Shirley Wind Farm Utility Interconnect and Collector System Design
Green Bay, Wisconsin

The Shirley Wind Farm project, located southeast of Green Bay, Wisconsin was a combined substation interconnect and wind park collector system design. The project entailed all aspects of a wind park interconnection to a Local Distribution Company (LDC) including, but not limited to the following: submitting utility interconnect application, designing and developing electrical and physical substation drawings, SCADA design, material specifications, system studies (i.e. reactive power/load flow, short circuit, arc flash, insulation coordination etc.). The project was also comprised of the underground collector system primary cable design to the wind turbines.

The Shirley Wind Farm project appeared to be a typical wind park substation and collector system design. However, this was an engineer/procure/construct project (EPC) managed by the construction team and the design quickly escalated into a project with many entities involved. Likewise, many of the parties involved were financial investors with little technical skills in the distributed generation or utility industry standards. This resulted in Realtime Utility Engineers assisting the financial investors and general contractors on engineering cost effective technical solutions pertaining to capital investments necessary to construct and connect functionally to the LDC. Furthermore, the wind turbines and their respective control system(s) were purchased a year in advance of the design engineering phase, and were designed in Europe to IEC standards as opposed to ANSI standards – this introduced a unique set of challenges. Ultimately, Realtime Utility Engineers designed the interconnect substation to interface with the wind park within IEC standards and the interconnection to the utility within ANSI standards to meet the needs of the client.
