  • PCS-9659 Synchronizer

  • PCS-9659 is a digital synchronizer that determines the proper time to initiate closing of the 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 PCS-9659 provides correction signals to the governor of prime mover and voltage regulator of generator for voltage matching and frequency matching.

Communications
  • Up to four 10Base-T/100Base-TX (RJ45) ports or two 100Base-FX ports with IEC 61850-8-1 MMS for non-timecritical message, IEC 60870-5-103 over TCP/IP or MODBUS TCP.
  • Two RS-485 rear ports with IEC 60870-5-103 or MODBUS RTU.
  • One RS-485 rear port for clock synchronization
  • One RS-232 rear port for printer
  • 1 faceplate RJ45 port for testing and setting
  • Clock synchronization via pulse, IRIG-B and SNTP
  • 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.
