| 摘 要： | 广域测量系统(WAMS)可对广域分布的电力系统的电气量进行实时测量,为大型电力系统的安全分析和稳定控制提供了新的技术途径。提出了应用WAMS信息进行动态等值的思想。具体研究了一个发电厂的动态等值,并应用非线性最小二乘法来辨识等值模型的参数。最后应用某一省级电网的系统模型进行了动态等值数字仿真研究,结果表明该方法具有很好的准确性和可信度。 |

| Abstract: | Wide Area Measurement System(WAMS) can be used to measure the electrical quantities in wide area power system,so it provides a new technical path for the security analysis and stability control in large-scale power system.In this paper we studied dynamic equivalence method based on WAMS information,concretely researched the dynamic equivalence model of a power plant and applied nonlinear least square method to identify the parameters of the equivalent model.In the end we did dynamic equivalence digital simulation experiment by an interprovincial power system model.The results indicate that the method of this paper has a well precision and feasibility. |
| Keywords: | wide area measurement system dynamic equivalence parameter identification least square method |
