12 DISC
Develop a starter that enables the powering up of the Russian Gas Turbine Generator GTG 1250-2E fitted on board IN ships.
IN ships have Russian origin gas turbine-based power generators of 1250 KW. The Gas turbine-based turbo compressor is the prime mover of the power plant that is coupled to a Reduction Gear box. The other end of the Reduction Gear box is connected to the alternator. The whole power plant is called Gas Turbine Generator (GTG-1250-2E). However, to start and power up the GTG, the initial torque is provided by two DC starter motors and are mounted on the Reduction Gear Box. The engagement cycle of the starter and the powering of the turbo compressor follows a pre- determined start cycle. The starters provide two types of start i.e cold and hot start in which the starters draw current in the range of 1900-3000 Amps. The GTG starters are of Russian origin and there is no indigenous substitute for the same. The challenge is to develop a starter (Qty01) that meets the form, fit and function in providing the initial torque requirements of powering the GTG as per the start cycle. Based on the trials on overhauled GTG at Eksila, Visakhapatnam, the item will be replacement for Russian GTG 1250 2E.
