The Integrated Automation System of Substation.pdf

(1) System Structure

The automation system of 35 kV - 500 kV power transformer substations integrates protection, control, monitoring and measurement functions and is divided into three layers: an isolation layer, communication layer and devices of transformer substation layer.

As for the communication layer, it is easy to connect devices from different vendors by following standard specifications. Dual-plane industrial Ethernet network guarantees reliability.

(2) Requirements of Network

1.Based on the dual-plane network architecture, the automation system of the power substation connects all devices via two isolated networks, thereby obtaining high reliability. In addition, the two networks can be used separately for communication and fault wave-recording.
2.The communication devices must be compliant with IEC61850-3 specifications, and be qualified for high temperatures, strong EMI and humidity.

(3) Implementation

The industrial Ethernet switches such as SICOM3024, KIEN3024, KIEN3016, KIEN2000 and KIEN1000 are widely employed in the automation systems of 110KV, 220KV, and 500KV transformer substations.
