| 摘要: |
| STATCOM控制器的详细模型在验证稳定性时存在很多困难。采用暂态稳定性模型（TS模型）来代替详细模型，并用改进Prony算法来提取电力系统的参数，避免了计算幅值和相位时精度不高的问题，克服了传统算法抗干扰较差的问题。在PSCAD/EMTDC中对详细模型和TS模型进行标准控制及辅助控制分析，仿真结果表明，提出的TS模型和改进的Prony算法能有效地解决控制器稳定性分析复杂的问题。 |

| Abstract: |
| Detailed model of STATCOM controller have many difficulties in stability validation. This paper adopts the transient stability (TS) model instead of the detailed model and uses improved Prony algorithm to extract the parameters of the power system. It avoids low accuracy of amplitude and phase calculated and overcomes the shortcoming in weak anti-interference ability of traditional algorithm. Standard control and supplementary control analysis of the detailed model and TS model is made in PSCAD/EMTDC. Simulation result show that TS model and the improved Prony method can solve the complex problem of controller stability analysis effectively. |
