Custom Size 630~2500KVA Box Type Substation For Photovoltaic Wind Power Station

The Special Box-Type Substation for Photovoltaic and Wind Power is a specialized, pre-installed power hub designed to meet the unique demands of the renewable energy sector. It serves as a critical "step-up" station, taking the low-voltage output from solar inverters or wind turbine converters (typically 315V, 480V, or 690V) and stepping it up to 11kV, 22kV, or 33kV for grid transmission.

Unlike standard distribution substations, this series is engineered to handle the harmonic fluctuations and load cycles inherent in renewable energy generation. The "All-in-One" design integrates high-voltage switchgear, a low-loss transformer, and a low-voltage collection cabinet into a single, weather-resistant enclosure, providing a "Plug-and-Play" solution for remote energy sites.

• Optimized for Inverter Integration: Specifically designed to interface with centralized or string inverters, featuring specialized low-voltage side protections to manage harmonic currents.

• High-Efficiency Step-Up Transformer: Utilizes low-loss (S11/S13/SH15) oil-immersed or dry-type transformers to maximize the energy yield from the PV array or wind cluster.

• Corrosion-Resistant Outdoor Enclosure: Constructed from Aluminum-Zinc alloy or Stainless Steel with an IP54 rating, designed to withstand the harsh UV exposure and dust found in open-field solar farms.

• Intelligent Grid Monitoring: Includes smart RTUs and communication gateways (Modbus/IEC 61850) for real-time remote monitoring of power quality, transformer oil temperature, and breaker status via SCADA.

• Rapid Deployment: Factory-assembled and pre-commissioned, reducing on-site construction time by up to 70% and ensuring immediate grid synchronization.

1. Utility-Scale Solar Farms: Step-up substation for centralized inverter stations in large PV arrays.

2. Onshore Wind Power: Collection and step-up hub for wind turbine clusters.

3. Distributed Energy Resources (DER): Grid-entry point for commercial and industrial (C&I) solar installations.

4. Energy Storage Systems (BESS): Managing the power conversion and grid interface for large-scale battery storage.

• Thermal Management for High Loads: Features intelligent, temperature-controlled forced-air cooling to maintain stability during peak solar hours or high-wind events.

• Safety First Interlocking: Equipped with a mechanical "Five-Prevention" system to protect personnel during maintenance in remote, unmanned locations.

• Customizable LV Collection: We can configure the low-voltage side with multiple incoming feeders to accommodate various inverter configurations.

• Harsh Environment Engineering: Designed for high-altitude (up to 4000m) and high-temperature environments, ensuring reliable performance in deserts or mountain regions.

Q: Can this substation handle 690V input from wind turbines?

A: Yes. We offer specialized configurations for 690V and other non-standard voltages specifically for the wind and PV inverter market.

Q: Is the transformer protected against fire in remote areas?

A: Every unit is built with fire-resistant barriers between compartments. For oil-immersed transformers, we include an integrated oil-leakage sump to prevent environmental contamination.

Q: How does the system communicate with the central control room?

A: The substation includes a digital gateway supporting Ethernet or Fiber Optic connections, allowing for full visibility of all electrical parameters through your SCADA system.
