  • RCS-9698G/H Gateway

  • The RCS-9698G/H gateway is used to establish a communication links between a substation and the Load Dispatching Centers, or Grid Control Centers, in order to achieve data exchange. It is capable of communicating with several dispatching centers simultaneously via different telecommunication channels according to the applied protocol. Industrial hardware with embedded components is adopted instead of PC technology with weak rotary machinery (Hard disk, Cooling Fan, etc.). RCS-9698G/H supports both conventional communication channels and modern powerful Ethernet, and is fully complient with the IEC-61850 international standard communication protocol. RCS-9698G can be used independently, while RCS-9698H adopts duplicated scheme with two RCS-9698G units to realize HOT-STANDBY or Dual- HOT running mode.

  • Collect Information from IEDs
    Depending on the applied protocol and database configuration, and also owing to its powerful communication interface, RCS- 9798G/H can communicate with various IEDs in a substation, and automatically collect any wanted information from them, e.g. sequence of events (SOE), binary signals, transformer tap position, pulse counting of electricity quantity, communication states and so on. In addition, all the collected information can be sent to dispatching center.
  • Small-capacity memory storage
    With small- capacity of industrial-grade NANDFLASH memory (128MBytes for single machine while 256MBytes for dual machine system), information of events(protection relays’ self-checking information, trip event records, fault information, settings modification records and so on), remote command from dispatching center including selecting and executing of the binary output and setting modifications, remote regulation of transformer tap position, remotely signal reset event and so on are stored, which are automatically collected from various BCU, protection relays and some other auxiliary IEDs.
  • Settings management
    RCS-9698G/H can upload/download and modify settings (only the currently activated group of setting can be managed) of various expected protection relays and auxiliary IEDs. Setting management can be done by Debugging Tool or achieved by dispatching center up to the applied protocol.
  • Communicate with dispatching center via various protocol and interfaces
    Appreciated to its powerful communication function, RCS-9698G/H can send all collected information to dispatching center via multiple standard communication interface (e.g. electrical/optical Ethernet port, electrical/optical serial port and so on.) and any desired RTU protocols (any new protocols are provided on client’s request). Moreover, information sent to dispatching center can be selected according to the necessity.
  • Information marshalling and synthesizing
    An important aspect of multiple protocol applications of RCS-9698G/H (e.g. communicate with several dispatching centers) is the proper marshalling of the data to be transferred according to the appropriated RTU protocols. With the help of Configuration Tool, signal synthesization is implemented, such as General Alarm, General Failure.
  • Signal transmitting
    Depending on the utilized RTU protocol, all the collected signals can be selectively sent to dispatching center. Signal selection can be done during RCS-9698G/H database configuration by Configuration Tool.
  • Multiple switchover Scheme for Dual- machine configuration
    Whenever an error happens in the HOST MACHINE (e.g. CPU or power supply failure), the HOT STANDBY MACHINE will be forced to be as a host one. With a dedicated seamless switchover technique, the equipment will guarantee that records are not lost during a switchover. There are up to four kinds of dual- machine switching scheme.
  • Time Management
    As the equipment Real Time Clock has small drift per day, therefore, in order to have a correct time for time tagging of event etc., the operator should set its time periodically or it should be synchronized by a master clock. With a correct clock, the equipment can be configured to synchronize its managed IED’s clock.
  • Diagnostic
    The equipment can continuously self-supervise on its firmware. Once a hardware/software fault happens; its watchdog will make the CPU card restart.
  • Applicable to new substations or modernization of existing substations
  • Fit for installation in cubicles
  • Supporting dual machine system configuration with the merit of absolutely electrical independence
  • Embedded multiple processor architecture, all processors are mutually independent and parallel running. Moreover, the equipment can equalize load among each processor. In this way, it exploits the merit of distributed multiprocessor system’s parallel processing ability.
