Power conversion systems for energy storage Engineering that stores
INDRIVETEC Innovative Drive Technologies AG The Company Indrivetec specialises in development and manufacture of high-performance storage inverters and AC/DC converters for SuperCaps and batteries. Our energy storage systems can be used for charging or discharging the storage media of power supply systems or interconnected systems in addition to isolated networks which supply electrical power to areas which are not connected to the public grid. In regenerative or also generator powered power supply systems, batteries or SuperCaps ensure that high quantities of energy can be supplied, even in short term. We ensure a reliable power supply, even in remote areas from the concept through to commissioning, on behalf of our customers. F l e x C o n v e r t Flexible and versatile power conversion system for energy storage Our inverters are BDEW-certified and comply with today s power supply requirements, even in weak power supply systems Moreover, all devices from Indrivetec can be connected in parallel, i.e. x inverters can be used at the same time in a system, what allows installations to be operated up to power ratings of 100 MW and more.
System Advantages Flexible performance adjusted to each storage technology Fully integrated unit including interface to BMS Cross energy storage compatible Low auxiliary power requirements for minimum OPEX Improved efficiency at partial load for grid services Units for indoor or outdoor installations Closed cooling concept Integrated grid service functionalities Project references as battery power plants and islands Global operational service teams and partners Service hotline
The FlexConvert inverters Therefore are inverters required In order to optimally use energy, especially renewable produced energy, it requires buffers and inverters which function as charging/discharging devices. For instance, batteries and capacitors are used as buffers for the electrical energy. The FlexConvert battery inverter design parameters The inverters are build according IEC/CE and as well UL, others on request. BDEW fault ride through and grid connection requirements are fulfilled. Inverter cabinets are fully enclosed with IP54 or higher, to have protected and defined environmental conditions for the build in components, what ensures high system availability and low maintenance costs. Inverters are fully liquid cooled, equipped with external heat exchangers. Wide range of grid AC voltage or energy storage medium DC voltage available.

SuperCap storage systems Indrivetec low voltage SuperCap storage systems are equipped with DC-DC or DC-AC power conversion and full SuperCap monitoring. The storage can get connected onto DC distribution systems as inverter DC-bus ties or direct connected to AC grids (400 V / 480 V / 690 V). The SuperCap storage is used for fast cycling power compensation / peak load shaving or short term power bridging as e.g. support until a diesel generator gets started. There are three SuperCap storage sizes available: - Power 300 kw, energy content 2.5 MJ, cabinet size L x D x H = 1600 x 1000 x 2500 mm, air cooled - Power 600 kw, energy content 5.0 MJ, cabinet size L x D x H = 2600 x 1000 x 2500 mm, air cooled - Power 900 kw, energy content 7.5 MJ, cabinet size L x D x H = 3600 x 1000 x 2500 mm, air cooled 600 kw SuperCap storage unit as a part of a 3 MW/25 MJ storage for a rollercoaster application in Spain (Q4/2016) 500 kw SuperCap storage unit, installed in Russia in 2014, compensating power fluctuations of an 800 kw compressor 2.5 MW/12. 5 MJ storage system for a linear motor rollercoaster application in Italy (2009)
