Caribou Wind Project Caribou, New Brunswick

The Caribou Wind Park represents the 2nd largest wind facility in New Brunswick. The 99 MW wind farm represents a $200 million investment and a 20 year partnership between the Province of New Brunswick and SUEZ Renewable Energy NA.

We worked with the Province. NB Power, and SUEZ Renewable Energy NA throughout construction as the lead engineer for the design of a new control building, substation, communications system and collector system. We also completed protection design, short circuit and coordination studies, relay setting calculations and preparation of the electronic relay setting files for the Utility interconnection substation.

Our work involved design of a complete substation to interconnect with NB Power’s transmission system. This comprised a single bay 138 kV breaker terminal, a 100 MVA step up transformer (34.5 – 138 kV), four 34.5 kV collection system feeder terminals, grounding transformers for collection system, revenue class metering equipment, bus and equipment support structures, lightning/surge protection, layout of DVAR equipment and insulators and bus work. Also included was protection control for the substation equipment and substation automation and communications for the utility, wind turbine and DVAR vendor interfaces.

The substation consists of a 138 kV transmission line, a 138 kV breaker, a 65/87/108 MVA, 13834.5 kV transformer, an 8 MVAR DVAR with four 7.5 MVAR capacitor banks system and four 34.5 kV feeders. The 138 kV transmission line is protected by a SEL351 overcurrent relay. The transformer is protected by a SEL387E transformer management relay. The DVAR bus is protected by a SEL351 overcurrent relay and the DVAR transformer is protected by a SEL501 overcurrent relay. Each capacitor bank is protected by a Basler Neutral Overvoltage relay. Each 34.5 kV feeder is protected by a G&W recloser with a SEL351R as the protection and control relay.

The 34.5kV collector system design involved underground cabling from the base of each V90 wind turbine to a riser pole consisting of cable terminations, fusing and a provision for isolation. The wind turbines are interconnected by four overhead collection feeders, optimally sized and configured to keep the total losses within acceptable limits
