Multiple systems or function modules exist within the substation/station house, each operating independently, forming "monitoring islands" that cannot be managed uniformly or effectively.
Many devices in the substation/station house are not networked for information processing and only allow local monitoring and control, with maintenance relying on traditional manual inspection, resulting in insufficient informatization and low inspection efficiency.
Currently, all doors in the substation/station house use mechanical locks, posing significant safety risks. External personnel can copy keys and open doors arbitrarily, leading to the risk of accidents from unauthorized operations on internal equipment.
The coexistence of scattered multi-systems or functions in the current substation/station house not only increases investment costs but also greatly increases maintenance costs, reducing the timeliness of problem handling and resolution.
The system is an automation system for monitoring and controlling equipment in the substation/distribution station house. By using advanced sensors and monitoring equipment, it can monitor the operational status of electrical equipment, environmental information, and fire and safety information in the substation/distribution station house in real time to ensure the safe operation and effective management of equipment. It also provides real-time alarm functions for abnormal conditions and remote control functions, making it convenient for maintenance personnel to remotely operate and maintain distribution station equipment, significantly improving the reliability and management efficiency of substation/distribution station operations.

The new energy automation monitoring system is mainly used for solar photovoltaic power plants, addressing the challenges of widely distributed data acquisition devices and difficulties in unified supervision. The system utilizes the latest information technologies such as big data, cloud computing, and artificial intelligence to collect, store, and analyze photovoltaic power plant data. Coupled with powerful edge computing capabilities and robust national security certification, the system improves operational efficiency, stability, and security, reduces maintenance costs, optimizes resource allocation, and promotes the sustainable development of the new energy industry.
Secondary equipment is responsible for monitoring, controlling, regulating, and protecting primary equipment, forming a critical part of protection and control circuits. The correctness of secondary equipment status directly affects the stability and reliable operation of the primary system. As the one-key sequence control mode is promoted in the power grid, secondary equipment such as locking plates, circuit breakers, and switching handles, which cannot be operated remotely, still require on-site manual operation by O&M personnel. This significantly limits the rapid development of the one-key sequence control mode. The intelligent secondary monitoring system enables comprehensive monitoring of secondary equipment status, remote control, status inspection, secondary anti-error, and online analysis. It effectively resolves issues such as low efficiency in manual inspections, high risks of human error, and low levels of intelligence in secondary equipment, providing strong technical support for the construction of new intelligent power grids.
