One of the World's Largest Wind Farms Takes Advantage of ETAP Power System Monitoring, Predictive Simulation and Event Playback

Irvine, Calif. – June 13, 2011 – Operation Technology, Inc. (OTI), developer of ETAP enterprise solution for electrical power systems, announces that the Colorado Green Wind Power Project, a joint venture of Iberdrola Renewables and Shell Energy, is using ETAP Real-Time™.

The Colorado Green Wind Farm was originally modeled and designed with ETAP power systems software. Existing electrical telemetry devices were connected to the ETAP intelligent one-line diagram and metering elements, such as GE Universal Relays, were added to the offline model. This system configuration allows the ETAP Real-Time system to continuously capture and record wind farm operating data. The system detects potential threats by determining the source of potential problems and advises on corrective actions to avoid interruptions and the costs associated with them.

The issue of wind farms losing interconnection with the power grid due to power quality issues is common to a number of wind projects throughout the world. Each time a wind farm disconnects from the power grid, generation is unavailable for a significant period. ETAP Real-Time monitors the voltages and power flows throughout the wind farm network and combines ETAP simulation tools to assist operators in understanding the events that caused an outage. Thereafter, it can test and verify the appropriateness of the solution prior to deploying any changes.

Root cause & effect analysis tools were supplied in order to perform a faster power system triage. With complete system visibility through monitoring and integrated predictive simulation tools, ETAP Real-Time can quickly analyze and provide feedback to the wind farm operator who can then implement appropriate countermeasures.

“Stringent regulations imposed by grid operators require wind farms to guarantee a secure power supply,” states Tanuj Khandelwal, Director of ETAP Automation, “which necessitates state-of-the-art, open and flexible technology that goes beyond conventional power monitoring. Therefore, it is vital for wind farm owners and operators to take steps to implement an intelligent real-time system.”

About Colorado Green Wind Power Project
The 162 megawatt Colorado Green Wind Power Project, located 20 miles south of the Town of Lamar, was developed to help meet Colorado’s demand for renewable electricity.  The project utilizes 108 General Electric 1.5 MW wind turbines and is owned by Iberdrola Renewables and Shell WindEnergy Inc. in a 50/50 joint venture.  According to American Wind Energy Association calculations, the project provides enough renewable electricity to serve approximately 52,000 average homes each year.
