| 摘 要： | 针对河南电网在特定扰动下所产生的功率振荡问题,采用傅里叶变换、小波变换和Prony算法分析了河南电网广域测量系统提供的扰动数据,计算了振荡参数。分析过程和结果显示,各种方法对信号的处理能力和所提供的信息各不相同。在不同的扰动下河南电网均具有较强的阻尼,但被激发的动态特性存在差异。研究分析表明,采用适当的方法,基于WAMS系统的电网动态特性监测和分析可为区分不同的扰动和处理振荡提供丰富的信息。

| Abstract: | Wide-area measurement system(WAMS)provides novel method to power system dynamic performance analysis,avoiding the difficulties in modeling and getting parameters.In view of the problem of power oscillation under special disturbance of Henan power grid,disturbance data provided by WAMS of Henan power grid are analyzed by Fourier transform,wavelet transform and Prony algorithm and oscillation parameters are calculated.The analysis process and results show that methods above-metioned have different treatment capacity to signals and information provided.Henan power grid has strong damping but shows different dynamic performances.It can be concluded that by using proper methods,monitoring and analysis based on WAMS can provide rich information for disturbance distinguishing and oscillation treatment. |
