ABB SYN5302a-Z, V217 (Order Number: 3BHB006716R0217) is a digital synchronization device launched by ABB. It belongs to the SYNCHROTACT 5 series and is mainly used for the parallel operation of generators or power grids in the power system, ensuring precise matching of voltage, frequency and phase.
Core function
Automatic synchronization and grid connection:
Voltage matching: Real-time measurement of the voltage difference between the side to be connected (such as the generator) and the grid side. By adjusting the pulse control of the generator’s voltage regulator (AVR), the voltage difference is reduced to the set tolerance range.
Frequency matching: Measurement of the frequency difference (slip rate) between both sides. By adjusting the command pulse to control the generator governor, the frequency difference approaches zero, ensuring consistent frequency during grid connection.
Phase synchronization: Continuous monitoring of the phase angle. Based on the closing time of the main circuit breaker, the lead angle is calculated. At the moment of complete synchronization, a closing command is issued to avoid the impact current caused by phase difference.
Parallel condition monitoring:
Real-time monitoring of parameters such as voltage difference, frequency difference, and phase difference. Only when all parameters are within the safe tolerance range, a closing command is allowed to be issued to prevent accidental operation from damaging equipment.
Multiple instructions and testing functions:
Support for issuing multiple instructions in a synchronous sequence or having a testing function, facilitating debugging and maintenance.
Redundant design:
Some models have an automatic dual-channel synchronization function. Through dual measurement, the reliability of synchronization is improved, ensuring high availability of the system.
