Capstone Turbine Corporation • 21211 Nordhoff Street • Chatsworth • CA 91311 • USA Technical Reference: Capstone Model 330 Electrical Electrical Ratings: Grid Connect Table 1 presents the Electrical Ratings for the Grid Connect configuration. Whenever an expression is listed, N equals the number of individual MicroTurbines within a MultiPac (where1≤ N ≤ 100). See Figure 1. Table 1. Electrical Ratings: Grid Connect Description Single Unit MultiPac Grid Voltage Operating Range Output Voltage Connection Grid Voltage Harmonic Distortion Grid Voltage Balance Grid Voltage Phase Displacement 360 to 528 VAC, (3-phase only) 3 wire, L1, L2, and L3 The grid must comply with IEEE 519. Note 1. Within ± 2% at full load 120 (± 1) degrees Same as Single Unit Same as Single Unit Same as Single Unit Same as Single Unit Same as Single Unit Maximum Grid Impedance ≤ 10% inductive (2 mH) and ≤ 5% resistive (0.4 ohms), Zbase= 7.67 ohms line-to-neutral ≤ 10% inductive (2/N mH) and ≤ 5% resistive (0.4/N ohms), Zbase= 7.67/N ohms line-to-neutral Grid Voltage Phase Rotation Either clockwise or counter- clockwise. Auto synchronization. For Dual Mode applications, the grid voltage phase rotation must be L1, L2, and L3, counter- clockwise. Same as Single Unit Grid Inrush Current @ Disconnect Switch Closure, (per individual unit within a MultiPac) 24 Amps RMS Same as Single Unit Grid Frequency Acquisition Range 45 - 65 Hz. Auto synchronization. The MicroTurbine senses the grid waveform and synchronizes to its phases and frequency before an output connection is made. Same as Single Unit Output Power Output kVA (@ 480 Volts) 0 (Note 2) to 30 kW HP and liquid fuel. 0 to 28 kW low pressure fuel 38.2 kVA 0 to kW = 0.95*Σ (kW30HP* N30HP, kW30LP* N30LP) (Note 3) N*38.2 kVA Note 1: Total harmonic voltage must be less than 5% (13.85 Volts RMS line-to-neutral). Also, the high frequency ripple voltage must be less than 5.5 Volts RMS line-to-neutral at frequencies greater than 3 kHz. Note 2: The minimum typical power to the grid is 750 Watts when the Power Demand is 0 kW. For MultiPac, the typical minimum power to the grid is N*750 Watts. Note 3: Different models of MicroTurbines may be mixed within a MultiPac. The total available power is the summation of the powers available from the individual MicroTurbines. kW30HP = kW rating @ ambient conditions, of high pressure or liquid fuel Model 330 MicroTurbines kW30LP = kW rating @ ambient conditions, of low pressure Model 330 MicroTurbines N30HP = number of high pressure or liquid fuel Model 330 MicroTurbines N30LP = number of low pressure Model 330 MicroTurbines. 410000-001 Rev A (April 2002) Page 8 of 22 This information is proprietary to Capstone Turbine Corporation.
