S&C Electric Co. says it has completed the deployment of a VAR compensation system that aims to help the 150 MW Edison Mission Energy Goat Mountain Wind Ranch meet the Electric Reliability Council of Texas' (ERCOT) new grid interconnection requirements.
Retrofit projects, such as the one at Goat Mountain Wind Ranch, are increasing as renewable energy projects and utilities ensure existing assets and systems comply with evolving grid requirements.
S&C's VAR compensation system was retrofitted at the Goat Mountain Wind Ranch near San Angelo, Texas, which is developed and owned by Edison Mission Energy. The retrofit project helps ensure production at the wind farm is not curtailed.
S&C first analyzed the impact of the new requirements for the Goat Mountain plant and then provided a complete engineering, procurement and construction (EPC) solution that addressed the challenges associated with retrofitting a VAR compensation system at an existing plant.
As part of the EPC solution, S&C provided a PureWave DSTATCOM Distributed Static Compensator, which S&C says enables the production of wind energy by allowing plants to meet even the strictest grid codes. The VAR compensation system also includes a mechanically switched capacitor and reactor banks controlled by the PureWave DSTATCOM.
