90KVA(28.5VDC) towed AC/DC ground power vehicle

Beskrivelse:
The main configuration and performance of the towed AC/DC ground power vehicle engine: 1. Engine parameters a. Dongfeng CUMMINS QSB5.9, straight-line diesel six-cylinder, water-cooled, turbocharged, intercooled, electronic fuel injection, maximum power: 154KW/2200RPM, rotational speed: 1846RPM, emission standard: EU STAGE 3A; b. Protective devices: Equipped with emergency shutdown, overspeed shutdown, high-temperature protection shutdown, and low oil pressure protection shutdown devices. 2 The main performance of the towed AC/DC ground power vehicle generator A. Three-phase AC medium-frequency synchronous brushless generator (a well-known domestic brand); b. The rated speed of the generator is 1846 rpm, the rated power is ≥72kW, and the power factor is 0.8 3. Stability parameters of the output power supply of the towed AC/DC ground power vehicle 3.1 Voltage regulation capability: a. Voltage recovery time: 100 milliseconds to recover to rated voltage, +/- 1% b. Transient voltage regulation rate: +/- 13.8%, sudden increase from no-load to rated load c. Voltage modulation: No more than +/- 1%, from no-load to rated load d. Steady-state voltage modulation rate: 0.5% e. Voltage imbalance: When the three-phase load is balanced, it shall not exceed 1%. When 30% of the rated load is applied to any one of the phases, it shall not exceed 4% when the other two phases are unloaded. 3.2 Voltage Waveform: a. Peak coefficient: 1.414 +/- 0.07 b. Harmonic content: The total harmonic content shall not exceed 2%. Under a power factor of 0.8 and linear load conditions, the harmonic content of any phase shall not exceed 1.5% c. It has an automatic cable voltage drop compensation function, with the compensation value greater than 5% of the rated voltage. 3.3 Requirements for Frequency Regulation Capability: a. Frequency modulation: +/- 0.1%, from no-load to rated load to overload b. Overfrequency protection: 420Hz, 5 seconds, automatically cut off the power supply and connection with the aircraft system, and the overvoltage indicator light will be on. 3.4 Settings of the Power Output Protection System: The functions of the power output protection system: The power output protection system has the functions of delaying, cutting off output and resetting manually in case of abnormal conditions such as overvoltage, undervoltage, over-frequency, under-frequency and overload in the power supply system. b. The minimum time required for the protection device to cut off the output is less than 50ms. Jiangsu Tianyi Aviation Industry Co., Ltd.
