Devices in The Process Layer Series for Smart Substations That Can Be Independently Controlled

Application Scenarios

Applicable to smart substation process layers that are independently controllable across all voltage levels. Implements process layer acquisition, transmission, and control functions for smart substation lines, transformers, busbars, sections, and other intervals.

System Composition

Includes merging units, intelligent terminals, body intelligent terminals, integrated merging and intelligent units, acquisition and execution units, etc.

Functional Features

Independently Controllable

Adopts domestic chips and operating systems, reduces reliance on external supply chains, and enhances data security and system stability.
Reliability Optimization Design

Dual-mainboard redundant design for acquisition and execution units, both mainboards independently handle analog loop acquisition, 5V transmission, GOOSE transceiver functions without interference, and can operate independently.
High-Precision Sampling

The phase difference between the cascaded voltage data output received by the device and the metering voltage/measured current data output collected by itself can achieve high precision.
Fast Trip Response

The response time from receiving the protection trip command to hard contact action is ≤4 ms.

Typical Cases

Xiaojian 110 kV new-generation high-reliability substation in Yancheng, Jiangsu
Fuji South 110 kV new-generation high-reliability substation in Qi County, Kaifeng, Henan
