The Overall Scheme to Realize the Automation of 110kv Transformer Substation and Below

The key of the construction of electrical network in the new period is to reach the comprehensive automation of the transformer substation, develop fully the computers when there is unmanned, and improve the quality off the power supply and the level of management. The paper analyses principles, design and technological features of dispersing computer protection and control unit about DCAP-3000 series, suggests the new overall scheme of the automatic system with 110kv substation as example. Moreover, the paper see the prospects of the automation technology of the transformer substation.
