Smart terminal
The site contains multiple complex production systems and processes that use different communication protocols and data formats, making it urgent to address compatibility issues between system platforms.
As technology continues to advance, new equipment and systems are continuously emerging. The production environment in petrochemical enterprises involves heavy loads and a large number of devices, making technology updates and maintenance challenging.
The petrochemical industry has extremely high requirements for the safety and reliability of production processes. However, the system may face risks such as equipment failures or human errors, leading to system paralysis or production accidents.
In the event of an emergency or system failure, the emergency plans and warning information may be insufficient, leading to an inability to respond effectively and promptly in critical situations, thereby increasing production risks.
The petrochemical electrical automation control system is applied in large and medium-sized oil refining enterprises for centralized substation monitoring. It focuses on electrical automation monitoring and control, enabling data collection, remote control, anti-misoperation interlocking, operation ticket management, and video surveillance applications. It ensures the reliable power supply of high-precision equipment and numerous medium- and low-voltage motors, while maintaining the stability of power supply lines, transformers, switches, disconnector operations, and secondary equipment, enhancing the intelligence and informatization of petrochemical power supply systems. The system adopts advanced cross-platform technology and a distributed architecture, meeting the high reliability and safety requirements of power systems. The unified development platform and integrated diagram model technology support the latest one-click sequence control and secondary equipment monitoring technologies, ensuring reliable operation of electrical equipment and fast operations, reducing the workload for electrical maintenance personnel.

Cross-platform compatibility
The system implements the concept of "one code, run anywhere," supporting UNIX/Linux/WINDOWS operating systems and IBM/SUN/HP/ALPHA/X86 hardware platforms. It also supports fully domestically produced hardware, operating systems, and databases, ensuring information security and addressing supply chain bottlenecks.
Distributed architecture
The system uses layered design technology, with the entire system composed of computer hardware/operating system/general platform/specialized platform/application platform/power application software systems. It provides middleware for transparent database access based on the IEC61970 standard; the application platform offers features such as graphical management, interface management, data acquisition, SCADA applications, web applications, reporting, and printing.
Integrated monitoring, anti-misoperation, and video functions
The system integrates power automation monitoring, electrical anti-misoperation, and video monitoring into one, reducing the need for additional computer resources. It brings together various operational scenarios, providing integrated simulation, operation, and alarm video display, suitable for unattended substations and improving centralized monitoring efficiency.
Classified and graded alarm information display
The system simultaneously receives data from multiple substations and classifies and grades alarm information for display, improving the readability of alarm information. Accident, sequence of events (SOE), and pre-alarm information are displayed on separate pages, with different alarm levels shown in different colors and sound alerts. Non-critical alarm information can be hidden from display but still recorded and retrievable.
