ROTEC specialists successfully connected two Alstom GT13E2 gas turbines operated at Novogorkovskaya CHPP of PJSC T Plus to the PRANA prognostics system. The total capacity of the equipment is 360 MW. The PRANA mathematical model monitors and every second updates 344 operating parameters of the connected Alstom turbines.
Thus, today the PRANA system supports the equipment of all three major gas turbine manufacturers - General Electric, Siemens and Alstom. All the main equipment of power generating units, including steam turbines of UTW, GE and Siemens, generators manufactured by ABB, General Electric, Electrosila and Alstom, heat recovery steam generators (Taganrog Boiler-making Works Krasny Kotelshchik, ZiO-Podolsk, Belenergomash-BZEM LLC, Istroenergo Group, BBS, EMAlliance and HRSG), as well as the booster compressor stations BORZIG, Howden and GEA Grasso GmbH, is connected to the system. PRANA operates with all automated process control systems common in Russian power generation - GE, Siemens, Alstom, Tekon and Kvint.
Today PRANA ensures safe and reliable operation of more than 80 power generating equipment units. Its overall capacity exceeds 3.2 GW and the cost is 3 billion US dollars. In 2018 the project team introduced a number of new functions into the system - technologies for creating distributed expert teams, mobile applications for remote access of experts, plant personnel and power generating company management, neural networks for defect localization, modules for vibration diagnostics and automated calculation of plant components residual life.
The PRANA prognostics system detects defects in equipment operation 2-3 months before they can lead to an accident. It automatically creates an operating equipment reference model, with which it subsequently compares the equipment's sensor readings. PRANA finds the differences between the digital image and the actual state of the installation, and also determines the reasons that have led to them. This method facilitates the detection of defects in advance, and the objective assessment, and thus monitoring, of the equipment's technical condition.
