The construction of the Pine Falls Generation Station began in the late 1940s in order to meet the demand for electricity throughout the Province of Manitoba, which had exceeded previous forecasts due to burgeoning agriculture and industry within the province.
Located northeast of the City of Winnipeg, the Pine Falls Generating Station harnesses energy from the Winnipeg River before reaching Lake Winnipeg at Traverse Bay.
In order to improve the reliability of the station, Teshmont provided engineering services to replace the existing Pine Falls Generating Station 115 kV ac switchyard electromechanical protection systems with new redundant microprocessor based protection IEDs, compliant with an IEC 61850 substation automation system architecture.
The protection element replacements project included the upgrading six line protection systems and one bus protection system; with the addition of six new connection protection systems and a new 115 kV breaker failure scheme.
The protection report scope of work included conceptual design work of each element, which included the protection philosophy and functions of each protection IED, I/O assignment, fault calculations, CT validation, generator protection interfacing, communication connections, and alarming requirements. As part of the protection report, single line diagrams, AC connection figures, and dc connection figures were prepared for each element.
The station reliability concerns were addressed at the project’s conclusion. The Pine Falls Generating Station continues to supply power to Manitoba’s grid to this day.
