Removing the human error for closing the circuit breaker at exact time during power sources synchronization with the grid brought advanced control systems for automatic synchronization.

Synchronization of power sources with the grid is the process of equating the parameters like amplitude, phase and frequency of the power sources and connecting them with the power system network. The control logic calculates the closing time of the circuit breaker and the phase angle increment rate and initiates the closing of circuit breaker.

With the goal to provide a very robust and highly valuable tool we designed one flexible and highly configurable power grid synchronization platform that allows multiple hardware and software configurations.


Building blocks

The SynchroBee unit monitors, protects, connects and synchronizes (when one of the buses is maintained by a diesel generator) two three phase buses. The data can then be sent through analog outputs or communication interfaces for further control, notification or visualization tasks. These can be RMS voltage, RMS current, Active power, Reactive power, frequency, etc.

Using the ZekaTrace™ and ZekaStream™ technology, you will be able to display the electrical characteristics and diagnose the health of the system with an unprecedented resolution for the industry. Only one such converter in your design is enough to change the way you commission the whole power plant.

Having numerous communication interfaces including Ethernet, RS485 and CANBus and utilizing Modbus, makes the integration with your industrial network an easy task. Profibus interface is also available using a Modbus-to-PROFIBUS Gateway. The integrated Modbus master allows different Modbus slaves to be attached to extend IO and functionality.

Several digital and analog inputs and outputs are available for additional programming allowing extra flexibility during the system design or even when the project is in its final phase. The integrated Modbus master allows different Modbus slaves to be attached to extend IO and functionality.

They have already been integrated in some very complex Megawatt power plants and proved to be an extremely valuable tool during the commissioning process. This includes the already operating latest Transocean drillships of type Ultradeep Water including the ones with the first hybrid drill-floor in the world.
