摘要(Abstract)：

发电机励磁调节器的精确建模是分析发电机无功支撑能力的基础。针对现有研究中缺乏考虑发电机励磁辅助控制功能对直流近区发电机动态无功支撑能力的影响这一不足之处,分析了发电机过励限制、低励限制、定子电流限制、最小励磁电流限制等励磁辅助控制功能对直流近区发电机无功特性、换流站母线电压的影响。实际特高压直流送端大电网仿真计算结果表明,发电机低励限制和最小励磁电流限制考虑与否会影响特高压直流送端暂态、稳态过电压水平,发电机过励限制、定子电流限制会影响特高压直流送端长期低电压的动态过程。发电机励磁辅助控制功能的考虑与否对于特高压直流送端近区电网的电压稳定、功角稳定分析结果有重要的影响。建议在特高压直流送端稳定分析中,发电机励磁模型采用包含各个辅助控制功能的详细励磁模型。
