摘要
广域测量系统(WAMS)应用同步相量测量技术,可对广域分布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契机。电力系统稳定分析软件中常采用静态负荷模型进行分析,研究表明,负荷模型参数对分析的结果影响很大。文章就广域测量系统在ZIP负荷模型参数辨识方面的应用进行了探讨,比较详细地阐述了辨识原理的内容及其在线应用的具体实现方法。在IEEE-30节点系统上的仿真结果表明验证了该辨识方法的可行性与有效性。
Wide- area measurement system using synchronized phasor measurement technology can be used to measure the electrical quantities in wide area distributed power ystem, and a new way is provided for the security analysis and stability control in large- scale power system. Most special software usually use static load model to analyze power system stabilization. Most studies indicate that the lead model parameters play an important place at the analysis result. Some important problems are studied in this thesis about the wide - area measurement system using in the parameter identification of ZIP lead model. ＇Ihen the contents of identification principle and the methods of on - line application are expatiated concretely. Simulation test with the IEEE - 30 bus system show the feasibility and availabihty of the identification methods.
