GE Makes Grid, Wind, Solar Announcements at CIGRE

August 26, 2014 By Karen Henry

General Electric energy manageGE made three energy-related announcements at CIGRE, a global transmission and distribution tradeshow, which is being held August 24–29 in Paris, France.

GE announced that its engineers have tackled grid congestion on Europe’s low voltage networks. Working with UK Power Networks (UKPN) and Scottish & Southern Energy (SSE), GE combined its PowerOn Advantage Advanced Distribution Management System (ADMS) with the Geographical Information Systems (GIS) Smallworld Electric Office, and metering head-end Smart Metering Operational Suite (SMOS), to construct a fully functional low voltage network model. The model provides the platform for power flow analysis, integration of power electronics and advanced automation, improving situational awareness on their networks and enhanced their visibility to network data.

UK Power Networks and Scottish & Southern Energy and are now better positioned to measure power imbalances, dispatch generation and improve customer service levels. The utilities are projecting combined savings of nearly $500M in avoidable capital expenditures.

GE had announced upgrades to its PowerOn ADMS earlier this month.

GE’s Digital Energy business announced that its Synchronous Condenser will be used in First Wind’s Oakfield wind farm in northern Maine to support the public’s demand for wind energy.

Synchronous condensers increase the grid’s strength and improve the voltage stability, allowing a wind turbine to operate in an otherwise weak grid.

The Oakfield wind farm will be completed in the fourth quarter of 2015.

GE’s Digital Energy business also launched its three-phase, PROLEC-GE Solar Pad-Mounted Transformer. The transformer allows the energy coming from the solar inverter and generated by PV cells in solar farms to be transformed from low voltage to medium voltage, which will support the solar industry’s annual growth of 13 percent, GE said. The transformers can be engineered with two low-voltage windings, which enable the user to connect two inverters, helping to decrease the operating cost and initial investment.

The transformer also includes an electrostatic shield as a standard feature, which helps to isolate the low voltage windings from the high-frequency pulses present in the medium voltage system, protecting the solid-state components of the inverters.
