuel cell, a gas turbine, an exhausted oxidant line, a fuel gas supply line, an exhausted fuel gas supply line, a supply amount adjustment unit, and a control system including an information acquisition unit, a calculation unit, and a fuel gas supply control unit. The information acquisition unit acquires an output command of the gas turbine, an atmospheric temperature, a temperature of the exhausted oxidant supplied to the gas turbine, and a temperature of the exhausted fuel gas supplied to the gas turbine. The calculation unit calculates a heat input of the exhausted oxidant, calculates a heat input of the exhausted fuel gas, and calculates by the output command and the atmospheric temperature to calculate a gas turbine heat input command.

First claim

The invention claimed is:

1. A power generation system comprising:
a fuel cell;
a gas turbine including a combustor;
an exhausted oxidant line that supplies exhausted oxidant from the fuel cell to the combustor;
a fuel gas supply line that supplies fuel gas to the combustor;
an exhausted fuel gas supply line that directly supplies exhausted fuel gas from the fuel cell to the combustor;
a supply amount adjustment unit that adjust an amount of the fuel gas supplied from th…
