Entropea - Power & Control Systems
Entropea’s engineering team develops the architecture of the power systems to condition the electrical power output to match final utilization.
A close collaboration between the departments results in optimum dedicated embedded control systems for the thermodynamic Rankine cycle. High frequency inverters are used for high efficiency energy conversion and industry standard PLCs offer high reliability of the ORC controller. Entropea’s re-gen system is very easily interfaceable with our customer’s PLC via industry standard communication protocols.
Details:
Entropea’s compact heat engine power unit‘s electrical conversion system is based on two back-to-back static power converters. The AFE (Active Front-End) is a power converter that provides bidirectional power flow between the grid and a DC link. With the addition of the LCL EMC filter, the system provides perfectly sinusoidal currents that automatticaly syncronise with the grid. Protectve disconnecting devices are added as part of the PDU (Power Distribution Unit).
The ORC based heat engine system provides power to the turbine wich connected to the generator feeds the DC link through the generator’s VFD (Variable Frequency Drive). In case of grid loss, the PDU automatically disconnects the heat engine power system and the turbine is brought to a controlled stop during which the power is disippated on a braking resistor.
Entropea offers complete solutions for interfacing and transferring power generated by the ORC that suit client’s requirements. Connections to grid or microgrid are possible through dedicated active front ends. Connections through DC bus are also possible. All equipment selected by Entropea will meet relevant standards and regulations.
