Behavior of Capstone and Honeywell Microturbine Generators During Load Changes 4.3 Test Procedure The MTG under test was started and kilowatt load was applied by the load bank. Step changes in kilowatt and kVAR load were then made. Tests were conducted for both increases and decreases in load. The step sizes of the load changes were varied to determine the effects of increasing and decreasing load. During these tests, all available parameters were recorded from the MTGs. All electrical parameters (both single-phase and three-phase) were recorded at the load banks by the Amprobe. 4.4 Analysis The first step in the analysis was to match the data set taken by the Amprobe data logger with the data set collected directly from the MTG. For the Capstone MTG, each data point in the two- second-interval data file was doubled, creating a data set that could be combined with the Amprobe one-second-interval data. The Honeywell data set had been recorded at one-second intervals, so it could be directly combined with the Amprobe data. Duplicate data records were also removed from the Honeywell and Capstone files. Because the clocks of the MTG and Amprobe instruments were not synchronized, the two data sets needed to be lined up according to time. Once the data set had been cleaned up, graphs of the results could be prepared. Both turbines tested are capable of starting from their own internal batteries with no outside power required. Once started, the turbines are capable of supplying loads that have both real and reactive power requirements. The following table lists the rated capabilities of each microturbine based on available literature and conversations with each manufacturer. Table 12.
