摘要
电力系统低频振荡问题十分复杂 ,现有的研究方法多侧重于理论分析 ,与现场实测数据结合不够 ,因此难以得到令人信服的结论。文中提出了一种低频振荡研究的试验方法 ,该方法采用Prony算法对现场实测数据进行全面分析 ,并用实测数据分析结果与理论分析结果进行比较。采用该方法对河北安保线振荡进行了实例分析 ,结果表明所提出的试验方法是一种分析低频振荡问题的有效方法。
The problems of low frequency oscillation in power systems are very complex. Most of the existing research methods emphasize particularly on the theory analysis and ignore the measurement of field data. Thus, believable conclusions are difficult to obtain. A set of experimental method is therefore introduced, based on the Prony algorithm, to analyze field data in an all round and the results are compared with those of the theory analysis. In the end of this paper, the validity of the experimental method is verified through in the An-Bao line oscillation case of Hebei Province.
