The substation gateway can not only realize information transmission, synthesis, editing, management and equipment monitoring functions between various automation devices, smart meters, substation intelligent auxiliary equipment and main computers, but also can be used as master control substation front-end machine of integrated automation system.
The use of scientific and technological means to reduce production costs and improve labor efficiency is development trend of factory manufacturing industry. The substation gateway is advantaged in rich protocols, customized development, stable and reliable running, which suitable for large-scale, high-demand integrated automation systems and dispatch automation and distribution automation system. Following is more function of the gateway.
Run multiple independent protocols, each protocol can operate as a master or slave or both.
A protocol’ information including protocol name, device type, telemetry, remote signaling, remote pulse, remote control, fixed value, SOE, SOE value and other measurement points and related attributes are pre-defined through a separate protocol manager
Audible alarm: receive the alarm information of smart device, drive audible alarm, and save the history of alarm information.
Message monitoring and recording: detailed message monitoring and recording (each protocol saves the history of message as needed, and can be retrieved according to time), which is convenient for testing and analysis.
Powerful communication processing capability can monitor hundreds of nodes at the same time.
Fully enclosed anti-jamming unit chassis, new back-inserted structure design, double-layer shielding, and bus not cited to reduce the impact of electromagnetic interference.
Each protocol can open multiple data channels, including a serial channel and one or more Ethernet channels, or customized channels such as CAN network, COM components.
The switch remote signal adopts dual position acquisition, which avoids the problem of remote operation jitter of switch operation.
Each protocol is a DLL plugin that is dynamically attached to the specification library for selective use when communicator is started.
Predefined information can be exported as configuration file or imported from a configuration file.
Each protocol plug-in DLL provides the name of the protocol, and the main program will look for predefined information for the same-name protocol from protocol-predefined library.
