To improve traditional voltage-time mode feeder automation system, and considering the problems of GPRS and as security vulnerability and communication interrupt and delay, an improved voltage-current mode feeder automation system based on GPRS is presented. GPRS is only for sending command of close blocking, not for telecontrolling switch to open or close. Load break switches are equipped with simplified...
With the gradual popularization of DAS (distribution automation system), the amount of automated switches continues increasing as well as the amount of analog and digital values, the traditional relational-based real-time database is relatively difficult for distributed acquisition and processing of switch data. This paper presents a scheme of object-oriented real-time database compatible with IEC61970-CIM...
