1500 kW ENERGY STORAGE INVERTER FOR UTILITY SCALE APPLICATIONS

For 480 VAC class grid connected battery energy storage applications, Dynapower Company offers the CPS-1500, a 1500 kW energy storage inverter from the Compact Power Systems™ (CPS) family of utility grade, bi-directional, true four-quadrant, Digital Signal Processor (DSP) controlled inverter/converters. Dynapower’s flexible and highly modular CPS units optimize the transfer of energy between a DC energy storage system and a 3 phase grid. The CPS-1500 provides power conditioning (voltage and frequency support) for intermittent loads and renewable generation. Systems are available in indoor and outdoor configurations.

The CPS-1500 integrates system cooling, controls and a full complement of switchgear and protection including an AC circuit breaker, AC contractors, AC & DC Fusing, DC load break contractors, a DC manual isolation switch into a single, heavy duty industrial enclosure. This offers end users and energy storage integrators a cost advantage when compared to non-integrated systems that require additional add-on items.

KEY TECHNOLOGY

Dynamic Transfer — Dynapower’s proprietary algorithm monitors the grid stability. Upon detecting a grid disturbance, the system will disconnect from the grid connection and transition to stand-alone mode on the load connection. The transition is seamless to the critical loads and supports full load imbalances.

TWO MODES OF OPERATION
The CPS-1500 provides two modes of operation — Grid-Tied (PQ-mode) and Stand-Alone (UF mode). In the Grid-Tied mode, the CPS-1500 controls the AC output real power (P) and reactive power (Q). In Stand-Alone mode, it 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 controls schemes for multi-unit and microgrid 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, or RS485. For local control, Dynapower provides an Operator Interface Terminal (OIT) for error set commands and full system display status.

COMPREHENSIVE SYSTEM MONITORING
The CPS-1500 provides full system status information including AC output real & reactive power, AC output voltage & frequency and DC battery voltage and DC current readings to the remote operator through feedback signals or through the communication link (via an RTU or PLC). It has an on-board monitoring system with error history and grid fault data capture. System operating information is displayed on the OIT in both local and remote modes of operation.

DUAL COOLING
The standard cooling system utilizes both liquid and air-cooling. An internal liquid cooling loop provides cooling to AC epoxy cast inductors and IGBT heat sinks. Air-cooling of the enclosure is accomplished using temperature-controlled exhaust fans with air intake via louvers at the base of each door. Sealed systems incorporating closed loop cooling solutions, including water-to-water and water-to-air options are available.
