Siemens accepts no liability for deficiencies of or damage to these energy storage devices, or for deficiencies or damage that have been caused by these energy storage devices.
(https:// support.industry.siemens.com/cs/ww/en/view/109773591). The SIMOCRANE ESSM Step 7 library provides operating modes, functions and a standardized interface for the modular design and scalability of an energy storage system in a crane system. SIMOCRANE ESSM also offers a standardized interface to the crane application.
Product description 3.1 Description 3.1.2 Product overview The product SIMOCRANE Energy Storage System Management is a global executable STEP 7 library comprising: • Functions • Function blocks • Data types A license is required for the encrypted core function "LEssMgmt_Main" (see figure below).
An AC island grid can be set up from the DC link controlled by SIMOCRANE ESSM using an "Active Line Module" (ALM) to create the grid, for example. This makes it possible to operate independently of the line supply. The specified charge and discharge power limit is not exceeded.
Page 26
Note You can find details about the dimensioning and application of SINAMICS DCPs in the operating instructions "SINAMICS DCP DC Power Converter" (see section Description of SIMOCRANE Energy Storage System Management (Page 21)). Service function The Service function provides support when commissioning the energy storage system. The Service function allows you to set important parameters, limits and setpoints.

(0-8). All the potentially available SINAMICS DCP units are set up in the hardware configuration of the ESS IF PLC as standard. This is a basic requirement for use of the SIMOCRANE ESSM Step7 library. Should only 2 SINAMICS DCPs be physically present, for example, enter a 2 here. Unused devices in the hardware configuration are deactivated during startup.
Droop control makes parallel connection possible. The droop value determined by the energy storage system [%] (p.54127) must be signaled to SIMOCRANE ESSM. This causes a voltage correction to be applied which is dependent on the actual system power. This is necessary in order to compensate for voltage fluctuations in the DC link due to operation in droop control.
