Transmission
Energy Management System
Dispatch automation is the core technical means of power system operation and management, which integrates advanced computer technology, communication technology, and control technology to achieve real-time monitoring, analysis, and optimization control of the power system operation status. Based on over 30 years of experience in the power system, SIFANG can provide core products such as EMS master stations and substation RTUs for power companies. At the same time, it integrates the overall dispatch automation solution of the power communication system to meet the requirements of integrated control, clean energy management, power grid analysis, etc., and improve the safety, economy, quality, and environmental protection operation level of the power grid.

Digital Substation
In digital substations, which enable real-time data exchange of voltage, current, and status information among IEDs via SV and GOOSE protocols, there is a growing trend of substations into process and station levels. Interface IEDs, such as SCUs and MUs, traditionally responsible for managing binary and analog data with primary equipment, are now installed directly in the yard. This shift offers multiple benefits, including reduced cabling, lower civil infrastructure costs, simplified installation, and improved safety, especially when using fiber optic technology. SIFANG digital substation solution provides flexible data acquisition methods—via hardwire, GOOSE, or SV—and supports diverse time synchronization techniques, including SNTP, IRIG-B, and IEEE1588. The solution also includes a comprehensive range of protection relays, BCUs, network analyzer and NDMEs.

Protection Management System
SIFANG Protection Management System (PMS) collects and integrates the operation information and fault-related information of protection equipment in real time and conducts centralized analysis to achieve functions such as online monitoring of protection equipment, precise fault analysis, classified statistics of alarm information, intelligent inspection, ledger management, comprehensive report integration, etc. When the power grid operates normally, the system monitors and manages secondary equipment online; when there is a power grid fault, it provides information support and decision-making reference for handling power grid accidents.

Simulation and Training/Digital Twin
The substation simulation training system comprehensively simulates the entire operational workflow of substation by integrating equipment algorithms with power grid dynamic calculation programs. It enables full-scope training and assessment on power grid/substation primary & secondary equipment cognition, operation maintenance, and fault handling. Utilizing advanced 3D visualization rendering technology, the system provides users with immersive hands-on operational experiences. It also supports substation design optimization and rational decision-making through simulation-based analysis.
