Analysis of typical problems of primary frequency modulation

After the promotion of primary frequency modulation remote test, the network source platform will conduct test regularly every month and analyze the unqualified test. This paper focuses on the phenomenon of unqualified primary frequency modulation test, infers the causes of unqualified primary frequency modulation test, and divides five kinds of problems according to the causes: poor control and regulation quality, slow DEH response, insufficient unit regulation margin, influence of operation mode and poor flow characteristics of regulating valve. This paper gives the corresponding qualitative solutions to the five types of problems.
