| 摘要:针对气体发动机负荷突变时瞬态响应性差的问题，以某大功率涡轮增压天然气发动机为例，采用理论分析、仿真计算与试验验证相结合的方式，分析响应滞后的原因，并提出了更换更小截面的涡轮增压器喷嘴环，调整点火提前角以及设置燃气喷射量限制等改进措施。经试验验证，改进后的发动机在负荷突变情况下满足G2级别的发电机组性能要求。 |

| Abstract:To deal with bad transient response of gas engines in the condition of sudden load changing, research was carried out on a high-power turbocharged natural gas engine. Through the combination of theoretical analysis, simulation calculation and experimental verification, the reason of late response was analyzed, and the improvement measures were proposed, including replacing the turbocharger injector ring with smaller cross section, adjusting ignition advance angle, and set the limitation of gas injection volume. Tests verified that the improved engine could meet with the performance requirements of class G2 gensets under the condition of sudden load changing. |
