Over a long period of time, the UFLS scheme in Hebei electric network is mainly established by the meeting and manual calculation. With the continuous expansion of network scale and the increasing requirement of customers for power supply quality, it is necessary to develop a set of software for calculating UFLS scheme to provide the precise calculation tool, improve the work level of establishing UFLS scheme and dispose a reliable third line of defence for the network. This paper discusses the dynamic frequency characteristics of modern power systems and the methods of setting UFLS scheme, at the same time we develops a software for calculating UFLS scheme of Hebei grid. Based on BPA, this software mainly functions are setting and checking of a UFLS scheme, modifying the basic data and arranging the checked results, etc. This software has friendly interface and extensive applicability, and it's flexible and convenient with the powerful calculation functions.
