The JOYO-F/K dispatching and centralized control automation system is used for centralized monitoring of substations in large and medium-sized petrochemical, refining, and other industrial enterprises. It focuses on electrical automation monitoring and control, achieving applications such as electrical data acquisition, remote control, anti-misoperation locking, operation ticket management, and video surveillance. This ensures reliable power supply for precision equipment and a large number of medium- and low-voltage motors, ensuring stable operation of power supply lines, transformers, switches, and secondary equipment, and enhancing the intelligence and informatization of the power supply system for industrial enterprises. 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.
The JOYO plant-station integrated automation system can achieve power monitoring for substations at 500kV and below, and independently complete protection and control for substations at 110kV and below. The system integrates functions such as monitoring, control, measurement, waveform recording, relay protection, safety automation devices, communication, and remote control into a unified system. It realizes vertical coverage of scheduling, centralized control, and substation automation systems, and integrates power monitoring, safety management and control, and auxiliary control into one comprehensive monitoring solution, providing an intelligent, economical, and comprehensive automation solution for the power system.
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.
Traditional disconnector operations face challenges such as complex procedures, low operational efficiency, and high risks of misoperation, making them unable to meet the demands of lean substation management and the digitalization of power grids. The JOYO-A1 one-click sequence control system for substations is built on integrated substation monitoring and intelligent anti-misoperation technologies, combining magnetic sensing, micro-motor control, and secondary anti-misoperation technologies. It creates a new generation of one-click sequence control system with "comprehensive state awareness, full remote control of equipment, comprehensive anti-misoperation verification, and full coverage of operations," providing intelligent, efficient, and safe substation operation solutions for customers in the power grid, power plants, and petrochemical industries.
The UT-Z300B intelligent substation integrated automation system is a next-generation solution that integrates monitoring, control, protection, measurement, anti-misoperation, and telemetry functions. It is developed based on cloud computing, IoT, mobile intelligence, intelligent sensing technologies, and big data, with unified standards, a unified platform, optimized configuration, and enhanced security, all while adhering to an open design philosophy. The system follows a top-down design philosophy, adopting a layered, distributed structure while adhering to grid technology specifications. It optimizes secondary circuits, reduces the workload of commissioning and maintenance, and makes substation operations more economical, reliable, and intelligent. The system can be applied to both intelligent substations and conventional substations.
