In November 2014, startup operations began, and on November 11 turbine and generator were plugged in the network. At this stage, mastering of power is performed, after which the turbine unit will be put into commercial operation.
It is the second power unit of Zaporozhskaya TPP modernized by "Turboatom" previously, in 2012 the turbine was launched at the unit No.1.
K-300-240-2 steam turbine was modernized at Zaporozhskaya TPP with replacement of HPC, IPC and the first flow of LPC, blades and the last fifth stage diaphragms of the second and third low-pressure flow of units of HPC and IPC valves. The plant has also implemented electrohydraulic control system on basis of software and hardware complex of control system of the turbine and introduction of hydrostatic lift system of rotors. As a result, K-300-240-2 turbine exhausted its resource was replaced by K-325-23,5 unit.
After modernizing the increase in power of the turbine is not less than 10 MW, the efficiency of HPC in a mode of maximum steam passage will increase by 3,3% and reach 89,3%, the efficiency of IPC will increase by 2,5% and will be 93,6%, the efficiency of LPC - up to 84,4%. The reduction of specific heat consumption is not less than 32,5 kcal/kWh. The service life of power equipment will increase by at least 15 years.
