Application of “firmsys” of CGN in emergency diesel engine of nuclear power plant
On March 26, with the successful no-load start-up of the newly added emergency diesel engine in Ling'ao Nuclear Power Plant Phase-II, it marked that China's home-grown nuclear grade digital I&C platform “FirmSys” was applied in the field of emergency diesel engine I&C system of nuclear power plant for the first time, speeding up the localization and digitization process of emergency diesel engine I&C system. Compared with the relay scheme used in the past, the digitalization of the nuclear power plant emergency diesel engine I&C system based on “FirmSys” not only improves the reliability of the system, but also greatly improves the flexibility of the system, and makes the maintenance more convenient.
First successful start-up of emergency diesel engine in Ling'ao Nuclear Power Station Phase-II
Emergency diesel engine, namely emergency diesel generator set, is an independent power supply system specially set up to ensure the safety of nuclear power station in case of emergency, which is responsible for providing power for emergency backup auxiliary system of nuclear power station.
In addition to the newly added emergency diesel engine project of Ling'ao Nuclear Power Station Phase-II, the “FirmSys will also be applied to Ling'ao Nuclear Power Station Phase-I, Daya Bay Nuclear Power Station in-service emergency diesel engine modification project, and Taipingling Nuclear Power Station Phase-I emergency diesel engine I&C system project.
In addition, the “FirmSys” will go global and be applied to the emergency diesel engine system of Hinkley Point C Nuclear Power Plant in UK, which is expected to achieve a breakthrough in the application of “FirmSys” in European nuclear power plants. This project is in the engineering design stage.
