HJD6000- background monitoring software system

 HJD6000- background monitoring software system Emil background monitoring software systems when applied to summarize the scope of protection and low-voltage substations years of research, development and practical experience integrated automation system, will protect, measure, monitor and control the formation of tightly integrated 6KV-110KV substation in the new low-voltage power grid integrated automation systems. Features ▲ distributed system protection and control functions and design by object, set the protection, monitoring and control functions, protection, and control both independent, and mutual integration, protection, monitoring and control with the aid of computer network switching substation level computer monitoring system data, reduce the number of secondary wiring, increased functionality, saving investment, improve system reliability. ▲ use of advanced network architecture provides dual Ethernet station level structure, the choice of fiber optic networks; spacer layer CAN fieldbus for all equipment used to achieve a spacer layer and substation level contact by HJD-3310 communication manager, with good reliability and flexibility. ▲ support hardware for the network to provide network hardware on the way to GPS time. When the GPS unit is given only a pair of contacts, via a network, to provide the hardware for all devices, avoid the past to provide a pair of contacts and a pair of wires for each device trouble. ▲ open design, resource sharing, easy to use and maintenance of open system design, configuration, monitoring the completion of the full protection of information and protection in record analysis, Windows NT-based design, reliable and safe. The system is divided into three overall: substation layer, communication layer, the spacer layer. The spacer layer is mainly composed of the protection unit, and control unit. HJD100 series protection, monitoring and control devices to solve the problem devices in harsh environments (high temperature, strong electromagnetic interference, humidity) long-term reliable operation, and the overall design, through the protection, monitoring and control devices combine the exchange of information, reduce duplication of equipment, simplify the design, reducing the cable. Network communication layer supports single or dual network structure, support full Ethernet, but also provides other networks; adopt balanced dual network traffic management, effectively ensure the timeliness and reliability of network transmission; power industry standard communication protocol using the statute, can be easily to realize the interconnection of equipment from different manufacturers; optional fiber optic network, and enhance communication immunity to electromagnetic interference; provide remote communication capabilities, can be different in different statute forwarding information packets to different scheduling or centralized control station; in communication layer, using the gateway instead of some automated systems commonly used in communications controller, its biggest advantage is that, first, safety. Gateway server plays a similar role to connect each node in the network, security measures can be integrated with the communication feature set, which can effectively isolate the impact of network externalities; Second, network openness: it easy to connect different manufacturers equipment, to avoid specially developed for a given time, or a handful of suppliers controlled; Third, the network can be expanded. Allows people to change and modify the part of the system without the need for a large cost. Substation layer using a distributed system architecture, offers a variety of forms of organization, which can be a stand-alone system, also redundant multi-machine system. Flexibility, high reliability and easy system expansion. Transformer substation level for duty, dispatching personnel to provide substation monitoring, control and management functions, user-friendly, easy to use. Component technology used for software features "plug and play", can satisfy the need for a comprehensive automation system. HJD6000 type hierarchical distributed substation automation system uses advanced technology and careful design, the substation protection and control both relatively independent and mutual integration, protection and control and external communication free from influence to ensure the protection of the safety and reliability sex, while information sharing, provide a complete solution for substation automation. HJD6000 aid of advanced computer network communication technology, information exchange within and outside the substation subsystems, devices, substation automation system not only supports a variety of voltage substation required protection, monitoring and control functions, it also provides the necessary substation automation a variety of advanced applications, such as substation fault information required, recorded wave information analysis and processing functions for substation security, stability, economic operation provides a solid foundation.
