摘要
为了对大规模电力系统进行分析计算,本文对几种大系统状态矩阵降阶的方法进行了研究与比较,考虑对系统所关心的不同固定模式进行分层降阶.在一16位机系统上进行试算,对不同模式和不同降阶方法的结果进行了分析比较.
The dimension of power system is higher and higher because of the enlarging of system scale and the introducing of complex control systems, and then the ＇dimensionality＇ trouble may happen, which makes QR method not satisfy requirement. For the analysis and computation of the large power system, several order reduction approaches are described in this paper, different order reduction schemes for different concerned modes are considered. They are tested on a 16-machine system, and the results are compared and analyzed.
