Functional value:

Collect the power parameters of each circuit (such as voltage, current, and power factor) to provide data for energy 

consumption analysis;

Support communication protocols such as IEC 61850, interface with the EMS system, and achieve energy dispatching 

and optimal control.

Iii. Petroleum and Natural Gas Industry

Control of oil and gas pipelines and pumping stations

Application scenarios: Protection and control of pump units and compressors in oil pipelines and natural gas 

compression stations.

Functional value:

Monitor parameters such as pipeline pressure and flow rate, and link them with the protection logic to prevent 

overpressure or leakage accidents;

Unattended monitoring of pumping stations is achieved through remote communication to enhance operational 

efficiency.

2. Power system of offshore oil platforms

Application scenarios: Power distribution, generator protection and load management on offshore platforms.

Functional value:

Differential protection and reverse power protection are carried out for the platform generator to ensure the reliability 

of power supply.

The high-protection grade design adapted to the Marine environment ensures the stable operation of the equipment 

under harsh working conditions.

Iv. Infrastructure and Public Utilities

Power supply for railways and urban rail transit

Application scenarios: Protection and control of railway traction substations and catenary systems.

Functional value:

Carry out overcurrent protection for the traction transformer, quickly cut off short-circuit faults, and ensure the safety 

of train power supply.

Support high-reliability communication protocols (such as PRP/HSR) to meet the real-time requirements of rail transit.

2. Municipal power grid and Smart grid

Application scenarios: Automation transformation of urban distribution networks, terminal devices in smart grids.

Functional value:

As an intelligent power distribution terminal (DTU), it realizes fault location, isolation and non-fault area recovery (FA);

Communicate with the distribution automation master station and support the collaborative control of the self-healing 

power grid.

V. Key Features Support Application Scenarios

Communication compatibility: Supports protocols such as IEC 61850 and IEEE 802.1d, facilitating system integration 

with different manufacturers and suitable for large-scale cross-platform projects.

Programmable logic: Users can customize protection logic and control strategies, flexibly adapting to the special 

process requirements of industries such as chemical engineering and metallurgy.

High-reliability design: Equipped with self-diagnosis and anti-interference capabilities, it is suitable for harsh industrial 

environments (such as high temperature, humidity, and electromagnetic interference scenarios).

Summary

The core of the application lies in the integrated capability of "protection + control + monitoring + communication". 

It can not only serve as a key protection device for the power system but also be integrated into industrial automation

 processes to achieve intelligent equipment management. It is particularly suitable for scenarios with high 

requirements for reliability and real-time performance. If a further understanding of the application details of a specific

 industry is needed, the scene background can be supplemented to provide a more in-depth analysis.
