Protection and control for battery and energy storage systems
For BESS and other energy storage systems, SYMAP® solutions cover the protection, metering, control and communication layer for land-based and marine battery applications. For land-based BESS plants, the focus is on the AC side of the connection, PCC metering, PCS/inverter transformers, MV busbars, feeder cells, Grid Code functions and communication with SCADA, EMS or PPC systems.
For the AC grid connection of a BESS plant, SYMAP® Compact+ GC is considered for network and system protection, NA functions, grid decoupling, voltage and frequency monitoring and communication on the AC interface. For additional feeder, transformer and auxiliary cells, the corresponding Compact+ or classic SYMAP® variants are considered according to the measurement inputs and cell functions. SYMAP® Compact+ is FGH-certified per VDE-AR-N 4110:2018-11 (medium voltage) and VDE-AR-N 4120:2018-11 (high voltage).
For marine and offshore hybrid BESS applications, SYMAP® BAT and the corresponding SYMAP® marine variants are considered for integration of the battery converter with generator groups, the busbar, the transformer and the supervisory system. The corresponding SYMAP® marine variants are available with type approvals from the leading classification societies according to the selected configuration and application.
On the DC and battery side, the SYMAP® BAT and DC variants together with the corresponding communication interfaces can provide a signal, protection-and-control and communication layer to the BMS/PCS system. SYMAP® is not a replacement for the BMS; it works as part of the overall electrical and control architecture of the plant.
