A turbine output is obtained by adding the steam turbine output to a gas turbine output. A power generator output is subtracted from the turbine output. A remote load interruption detector 25-1 detects the power-load unbalance when deviation between the turbine output and the power generator output exceeds a previously set prescribed value.
