Abstract

A starting apparatus for a gas turbine-generator mounted on an electric motor driven motorcar includes a gas turbine and an A.C. generator with A.C. output terminals coupled directly to the turbine. A rectifier with D.C. output terminals is connected to the A.C. output terminals of the A.C. generator. A battery device is connected to the D.C. output terminals of the rectifier. An inverter has D.C. input terminals connected to the floating battery device in parallel and A.C. output terminals from which an A.C. output is derived. A control circuit is connected to the inverter for controlling the speed of the motorcar. At least one A.C. motor energized by the A.C. output of the inverter for driving the motorcar is provided. A switching device connects the A.C. output terminals of the inverter to the A.C. output terminals of the A.C. generator when the gas turbine is started and connects the A.C. output terminals to the A.C. input terminals of the A.C. motor after the gas turbine is started. A fire detecting device is connected to the switching device for detecting the self ignition of the gas turbine.
