Development in Storage Applications of Wind and Solar Energy
Published on : Thursday 13-08-2020
New developments in clean, renewable energy show us the path to a sustainable future, and companies are committed to developing applications that will lead the way. For this application, industrial component manufacturers are proposing various energy storage monitoring and management systems consisting of two main platforms and their respective subsystems: the battery cabinet management platform and battery information concentrator. The energy storage system is designed to take advantage of excess energy generated during peak production times, as part of a large energy storage plant, effectively managing the peaks and valleys of wind and solar energy production.
For Instance – Two ICP DAS USA PACs are specified for each part of the system— the battery information concentrator uses VP-25W1 and the battery cabinet management platform uses XP-8341 and both work with the battery management units (BMUs) at the facility.
Each group of systems includes a battery cabinet management platform, under which a maximum of 12 battery information concentrators can be connected. Each battery information concentrator can be connected to a maximum of 18 BMUs.
How ICP DAS USA PACs Works
Each BMU acquires vital data from the battery packs, such as battery power, temperature, SOC & SOH, charging current, and charging voltage. The battery information concentrator then acquires the data from its connected BMUs through CAN Bus interfaces.
After collecting the information from each BMU, the battery information concentrators upload the collected data to the XP-8341 that controls its battery management platform. CAN Bus interfaces be provided to both the battery information concentrator and the battery cabinet management platform through different I-8120W I/O expansion modules.
The battery information concentrator collects data from each BMU, constantly detects the current and voltage signals from the insulation detectors in the battery cabinet —through I-7012F and I-87017W modules— and reports all data back to the battery cabinet management platform at user-scheduled intervals.
The battery cabinet management platform not only manages the status of the battery pack in each battery cabinet but also sends the relevant information to the transmitter through the RS-232 and RS-485 interfaces. In addition, the battery cabinet management platform regularly polls the insulation detectors to determine whether any alarms have been initiated and performs on and off control for the battery relays.
To instantly see the status of each battery cabinet at the site, all the relevant information from each battery cabinet is accessible either through the screen display on the battery cabinet management platform or through the screen for the battery information concentrator built into the VP-25W1 and embedded in the door of each battery cabinet.
Companies in the industry are excited to provide safe and stable energy storage for the green technologies that are powering the feature. We are committed to providing high-quality products and technological solutions that will ensure a bright future.
