Description

Description 

A Generator Step-Up (GSU) Transformer for renewable energy is a specialized power conversion device designed to integrate renewable energy sources (such as wind, solar, hydro, and biomass) into the grid. It converts low-voltage electricity generated by renewable energy generators (typically 0.4kV–35kV) to high-voltage power (110kV–500kV or higher), enabling efficient long-distance transmission and ensuring compatibility with the main power grid. As a critical link between renewable energy systems and the grid, it directly affects the stability, efficiency, and reliability of clean energy delivery, supporting the large-scale integration of green power into global energy networks.

  • 3-ph 60-120MVA, Ynd1, ONAN/ONAF

  • covering products with capacity and voltage level up to 360MVA/330KV.

Features 

  • Adaptability to Fluctuating Loads: Optimized to handle intermittent power output from renewables (e.g., wind speed variations, solar irradiance changes), with strong overload capacity to accommodate sudden spikes in energy generation.

  • Low Loss & High Efficiency: Uses high-performance core materials (e.g., amorphous alloy) and optimized winding designs to minimize no-load and load losses, enhancing overall energy conversion efficiency (often exceeding 98%) to maximize clean energy utilization.

  • Grid Code Compliance: Equipped with harmonic filtering and voltage regulation features to meet strict grid codes (e.g., IEEE 1547, IEC 61400), reducing harmonic distortion and ensuring stable grid integration without disrupting power quality.

  • Environmental & Weather Resistance: For outdoor renewable projects (wind farms, solar parks), it features corrosion-resistant enclosures, IP65-rated protection, and extreme temperature tolerance (-40°C to 50°C), adapting to harsh natural conditions.

  • Compact & Modular Design: Suitable for space-constrained renewable sites (e.g., rooftop solar, offshore wind platforms) with a compact structure; modular components allow easy installation, maintenance, and scalability for future capacity expansion.

  • Smart Monitoring Capabilities: Integrated with IoT sensors to track real-time parameters (temperature, load, insulation status) and support remote diagnostics, aligning with the digital management needs of modern renewable energy plants.

FAQ
Q: What is the capacity range of power transformers up to 345kV, and what are the standardized capacity ratings?
A:
Transformer capacity is strongly related to voltage level, and the capacity range and standard values comply with international general specifications. Details are as follows:
  • Capacity range by voltage level: ① High Voltage (HV, 66kV - 220kV): 5MVA – 250MVA; ② Extra-High Voltage (EHV, 220kV - 400kV): 250MVA – 600MVA+. Higher capacities are usually achieved through forced cooling methods (e.g., ONAF, OFAF).
  • Standardized capacity ratings: Internationally accepted standard capacities include 30MVA, 45MVA, 60MVA, 90MVA, 100MVA, 120MVA, 150MVA, 200MVA, 250MVA, 315MVA, 400MVA, and 500MVA. These ratings are widely adopted in design and production.

  • Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?
    Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I
