Siemens implements primary frequency control technology for NTPC Dadri

Siemens Limited has commissioned India’s first condensate throttling-based primary frequency control solution at NTPC Limited’s National Capital Power Station (NCPS) at Dadri (Stage II, Unit 6). Condensate throttling, based on Siemens’ SPPA-P3000 Frequency Control Solution, will be used for immediate generation of additional power for frequency control. The principle of condensate throttling is that the turbine control system opens the governor valves to utilise the reserve steam storage capacity of the boiler. When additional power is needed, the condensate flow is reduced, usually by throttling the condensate control valve. In the current regime of renewable energy integration into the power grid, this technology provides flexibility to the thermal power plant unit.
