Product Performance

Sliding synchronization + fixed phase synchronization dual algorithms, pressure difference / frequency difference / phase difference triple locking protection, preventing non-synchronous grid connection impact on the grid, built-in dead bus (dead line) closing function;

YB three-phase full acquisition advantage: adaptable to three-phase unbalanced grids, low-voltage plant power supply, three-phase four-wire self-contained power station, compared with single-phase model, higher sampling accuracy and more comprehensive fault identification;

Automatic compensation of circuit breaker closing delay, can match different mechanical switch closing time difference; built-in SPM-A four operation modes: operation / verification / allowed / shutdown switchable;

Parameter hierarchical password protection, preventing on-site accidental modification, parameters permanently saved after power loss; English / German dual-language system interface;

Fully isolated signal circuits, resistant to electromagnetic interference from frequency converters and high-power motors, adaptable to harsh conditions such as oil and gas, offshore vessels, and marine vessels.

Application Domains

Industrial self-contained power stations: diesel / gas distributed generation units, factory emergency backup power grid connection;

Oil and gas petrochemical industry: oilfield associated gas power generation units, refinery self-contained thermal power plant parallel control;

Hydropower field: small and medium-sized hydro-generator plant power supply, small hydropower station grid connection;

Vessel power: ocean-going vessel auxiliary generator, shore power grid connection control.
