GE has introduced a one-megawatt (MW) solar inverter that is available in both 50- and 60-hertz versions, making it suitable for applications worldwide. Like GE’s existing 700-kilowatt solar inverter, the new ‘Brilliance’ solar inverter is based on the proven power converter technology that GE uses for its global fleet of wind turbines. Building on a platform of power electronics, including the monitoring and controls that enhance wind energy grid integration, GE’s solar inverters include grid-friendly features that deliver performance in large-scale solar installations similar to conventional power plants.
Problem
As renewable energy penetration increases, so too will the challenge to effectively integrate these larger solar projects into the grid by providing grid reliability.
Solution
To ensure that solar power plants stay online during grid disturbances, GE’s solar inverters include control functions that enhance integration. Similar to GE’s wind turbine controls, which have been designed to meet evolving grid codes in the wind industry, GE’s suite of solar plant monitoring and controls can manage voltage in anticipation of future regulations. All of GE’s solar solutions, including the 1 MW Brilliance solar inverter includes a competitive GE warranty backed by the resources and expertise of GE’s global service network.
Applications
Utility-scale PV power plants.
Platform
The GE inverter utilizes a two-stage power conversion approach, which provides a standard 480vac output voltage, eliminating the need for an intermediate transformer, resulting in higher conversion efficiency compared to a single-stage power conversion system. If multiple inverters are connected to a medium voltage grid, a standard medium voltage transformer can be used. Fitted with a robust outdoor-rated enclosure, the Brilliance Solar Inverter has been designed to perform even in extreme environmental conditions. GE’s Solar SCADA application is included in the SunIQ system and provides a broad set of intuitive tools for a secure, real-time view of a solar plant’s operation and maintenance.
Availability
October 2010 onwards.
