product introduction

Project Overview

This comprehensive Offshore / Island Power System is a professional-grade turnkey solution engineered for extreme coastal environments. From DC power aggregation to 35kV High-Voltage Metering Switchgear interconnection, our system ensures stable Remote Area Power Supply (RAPS) and efficient energy management.

Our Anti-Corrosion Solar Solutions are specifically designed for Microgrid Interconnection, successfully overcoming technical challenges such as high salt spray, extreme humidity, and the grid fluctuations common in island environments.

Core Components & Technical Details

A. 35kV High-Voltage Metering Switchgear (1 Unit)

Working Principle: Utilizes high-precision Voltage Transformers (PT) and Current Transformers (CT) to step down 35kV signals for 0.2s class energy metering. The system captures real-time busbar power data via electromagnetic induction.

Core Function: Acts as the "Revenue Gatekeeper," providing legal-grade data for PPA (Power Purchase Agreement) billing and high-voltage grid monitoring.

Application Scenario: Installed at the grid-tie point of utility-scale solar farms for precise revenue settlement with the utility company.

B. Grid-Tied AC Distribution Cabinet (4 Units)

Working Principle: This MCCB Protection Panel monitors grid frequency and voltage in real-time. Integrated with ABB/CHINT industrial breakers, it executes smart grid-syncing or millisecond-level disconnection (Anti-Islanding) during grid outages.

Core Function: Automated grid-tie control, millisecond-level Anti-Islanding Protection, and AC-side overcurrent/short-circuit protection.

Application Scenario: The essential bridge between solar inverters and the main transformer within a Microgrid Interconnection.

C. Solar PV Combiner Box / DC Distribution Panel (3 Units)

Working Principle: Consolidates multiple DC strings from the PV array onto heavy-duty T2 Copper Busbars. It uses Hall-effect sensors to monitor the current of each string and uploads data via RS485.

Core Function: High-efficiency Busbar Power Distribution with multi-channel DC fuses and surge protective devices (SPD) to prevent reverse current and lightning damage.

Appliation Scenario: Primary DC collection for centralized solar arrays in offshore or high-salinity environments.

Why Choose Our Island Solutions?

Salt Spray Resistant Switchboard: Every unit is housed in a premium Stainless Steel Electrical Enclosure (SS304/316L) with specialized anti-corrosion coatings. Rated IP65, these enclosures are built to withstand corrosive sea breezes for a 25-year service life.

Tier-1 Brand Integration: We utilize ABB and CHINT components to guarantee global reliability. For international buyers, this ensures easy access to spare parts and familiar maintenance protocols worldwide.

Smart Grid Adaptability: Specifically tuned for island grid stability, our protective relaying prevents voltage fluctuations from impacting local electrical infrastructure.

Moduar & Pre-wired Delivery: All units are factory-integrated and fully tested for "Plug-and-Play" deployment, significantly reducing on-site installation time and expensive labor costs in remote areas.
