SIVACON 8PS - LDM system for power transmission of renewable energiesThe SIVACON 8PS busbar trunking systems with the LD and LDM systems, have been used successfully in wind turbines for several years. The LDM-P busbar trunking system has now been added to the product family. This system is destined for use in photovoltaic and container stations where extremely high amounts of energy are transmitted in very limited space.
SIVACON 8PS - LDM system for windturbines
Whether you are an investor, wind farm operator, wind turbine planning engineer, or tower manufacturer, the LDM system offers you distinct advantages specific to the design - at no extra cost. Such benefits can include improved unit availability and enhanced safety and reliability during installation and operation, for examble. The LDM busbar trunking system from the SIVACON 8PS product family is thus the innvovative alternative to cables. The LDM system offers reliable and efficient power transmission for currents of up 8,200 A.
SIVACON 8PS - LDM system: cost-efficient planning
The LDM system precisely fulfils the specific needs and requirements of every wind turbine and provides all the necessary components, significantly simplifying system planning. This enables, for example, the rotor and stator runs for double-fed asynchronous generators to be routed within a single housing. A PE conductor can be optionally included in the same routing. What’s more, specialists on Siemens' Wind Power team are there to provide you with expert advice and to support your planning efforts. Hence, you can plan cost-efficiently right from the project start.
SIVACON 8PS - LDM system: efficient installation
Simply join the segments, secure with bolts, and you're done: LDM busbar trunking systems arrive at the project site in pre-assembled segments. Contrary to cables, there's no need for complex cutting to length, stripping, insulating, and screwing into place. All the busbar needs is a support on the tower wall every 3.20 metres. Compare this to cable systems, where spacing must be calculated, with some intervals less than 50 cm.
In addition, busbar elements can be pre-assembled and installed in tower segments that lie horizontally prior to final erection, thereby saving time and money. On site, all that's left to do is secure the connections between the tower segments during final erection using design verified single-bolt connections. The assembly work in all phases of installation is performed using a standard torque wrench. In short: Using the LDM system substantially reduces installation time.
SIVACON 8PS - LDM system: safe and reliable operation
The LDM busbar trunking system transmits power from the nacelle to the tower base safely and reliably. The LDM system meets all requirements of IEC 61439 Parts 1 and 6. This means that the system is subject to priordesign verification, ensures that all technical parameters are sustainably fulfilled, and rules out any overloading of the systems and consequential damage. Any short circuits arising have no impact on the LDM system. Because practically no plastics are used, the fire load is very low, immensely increasing the level of safety compared to cable systems. For wind turbine operators, this translates into reliable wind farm operation – across the entire fleet.
SIVACON 8PS - LDM system: working sustainably
Growing importance is being place on improving the energy efficiency of wind power. Manufacturers and operators of wind turbines are coming under pressure to design their units to be as low-loss as possible. With LDM system, Siemens has developed a system that minimises power losses and significantly improves efficiency.
Over the total service life of a wind turbine, this translates into additional grid feed-in compensation for wind turbine operators. In addition to the quick return on investment, operators using the LDM busbar trunking system demonstrate their sense of responsibility for environmental issues – thanks to the environmentally friendly, halogen-free design, high energy efficiency, and high recycling rate.

SIVACON 8PS - LDM-P system for photovoltaic and container stations
The benefits of the technology over cable-based solutions are particularly apparent in photovoltaic and container stations. These include fast planning and installation, current intensities up to 7,000 amperes (A), and exact adaptation to other necessary products, such as inverters and transformers. Siemens also provides comprehensive support during the planning phase and enables the customer to achieve integrated and thus very efficient power distribution.
