Paper Title:
Digital Control of the Substations Based on IEC61850
  Abstract

The promulgation and promotion of IEC61850 provide a basic platform for the development of the digital substation. In this paper, the present situations and problems of the digital substation 220KV Baicheng are introduced and analyzed, And some schemes are proposed including the configuration of DF1900 monitoring system in substation layer and DF1925 controlling system in interval layer, and the optimization of communication networks and the access of the electronic transformer.The evaluations of successful transformation are summarized from the reliability and availability and flexibility in the end. From evaluations of the scheme, this transformation makes the reliability and availability of the digital substation 220KV baicheng improve greatly, but also enhances the flexibility of system. Moreover, the transformation also saves much money to purchase equipment of substation, so it also provides a new method to change for a large number of old substations to digital ones.
