PowerSkid™ SyStemSBi-D irect ional ac to Dc inverter/converterS

For 5 kVAC, 15 kVAC, and 34.5 kVAC class grid connected

battery energy storage applications, Dynapower Corporation

offers it’s PowerSkid™ System line of utility grade, bi-directional,

true four-quadrant, Digital Signal Processor (DSP) controlled

inverter/converters. Dynapower’s efficient, flexible and highly

modular PowerSkid™ System optimizes the transfer of energy

between a DC energy storage system and a 3 phase medium

voltage grid.

This integrated package combines a medium voltage step up transformer, system cooling, controls and a full complement of switchgear and protection - including an AC circuit breaker, AC contactors, AC & DC Fusing, DC load break contactors and a DC manual isolation switch - into a single, heavy duty industrial enclosure. This integrated solution yields substantial reduction in Engineering, Procurement, Construction, and Management (EPCM) costs to the customer. The PowerSkid™ provides power conditioning (voltage and frequency support) for intermittent loads and renewable generation.

PowerSkid™ MODES OF OPERATION

The PowerSkid™ provides two modes of operation; Grid-Tied (PQ mode) and Stand-Alone (UF mode). In the Grid -Tied mode, the PowerSkid™ controls the AC output real power (P) and reactive power (Q). In Stand-Alone mode, the PowerSkid™ controls the AC output voltage (U) and frequency (F). The system can be started in either mode and the transfer between modes is done dynamically. Advanced control schemes for multi-unit autonomous and micro-grid applications are available.

SYSTEM CONTROL

Dynapower’s state of the art control and monitoring platform provides operators with both local and remote operation of the system. In the remote operating mode, a communication link provides autonomous operator control via Ethernet, RS232, orRS485.Forlocalcontrol,DynapowerprovidesanOperatorInterfaceTerminal(OIT)forerrorsetcommandsandfullsystem display status.

SYSTEM MONITORINGThe PowerSkid™ provides full system status information including AC output real & reactive power, AC output voltage & frequency, DC battery voltage and DC current readings to the remote operator through feedback signals or through the communication link (via an RTU or PLC). The PowerSkid™ has an on-board monitoring and diagnostics of all subsystems, including cooling, control, safety, interlocks, etc with error history and grid fault data capture. System operating informationisaccessibleontheOITbothlocallyandremotelythrough the communication port.
