Advanced high-power AC emulator with SCR and X/R configuration capability, integrated RLC-modelling and anti-islanding test modes, user-controlled weak grid condition emulation and pre-compliace test sequence automation as per IEEE and UL standards.
Integrating AC source and AC load functioning into a single unit, TITAN AC Emulator is a bidirectional and full four-quadrant test platform with regenerative technology when operating as load mode for feeding back energy to local utility instead of dissipating as heat, with an outstanding efficiency of up to 94%.
The bidirectional grid interaction capability reduces laboratory HVAC and thermal management cost, while flexibly handling test and validation application regarding grid interoperability, TITAN functions as an ideal test platform for high-intensity, long-duration utility-scale validation and performance validation of grid-forming inverters, high-power energy storage systems and PCS, as well as large-capability UPS or BBU in HVDC AI data center.
While a single set of AC emulator reaches the maximum power of 1MVA, it works as a the fundamental building block for configuring your utility-scale grid code compliance test platform through DMPS technology to reach as maximum as 10MVA power rating, without latency or compromised performance and dynamics.
For users such as certification institutes where requirements and demands are shifting, platform reconfiguration is allowed among the parallelled matrix for splitting a single 10MVA platform in to several subsidiary master-slave systems for multi-output and multi-station testing application setup, without the essentialness of a whole system replacement.
Confronting the latest challenges in grid-forming capabilities as per those testing guidelines specified in IEEE 1547.1-2020 following the update of IEEE 1547-2018 where requirements are proposed for grid-supporting capability of DERs. TITAN AC emulator addresses these challenges with an integrated FPGA-based RLC modelling for achieving independently and dynamically adjustment of Resistance (R), Inductance (L), and Capacitance (C) parameters in real-time - to replicate complex grid conditions and handle applications such as anti-islanding test without engaging additional RLC load banks.
When conducting grid-tied equipment testing with TITAN AC emulator, engineers can configure the Short Circuit Ratio (SCR) and impedance angle (X/R ratio) via the software interface for simulating the specific impedance characteristics of any grid node. The R&D teams may efficiently verify control loop stability and harmonic oscillation suppression under severe conditions, such as extreme grid impedance fluctuations and ultra-low SCR environments.
Targeting the most stringent international distributed energy grid-tied standards, TITAN delivers ready-to-use, pre-compliance-grade testing capabilities. Standards like IEEE 1547.1 2020 and UL 1741 SB demand highly sophisticated grid-support functions from smart inverters (e.g., Volt-VAR, Volt-Watt, Frequency-Watt, ROCOF, etc.). Test engineers no longer has to set up the testing application sequence and do programming from scratch, go-to-market process is accelerated with reduced opportunity cost, your saving and potential earning are achieved with an pre-compliance integrated software.
