Figure 4: Tanker The microturbine generator was connected to an Avtron 1000 kW capacity electrical resistance load bank, with a manual load setting; electric generation quality was measured with a FLUKE 434/PWR energy meter connected to the generator power output through clamp-on current transformers. This is a three-phase electrical power quality analyzer FLUKE 434/PWR with a measurement range Vrms (AC+DC) between 1-1000 V, and frequency range of 40-70 Hz. A schematic of the general layout of the test facility is shown in the figure 5. Figure 5: The procedure followed to assess electrical, thermal, and operational performance of the micro- turbine generator, comprised pretest activities, startup, idle, and a two-step load test during a short period of time. The software for the microturbine unit was configured for standalone operation through the local display panel; the turbine was started, controlled and monitored by a computer using Capstone’s software. The load test applied by the load bank, as it is shown in figure 6, consisted of a transient from idling to a 20-kW load at maximum speed of 96000 min -1 , a steady-state operation in this operation point for about eight minutes, followed by a drop to 3 kW power at 60000 min -1 , and a steady running at this load for about four minutes. In the last part of the test, the load was completed released and the microturbine was sustained idling at a speed of 45000 min -1 , as it is shown in figure 6. During the test, all available parameters were monitored and recorded from the MTG system. All electrical parameters (both single-phase and three- phase) were recorded at the load bank by the energy meter.
