Composition of the Integrated Unit:

The step-up converter integrated unit consists of:

High-voltage switchgear cabinet

Power distribution transformer

Auxiliary transformer

Power & communications cabinet

Power Conversion System (PCS)

Technical Specifications:

PCS power ratings: commonly 2750 kVA, 3150 kVA, and 3450 kVA

DC (direct-current) voltage range: for example, 1000 – 1500 Vdc

Maximum DC: e.g., 3508 A, 3740 A, 3872 A

Transformer type: dry-type or oil-immersed

Transformer voltage ratio: e.g., 0.69 / (6 – 35) kV

Protection rating (ingress protection): IP55, IP65

Operating altitude: up to 4000 m above sea level

Communication protocols: Modbus-TCP, IEC 61850, IEC 104

Application Scenarios:

Grid stabilization Mitigates irregularities caused by demand fluctuations and ensures grid stability. During high-load periods, the system can be dispatched (e.g., via AGC, AVC) to support frequency regulation and load-shifting.

Cost saving for large electricity consumers: Large industrial users utilize the system to arbitrage between peak and off-peak electricity rates by charging during low-price periods and discharging during peak times.

Renewable-energy power plants: In large-scale wind or solar plants, the unit can store excess power and then release it smoothly into the grid, helping integrate variable renewable energy.
