Abstract: In this paper, the necessity of the fast cut back(FCB) function in thermal generation units is discussed according to the requirements of the power system operation, meanwhile, the key technologies and fundamentals to realize the FCB function are also put forward. Taking a 1 000-MW unit with no FCB function designed in the construction period for example, the system modification and control logical design schemes as well as the testing procedures of the FCB function are proposed based on the analysis of the unit configuration. Then, the FCB test results under 100% load condition are obtained, which proves that the modification and implementation schemes are correct and effective with the advantages of short modification cycle and low cost and can bring security and economic benefits to the power grid and the unit itself.

Key words: 1 000-MW thermal power unit, fast cut back (FCB), technical renovation, key technology, control logic design
