Danfoss VACON NXP Grid Converter


Energy storage and power conversion enabler

The VACON® NXP Grid Converter plays a key role in supporting clean power conversion in distributed networks with or without energy storage.

By enabling connection of energy storage to AC grids, and facilitating AC grids onboard vessels or island applications in remote areas, it fulfils a unique function. Without the grid converter none of these would be possible. 

The grid converter facilitates load sharing and is highly versatile, for easy integration into diverse networks. Its importance cannot be overstated; use of a grid converter is a must in reaching emission targets.

Smart grid converter

VACON NXP Grid Converter for smart grids improves stability in the grid by supporting a diverse range of energy generators and energy storage systems. By enabling peak shaving, it in turn reduces the capital investment required for grid infrastructure. It is certified for grid code compliance in a wide range of countries, for fast system certification for system integrators.
 

Shore supply power conversion

When used with a shore-supply solution, VACON NXP Grid Converter allows electrical power to be sourced from the local grid, rather than the ship’s main engine or generators. This process, sometimes known as ‘cold ironing’, has a significantly positive impact on fuel economy. It causes reductions in CO2, NOx and SOx emissions, as well as noise and vibration levels.

Shaft generator

VACON NXP Grid Converter can also be applied to shaft-generator solutions, ensuring that propulsion machinery is able to operate at various speeds. The shaft generator decouples the shaft from the mains, which allows better electrical quality and improved fuel economy. Additionally, power can either be taken from or entered into the propeller shaft. This is particularly useful for ships that often alternate their speeds as it creates fuel savings and minimizes exhaust emissions by up to 15%. It also creates an emergency mode meaning that the vessel can operate even if the main engine fails.

Support for system integrators

Danfoss supports system integrators (SI) in designing their systems to bid on projects. Our aim is to help customers by providing tools and reference designs to make their system design easier. For instance, Danfoss can provide configurable 3D models as well as 2D general arrangement drawings from our product offering.

Coated circuit boards 
The VLT® AutomationDrive conforms to class 3C2 (IEC 60721-3-3) as standard. If used in especially harsh conditions it is possible to order a special coating that complies with class 3C3.

Ruggedized for extra protection 
The AutomationDrive is available in a ‘ruggedized’ version, that ensures that components remain firmly in place in environments characterized by high degrees of vibration such as marine and mobile equipment.

PM motor support 
Support for any non salient permanent magnet motor for better system efficiency in both VVC+ and FLUX mode.

 

Features and benefits

Intelligent heat management 
Cooling can take place in two ways to offer different sets of benefits. Forced convection cooling: A fan blows cold air through the cooling ribs of the aluminium base to remove heat. The channel is easily cleaned without touching electronics. Cold plate cooling: External cooling is possible through the back side of the aluminium base. Panel through mounting: Electronics inside cabinet - power heat sink outside cabinet. Duct cooling: Air from the control room – or from outside – cools the heat sink without contact to the electronics.

Accessories 
For the VLT® AutomationDrive FC 302 a wide selection of accessories is available to suit your needs. For further details see Operation Instruction.
