    Abstract: To provide an interconnecting power generation system which can detect an abnormality in the utility power supply and can be isolated from a utility power system (10) and can prevent damage to a turbogenerator. An interconnecting power generation system comprises: an interconnecting inverter (14); a voltage phase shift circuit (20) which synchronizes the output voltage phase of the interconnecting inverter (14) with the utility power voltage phase and monitors zero crossings of the utility power voltage, and which shifts the output voltage phase from the utility power voltage phase and shifts the shifted output voltage phase to the utility power voltage phase; a phase comparator (24) for comparing the voltage phase of the utility power system (10) and the output voltage phase of the interconnecting inverter; and an interconnection control unit (30) which detects a power outage caused by an interruption of power supply from the utility power system (10) based on a series of a predetermined number of matching signals outputted from the phase comparator (24) and sends a control signal to a circuit breaker (22) to shut off the output of the interconnecting inverter (14) from the utility power system (10).

    Abstract: A gas turbine apparatus is provided wherein a turbine is driven or rotated by burning a mixture of a fuel and compressed air and supplying a combustion gas generated by the combustion. A flameout determination unit is provided in the apparatus which is adapted to calculate the air/fuel ratio in the air/fuel mixture, correct the calculated air/fuel ratio to calculate a corrected air/fuel ratio which is substantially constant, compare the calculated corrected air/fuel ratio with a predetermined reference air/fuel ratio, and generate a signal indicative of occurrence of a flameout when the corrected air/fuel ratio is smaller than the reference air/fuel ratio. The corrected air/fuel ratio is calculated by calculating a deviation of a compressor discharge pressure of the compressed air from an air compressor, from a predetermined reference pressure, multiplying the pressure deviation by a predetermined constant, and adding the pressure deviation multiplied by the predetermined constant to the calculated air/fuel ratio. In this way, the corrected air/fuel ratio can be maintained substantially constant even if a load increases in steps.
