Design Of Platform For New Digital Generator And Transformer Relaying Protection Device

With the demands of more higher performance to Generator and Transformer Relaying Protection Device are increasing by field, the development of software and hardware are need by themselves, the hardware platform composed by sixteen bit high precision A/D added thirty-two bit embedded micro-controller is asked to design and develop on the basis of summarizing and inheriting successful experiments of microcomputer protection device. The system fully utilizes the embed microcontroller merits such as strong arithmetic ability,flexible logic function,abundant periphery resource, and so on. And the system uses a large volume of periphery memory chip, so the functions such as sampling with high speed in real time,parallel computing in real time,program facing on object module,fault report tracking all the time,employing complicated advanced protection theory are ensured in the Generator and Transformer Protection Device. In software, the traditional software design idea is adopted, and the newest software design method which is on the basis of multi-tasks real time operation system is put to use. By analyzing and comparing and running practice, the platform owns notable advantage such higher reliable,easier development maintain and upgrading and enlarging.
