| 摘要: |
| 用于电力系统暂态稳定研究的励磁系统传递函数模型简化了功率单元和励磁电源，无法满足准确分析暂态稳定问题和励磁装置特性的需求。考虑功率单元和励磁电源以及励磁装置灭磁特性，提出更为完善的自并励静止励磁系统精细模型，在PSCAD／EMTDC中建立电磁暂态仿真模型，分析机端故障对电力系统暂态稳定以及励磁装置特性的影响。仿真结果表明，在发生近机端较严重的接地故障时，采用自并励静止励磁系统精细模型对电力系统暂态稳定以及励磁装置特性进行分析是十分必要的。 |

| Abstract: |
| Since the power unit and exciting power source of transfer function model for excitation system are currently simplified in the transient stability study of power system，the requirements for the precise analysis of transient stability and excitation characteristics could not been satisfied. A more perfect model of bus-fed static excitation system considering the power unit，exciting power source and field suppression characteristics is proposed. An electromagnetic transient simulation model is established in PSCAD／EMTDC to analyze the impact of generator terminal fault on the transient stability of power system and the characteristics of excitation device. Simulative results show that，it is necessary to apply the proposed model for analyzing the transient stability of power system and the characteristics of excitation device during the serious grounding fault near generator terminals. |
