Design Conception of Integrated Automation System for 110kV Substatio

This paper set about from integrated substation to considerate the functions such as relay protection, supervision, monitoring and control telecommunications, direct current and five protections. The integrated design conception of relay protection, monitoring and control and telecommunications is intended to recommend in this paper, which can prevent the device from being collocated repeatedly, reduce cost, and also be beneficial to running management and maintenance of substation.
