RCS-9659 is a digital synchronizer that determines the proper time to initiate closing of circuit breaker to parallel a generator and bus, or to reclose a line. In order to fulfill different application requirements, it offers three synchronizing modes:automatic synchronizing, semi-automatic synchronizing and manual synchronizing. By monitoring frequency, voltage and phase angle, the RCS-9659 provides correction signals to the governor of prime mover and voltage regulator of generator for voltage matching and frequency matching.

  • Automatic synchronizing (25A)
  • Semi-automatic synchronizing (25SA)
  • Manual synchronizing (25M)
  • Multi-generator paralleling solution: capability of 10 circuit breakers’ synchronization. To any of the circuit breakers, frequency and voltage regulation can be done separately.
  • Remote/local control paralleling mode
  • Blocking signal to other equipments
  • Receive blocking signal from other equipments
  • Communicate with substation automation system via serial port on IEC60870-5-103 or Ethernet port based on IEC60870-5-103 or IEC61850.
  • GPS clock synchronization – message, PPS (pulse per second), PPM (pulse per minute), and IRIG-B synchronization.
  • Oscillograph, 8 cycles ahead of closing signal and 2 cycles after closing signal.

  • Frequency tracking technology is adopted. By the aid of that, real-time value of frequency, voltage and phase are calculated with high precision on every sampling point.
  • The equipment uses an integral front panel and closed cabinet. High and low level signals are separated strictly. With well designed software anti-EMI facilities, the equipment’s capability of interference immunity is highly enhanced. Furthermore, its electromagnetic radiation also satisfies relevant international standards.
  • Flexible communication function - 2 RS-485 communication rear ports conform to IEC 60870-5-103 protocol - 1 RS-485 communication rear ports for clock synchronization - 4 rear Ethernet ports (optional), IEC 61850
  • Monitoring and Metering - Event Recorder including 64 reports of status change of binary input, 64 self-supervision reports and 256 operating reports. - Disturbance recorder including 64 fault reports, and 24 waveforms (The file format of disturbance recorder is compatible with international COMTRADE file.)
  • Friendly Human Machine interface User Interface - 1 RS-232 communication faceplate port for testing and setting - 1 RS-232 communication rear ports or RS-485 for printer
