Queen's University Cogeneration Plant
CHA provided engineering services for the installation and integration of a new cogeneration plant inside an existing central heating plant for supplying power and steam to the university campus and a nearby hospital.
The cogeneration plant consists of two dual fuel Solar Turbines Taurus 70 gas turbine generators, two heat recovery steam generators (HRSGs) with supplemental firing, deaerator, steam dump condenser, emergency diesel generators, 4.16 kV electrical system interconnecting with the university/hospital substation, automatic load shed panel, 44 kV system inter-tie protection/communications, and other plant auxiliaries.
CHA provided design modifications to the existing 20 MVA, 44 kV/4.16 kV KGH substation. The project added new 5 kV circuit breakers to accept the connection of two new 7.2 MW gas turbine generators and modified the existing breaker control circuits and relay protection system to incorporate the new generator synchronizing and automatic load shedding schemes.
