Gamesa Electric
Technology

Gamesa Electric has the necessary know-how, experience and resources to offer cutting-edge inverter technology for large-scale grid-connected solar plants. The 2400+ photovoltaic central inverters installed around the world are a fitting testament to their outstanding performance. Such optimum performance is only possible through absolute control of both the technology and the product

The company began operating in the photovoltaic sector in 1993, when the first 450 kW central photovoltaic inverter was designed and manufactured. The same year, the company rose to the technological forefront through the launch of Europe’s first photovoltaic inverter using 100 kW-capacity IGBT technology, which still remains in operation today

LCoE oriented processes

Gamesa Electric has a comprehensive, LCoE optimized, process for designing, manufacturing, operating and maintaining its central solar PV inverters.

The development and application of cutting-edge technologies are balanced against a solutions cost optimized to maximum robustness, reliability and performance of all models. Research, development and innovation intertwined to form an essential DNA of all the processes and products offered by the company. This is continued throughout a product’s value chain as the company strives to achieve higher satisfaction for its customers

The company product solutions are serviced by an extensive worldwide aftersales service network of employees and partners who understand the advanced control systems and product architecture, minimizing downtime

Test benches
for up to 10MW systems

Markets demand new products with reduced time-to-market goals

Products are required to accomplish with latest grid codes that increase the product performance

Prototype validation before field testing becomes critical to reduce commissioning time and project risks

Renewable energy
market trends

New product size (several MWs) demands high capacity test benches that are hardly accessible

Product customization and component supply development demand test benches with full power capacity.

Electrical drive test benches demand enhanced capabilities such as LVRT (Low Voltage Ride Through), HVRT (High Voltage Ride Through) and Weak Grids

Products tested
SGRE ELE MAD

  • Wind Converters

  • Wind Generators

  • Photovoltaic Inverters

  • Bi-directional Inverters (PCS)
    for battery storage

  • Statcoms (reactive power
    compensation)

Test bench
capabilities

There are two independent wind electrical drive train test benches that can test systems up to 10MW combined.

Two full power test benches available with 3.5MW and 5MW capacity

Upgrade to 6 MW by end of 2019.

Each test bench has:

  • High speed drives made of SGRE ELE products (motors and drives)

  • Virtual grid to perform 50/60Hz, PQVf curve characterization, HVRT/LVRT and weak grid tests

  • Water-cooled systems and close-loop transformers to minimize grid losses consumption.

Testing features

1. Area for WTG electrical system (generator+converter) design validation

  • System control loops tuning

  • Heat run tests for HW validation

  • Efficiency and harmonic tests

2. Water cooling:

  • 4 independent circuits

  • Water temperature regulation for extreme conditions tests

3. Virtual grid:

  • 50/60 Hz

  • PQVf curve tests

  • HVRT / LVRT

  • Weakgrids
