Design of Integrated Automation System of Energy-Fed Supply Substation

In this paper, an integrated automation system of energy-fed supply substation based on computer technology and network communication technology is presented. Unlike the traditional secondary system of substation, this system adopts the embedded system to achieve the data acquisition, uses industrial Ethernet as transmission medium, utilizes the intelligent software to monitor automatically, measurement, control and micro-computerized protection for main equipment of substation. The practical operation demonstrates that the integrated automation system increases the degree of automation, increases the economic benefit, improves quality of power energy, and reduces operation costs.
