Core Functions
Precise automatic synchronization and paralleling of generator sets
Real-time collection of two-phase three-phase voltages, frequencies, and phases, automatic adjustment of the speed and voltage of the generator to be paralleled, enabling seamless grid connection of multiple diesel generator sets without impact, phase synchronization accuracy < 1°, voltage matching accuracy ±0.25%, preventing grid connection impact from damaging the generator and grid equipment.
High-precision electrical parameter collection and measurement
Three-phase voltages, three-phase currents, active/reactive power, power factor, frequency, energy metering, imbalance monitoring, overvoltage, undervoltage, overfrequency, undervoltage, reverse power, overload protection logic.
Multi-generator load distribution control
Cooperates with the main controller to achieve equal distribution of active and reactive loads, avoiding overload of a single generator set and excessive circulating current, supports cross-current compensation, ensuring stable parallel operation of the power station.
Encoder speed collection expansion
Compatible with incremental encoders and rotary transformers for signal connection, accurately collecting engine speed and shaft position signals, used for speed closed-loop control, overspeed protection, speed fault monitoring.
