SID-2AS(B)
Multiplex Synchronizer

SID‑2AS(B) is a high-reliability microprocessor-based synchronizing controller designed for single synchronizing point applications, ideal for fast and safe grid connection of generators, synchronous condensers, and similar equipment.

It features automatic detection of slip-frequency and dead-bus modes, automatic phase angle compensation, frequency and voltage control, overvoltage protection, and more—ensuring an efficient, stable, and secure synchronization process.

Built with a high-redundancy hardware and software architecture, it supports multiple communication protocols including Modbus and IEC 103, and includes event recording and disturbance capture capabilities. With a bilingual (Chinese/English) user interface and one-touch sequence control, SID‑2AS(B) is the ideal solution for precise synchronization in single-unit or small-scale power systems.

Main Functions
  • (1)
    Automatically identifies the nature of grid connection: slip-frequency or dead-bus synchronization
  • (2)
    Supports high-quality automatic voltage regulation (AVR) and frequency regulation (governor control) for generator sets
  • (3)
    Built-in phase angle correction compensates for inherent phase differences between synchronization voltages
  • (4)
    Enables rapid and stable grid connection for synchronous condensers
  • (5)
    Synchronization is blocked if abnormal frequency deviation is detected, ensuring system protection
  • (6)
    Provides reliable overvoltage protection during grid connection processes
  • (7)
    Supports automatic dead-bus closing under both single-side and dual-side voltage loss conditions
  • (8)
    All operational events are recorded and stored for traceability and diagnostics
  • (9)
    Supports full waveform recording during synchronization; data can be analyzed using supervisory software
  • (10)
    Visualization of live synchronization data with real-time transmission to SCADA or cloud platforms
  • (11)
    Supports B-code time synchronization and communication via Modbus, IEC 103, and other standard protocols
  • (12)
    External printer configuration available to output event logs or synchronization reports as required
