Embedded Protection Information Processing Slave System Of Research

Protection information processing system is for the purpose of realizing the equipment management, the running status surveillance and the movement fix-value calibration to the second equipments of the power system, as well as the integrative and effective utilization analysis to the information of the electrical network’s unconventionality or fault that are recorded by the second equipments, and so on.The national electrical network company already sets the explicit request of the establishment,the implementation and the inspection to the above system in a series of documents.Based on many years of protection information processing slave system of operating experience, this papers aims to design and implement a new protection information processing slave system in order to meet the needs of digital substation. The system consists of two parts:hardware system and software system.The protection information processing slave system for the overall design is firstly planned in this paper.A embedded protection information processing slave system is designed for the parking lot management system to meet the most requirements.Secondly the development platform with EP9312microprocessor as its core is discussed, foregrounding its hardware design and realization.And then based on the hardware platform, the transplanting of the embedded Linux operating system is elaborated;software architecture of the embedded Linux operating system is described. Finally, this paper combine field application of the embedded slave system,designs test model of the embedded slave system,gives the datas of performance testing and field application summary.The embedded slave system given in this paper is different from early slave system which formed with IPC. The embedded slave system applied the technology of embedded system and Ethemet,has innovation both general program and design theory.
