Step-up Storage Converter
Product Overview ：
The energy storage step-up & converter integrated cabin is a highly integrated prefabricated core device for energy storage systems. It integrates PCS power converters, step-up transformers, high and low voltage power distribution, intelligent environmental control, fire protection and energy monitoring systems into a standard container. It realizes bidirectional charge-discharge power conversion, voltage step-up and smooth grid connection. Capable of peak shaving, valley filling, frequency and voltage regulation, it effectively stabilizes fluctuating new energy power generation. Fully pre-tested in factory, the cabin supports rapid on-site deployment for large-scale energy storage projects.
Typical Applications:
Large-scale centralized energy storage power stations, wind-solar-storage integrated projects, grid-side peak and frequency regulation energy storage, industrial and commercial distributed energy storage systems, off-grid microgrid energy storage stations, independent power supply for islands and remote areas, new energy power curtailment consumption projects, and standardized upgrading of existing energy storage projects.
Technical Features:
1. Integrated Converter & Step-up Design
Integrates PCS modules, dry-type step-up transformers and power distribution units into one compact container. Standard modular structure reduces on-site occupation, wiring and construction costs, realizing standardized energy storage system construction.
2. High-efficiency Power Conversion
Adopts advanced three-level topology to ensure high overall conversion efficiency and minimize power loss during charging and discharging. Supports multi-unit parallel expansion to meet MW and hundred-MW level large-scale energy storage station requirements.
3. Multi-mode Intelligent Operation
Supports multiple operation modes including PQ grid-tied, VF off-grid and VSG virtual synchronous generator modes. It adapts to grid stabilization, off-grid independent power supply and black start support for diverse energy storage working conditions.
4. Comprehensive Safety Protection System
Equipped with intelligent fire protection, temperature and humidity control, lightning protection, over-load, short-circuit, over-temperature and insulation monitoring functions. Automatic alarm and interlock shutdown ensure reliable and safe long-term operation.
5. Excellent Environmental Adaptability
Designed with high-level protection and anti-corrosion performance. It operates stably under harsh outdoor environments such as high altitude, extreme temperature, salt spray and strong wind, achieving all-weather reliable operation.
6. Intelligent Remote Monitoring & O&M
Built-in EMS energy management system and touch screen terminal monitor core operating parameters in real time. Supports MODBUS and RS485 communication for remote data monitoring, parameter debugging, fault tracing and cluster operation management.
7. Rapid Deployment & Low Lifecycle Cost
Fully pre-assembled and pre-commissioned in factory, requiring only simple on-site wiring for grid connection. It greatly shortens project construction cycles and reduces later operation and maintenance costs for energy storage projects.
