Digital twin solutions

Substations are a very important component of the power system, which used to convert electricity from high-voltage transmission lines into low-voltage distribution networks. With the acceleration of industrialization and urbanization, the demand for electricity is also increasing. Digital twin is a digital modeling method based on virtual reality technology, which can simulate the real world in a digital environment. In the substation scenario, digital twins can provide highly accurate simulation, helping engineers better understand the actual operation of the substation and providing better support for managing and maintaining the substation.

3D design model: Complete the storage processing of the substation (converter station) 3D model, and carry out normative inspections, model reduction, model storage management, ledger association, and primary wiring diagram association according to the 3D model specifications.

Data interface development: Sort out the existing relevant data of the substation operation and maintenance automation system, and develop data service interfaces. The development of data interfaces for substation engineering includes the distribution and viewing of meteorological information, oil spectrum monitoring data, iron core grounding monitoring data, and image videos within the substation. The development of transmission engineering data interfaces includes ice monitoring data, satellite mountain fire warning data, tower meteorological monitoring data, typhoon monitoring data, earthquake monitoring data, image video and alarm data, distributed fault distance measurement monitoring and alarm data, tower tilt monitoring and alarm data.

Data access: Building a smart substation requires real-time collection and processing of operational data from the substation, establishing a reliable data collection and processing system, including sensors, data collectors, data transmission and storage, etc.

Sensors: Sensors are important equipment for data collection, which can sense and collect various operational data of substations, such as voltage, current, power, temperature, humidity, pressure, vibration, etc. Sensors can transmit data to data collectors or data transmission devices through wired or wireless means.

Data processing and analysis: Data processing and analysis are important links in achieving the operation and management of smart substations. By processing and analyzing the collected data, it is possible to monitor and diagnose the operational status of substations, and achieve functions such as fault prediction, energy consumption management, and optimized scheduling of substations.
