| 摘 要： | 为了研究响水涧抽水蓄能电机发电工况下承受电力系统扰动的能力,本文基于单元电机建立了抽水蓄能电机的场路耦合时步有限元模型。采用该模型计算了系统发生三相突然短路后的大扰动过程,并分析了抽水蓄能电机运行在发电工况下的暂态稳定性。在此基础上,对比研究了时步有限元模型和传统Park方程所计算结果之间的差异。研究结果为指导抽水蓄能电机的实际运行提供了理论依据。

Study on the Transient Stability of the Pumped Storage Machine Under Generator Operation Mode |
| |
| Abstract: | In order to study the capacity of Xiangshuijian pumped storage machine under disturbance of power system, the field-circuit coupled Time-Stepping Finite Element Model (T-S FEM) which is based on unit machine is established in this paper. We calculate the large disturbance process after three phase sudden short circuit and analysis the transient stability of the pumped storage machine under the condition of generator operation. On the basis, we compare and research the difference of results calculated by T-S FEM and Park equation. The results provide the theoretical foundation for guiding actual operation of pumped storage machine. |
