Product Description

Product Description

PCS and transformer integrated All in one

The PCS transformer integrated unit is the "energy conversion and grid connection hub" of the energy storage system. It receives the low-voltage direct current output from the battery cluster, converts it into alternating current through the PCS, and then boosts it to the medium and high voltages required by the grid through the built-in step-up transformer, directly achieving grid connection power supply without the need for an additional independent step-up cabinet.

Core advantages:

High integration level:

Integrates core components such as PCS, step-up transformers, and switchgear, reducing connection links between devices and minimizing fault points.

Small footprint:
Compared to the split-type solution, the volume is reduced by 30% - 50%, significantly saving installation space in data centers or containers, and suitable for scenarios with limited land resources.

Better cost and efficiency:
Reduces direct costs for equipment procurement, installation, and wiring, while reducing line losses, and improves the overall system efficiency by 1% - 3%.

Easier operation and maintenance:
Unified design, unified debugging, and unified monitoring reduce the complexity of multi-device collaborative maintenance and shorten the time for troubleshooting.

PCS

Bidirectional energy conversion:
During charging, it converts grid AC power into the required DC power for the battery; during discharging, it converts the battery DC power into grid-compatible AC power

Intelligent charging and discharging control:
Precisely controls charging and discharging power according to EMS instructions, achieving optimized management of battery SOC/SOH

Power quality regulation:
Provides reactive power compensation, harmonic control, improving grid stability

Grid support:
Achieves low voltage ride-through (LVRT), frequency regulation, enhancing grid resilience
 

Transformer:

Voltage matching:
Converts the low-voltage AC power (400V-800V) output by PCS to the grid
connection voltage

Electrical isolation:
Prevents grid faults from affecting the energy storage system, improving safety

Energy transmission:
Efficiently transmits energy, reducing transmission losses
 

Communication power cabinet:

System control center:
Integrates PCS controller, EMS/BMS communication module, achieving "three remote" (telemetry / signaling / remote control)

Data collection and processing:
Real-time monitors operating parameters (voltage / current / temperature) and uploads to the backend

Power supply management:
Provides stable AC/DC power for control systems, protection devices

Network connection:
Supports multiple communication protocols, enabling remote monitoring

 

Auxiliary Transformer:

Power conversion:
Takes power from the main circuit, converting high or medium voltage to low voltage (380V/220V)

Control power:
Provides stable working power for PCS control system, cooling system, lighting, etc. auxiliary equipment

Electrical isolation:
Ensures isolation of control circuits from the main circuits, improving system safety
 

High-voltage cabinet:

Power distribution:
Safely distributes the high-voltage power output by the boost transformer to the grid connection point

Circuit protection:
Configures circuit breakers, fuses to achieve short circuit / overload / overvoltage protection

Measurement and monitoring:
Integrates current / voltage transformers to provide data for protection and metering

Safety isolation:
Configures disconnect switches and grounding switches to ensure maintenance safety
 

The energy storage PCS transformer integrated unit achieves a "one-stop" energy hub from battery to grid through the perfect synergy of five core components.

The PCS is responsible for energy conversion and intelligent control, the transformer realizes voltage matching and electrical isolation, the communication cabinet provides the "neural center" function, the auxiliary transformer ensures the stability of the control system, and the high-voltage outgoing cabinet ensures the safety of the grid connection.

This highly integrated design not only significantly improves system performance and reliability, but also simplifies engineering implementation, reduces the total life cycle cost, and becomes an ideal choice for industrial and commercial energy storage, grid frequency modulation and other scenarios.
