Substation automation is an indispensable and vital component of the electric power industry, primarily consisting of automation equipment, computer hardware and software, and communication systems. It ensures the stable operation of power system equipment and systems. Power system automation is further divided into power grid automation and power generation automation. Power grid automation, in turn, includes substation automation, distribution automation, and dispatch automation.
Therefore, in today's society, information management technology can drive rapid economic development, and the intelligent transformation of substations is an inevitable trend in the continuous development of power systems. In the future, China's smart substations will follow trends toward integration, miniaturization, and coordinated development.
1. Integration
Traditional electromechanical protectors only incorporate corresponding integrated circuit systems. In the future, computer technology will be integrated into these integrated circuits. During the measurement and control process, the computer system will organize and record various operational data, then transmit the processed data to the corresponding storage units. When a fault occurs in a part of the power grid, the computer can serve as a medium for information exchange, promptly feeding back the fault status to the control terminal, which greatly reduces fault repair time.
2. Miniaturization
Miniaturized devices are primarily used to enable on-site environmental protection while enhancing the speed, reliability, and interference resistance of self-protection mechanisms. This achieves a "plug-and-play" maintenance management model, leading to periodic cost savings for enterprises.
3. Collaboration Between Main and Substations
Based on a more comprehensive and open platform and service-oriented communication network protocols, the system enhances the level of information exchange and interaction between main and substations. This enables system functions such as on-demand services, subscription-based push services, and request-response services, significantly improving operational and maintenance management as well as innovation and development.
In summary, the future development trends for substation automation in the smart substation industry are very promising.
