Information
The university campus microgrid accommodates two Mitsubishi MF-111 Gas Turbines. Both gas turbines are single shaft and have nominal operating speeds of 9,660 RPM, reduced to 3,600 RPM by means of a reduction gear. The generator is a two pole machine, rated at 15,000 kW, 13.8 kV at 0.90 lagging power factor while operating at 60 Hz. The excitation system of the generator is a shaft mounted main and pilot permanent magnet brushless exciter with rotating fused diodes. The turbine governor is a Woodward 2301A Dual Fuel Control. The campus also accomodates a steam turbine unit. The unit is comprised of a Siemens Dresser-Rand steam turbine, connected via rotor to a Kato Engineering Synchronous Generator. The generator is a brushless field revolving generator with direct connected rotating brushless exciter. The turbine's nominal operating speed is 4,700 RPM, with a single reduction parallel shaft speed reducer that decreases the rotor speed to 1,800 RPM. The generator construction is defined by a four-pole machine, with a nominal power of 3,580 kW, 13.8 kV at 0.8 lagging power factor, operating at 60 Hz. The microgrid also has solar farm. The university campus microgrid has five distinct photovoltaic systems (PV) spread through the microgrid, ranging from a few kW to roughly 900 kW in nominal power. The terminal voltage of the photovoltaic installation is 0.6 kV, which is increased to 13.8 kV by means of a step-up transformer (to match the microgrid's voltage magnitude).
