II SYNCHROTACT ® 5 device application scenarios

Mainly used in power plants, self owned power generation industrial facilities, to achieve grid connection between generators and power grids/islanded lines, and also used in distribution systems. If the voltage, frequency, and phase are not synchronized and closed, it can cause line faults, generator overload, and in severe cases, damage to the generator. Supports three core working modes:

Automatic synchronization and grid connection of the generator to the power grid: output regulation pulses to the AVR automatic voltage regulator and GV speed controller, regulate voltage and frequency, and issue closing commands when conditions are met;

Automatic parallel connection between lines and busbars (synchronous/asynchronous circuits);

Synchrocheck monitoring mode: monitoring manual/automatic grid connection operations, supporting permission for closing dead bus without voltage.

Typical application wiring

Simultaneous inspection between simple lines;

Simultaneous verification and monitoring of manual grid connection;

Generator fully automatic synchronization;

With the help of auxiliary unit SYN5500, one host completes the synchronous switching of two circuit breakers.

Working principle

The entire synchronous logic is divided into four functional modules:

Measurement module: Collect U1 (system side) and U2 (standby side), calculate voltage difference Δ U, slip s (frequency difference), and phase angle α;

Matching regulation module: Output regulation pulses, regulate AVR voltage and speed regulation, reduce voltage and frequency differences;

Grid connection condition monitoring: Compare the measured values with the set limits, and if Δ U, s, and α all meet the conditions simultaneously, output CHK RELASE closing permission;

Generation of closing command: Considering the closing time of the circuit breaker, calculate the lead angle α v, and output the closing CMD when the phase reaches the lead angle and the permission is valid; Under steady-state synchronization, if the conditions are continuously met during the monitoring time, the command will be directly output.

Simultaneous inspection mode: Only enable measurement+condition monitoring, no voltage or frequency regulation, only output closing permission relay contacts.

Hardware model family (SYN-5xxx series)

Key Features of Model Core Functions

SYN 5100 only checks DIN rail installation synchronously with Synchrocheck, with only one set of parameter set and no automatic voltage and frequency regulation

SYN-5200 synchronous inspection/simple automatic grid connection, no matching regulator supports 7 sets of parameter sets, supports communication interfaces

SYN-5201 single channel fully automatic synchronization with voltage and frequency matching adjustment

SYN-5202 dual channel automatic synchronization with two independent software and hardware channels, connected in series to enhance the safety of preventing false closing

SYN   5302 The chassis is equipped with two complete sets of SYN5202, and one of the four output contacts can be bypassed internally. If one set fails, the other set will automatically take over, balancing safety and operational availability without the need for external redundant devices

Key selection points:

Low cost per channel; Dual channel with different software and hardware architectures, with extremely low probability of simultaneous failures, to avoid major equipment damage caused by grid connection errors;

SYN5302 integrates two complete dual channel systems into the same chassis, eliminating the need for external redundant cabinet wiring and engineering design.

Parameter set capability

Version with 7 parameter sets: stores 7 sets of independent and complete synchronous fixed values, corresponding to 7 different circuit breakers; By selecting parameter sets/synchronization points through numerical input, the software binds parameters with corresponding devices to avoid mismatched fixed values.
