BE Battery Emulator KEY FEATURES FUNCTIONAL DESCRIPTION kw. 2 Quadrant Power Supply. Regenerative up to 100% rated power

Transcription

1 A is a power electronics device that behaves as a real battery pack. CINERGIA s is based on a regenerative power supply. When emulating a battery charge, the energy will be injected back to the electrical grid consuming a sinusoidal current with unity power factor and low harmonic distortion. Using a will save space in the laboratory, avoiding safety issues of real batteries and allow a high flexibility in the tests. FUNCTIONAL DESCRIPTION Operation modes: -Constant Voltage (CV) -Static -Dynamic Three channels: The three channels can be configured independently, allowing emulation of different batteries at the same time The three channels can be configured in parallel, emulating one single battery with 3 times the rated current capabilityv Static mode: the emulated battery voltage will depend on the open-circuit voltage and internal charge and discharge virtual resistance. KEY FEATURES kw 2 Quadrant Power Supply Regenerative up to 100% rated power 1 channel Output: 0 to 750V, 0 to ±555A 3 channels Output: 0 to 750V, 0 to ±A/ch Constant Voltage, Static, and Dynamic modes Dynamic mode: the emulated battery voltage will depend on the State Of Charge, rate of discharge and internal charge and discharge virtual resistance.

2 CONCEPTUAL SCHEMATIC GRID AC EQUIPMENT UNDER TEST (EUT) BACK-TO-BACK TOPOLOGY Recommended The equipment is formed by two IGBT-based power stages: a grid-side Active Rectifier producing sinusoidal currents with low harmonic distortion and close to unity power factor; and three output converters generating three independent channels. Thanks to the bidirectionality of this topology the test energy can be injected back to the grid.
