Core Functions
Precise Synchronous Grid Connection of Generator
Real-time collection of voltage, frequency, and phase signals on the generator side and the grid side, automatically outputting acceleration/deceleration, voltage increase/voltage decrease pulse instructions, adjusting the generator speed and terminal voltage, when the voltage difference, frequency difference, and phase difference meet the set threshold, according to the inherent closing time of the circuit breaker, calculate the closing lead angle, precisely issue the closing instruction, achieving zero-impact grid connection.
Automatic + Manual Dual Modes
Full automatic one-click grid connection; also supports on-site manual voltage and frequency adjustment, single-side synchronous check, suitable for generator start-stop debugging, maintenance grid connection scenarios.
Multiple Safety Protection for Grid Connection Lockout
Directly lock the closing output when voltage exceeds limit, frequency exceeds limit, frequency difference is too large, loss of voltage, PT disconnection, to prevent non-synchronous grid connection from causing generator impact damage and grid oscillation accidents; equipped with closing timeout, multiple grid connection failures lockout protection functions.
Event Recording and Fault Alarm
Record grid connection time, synchronous parameters, tripping lockout reasons, PT abnormalities, etc. SOE events, panel LCD + status indicator lights intuitively display operation, synchronization, fault, adjustment status.
Communication Remote Transmission Function
Support Modbus, LON, Profibus bus communication, can upload grid connection status, voltage and frequency parameters, fault alarm to power plant DCS, background monitoring system, realize remote monitoring and remote switching of synchronous device.
