摘　　要：针对用于AVR闭环测试的同步发电机组实时仿真提高仿真精度、改善仿真的实时性，通过严格的数学分析与仿真研究，证实了采用修改矩阵逆的方式代替LU分解求解离散化方程组时的有效性，进而提出了采用高阶发电机模型、计算速度快的解耦算法。按照发电机内在松散物理结构，采用将仿真计算分为2个部分，分别置于2片DSP芯片进行计算的并行处理技术。比较了解耦算法与原有算法的仿真结果。利用解耦算法和并行处理技术研制出了实时仿真实验装置，获得了较理想的仿真效果。The article aims at getting a better precision and real-time of simulation of synchronous generator for AVR closed-loop tests. Strict mathematlcs analysis and simulation prove that it is available for equation solution to replace LUdecomposition method with modifying invert of coefficient matrix. Based on them. a fast and precise decoupled arithmeticwith high-precision generator equation is provided. According to the incompact structure of generator. a novel parallel-process technology. which distributing simulation computation into dual DSP chips. is introduced. Comparison of decoupledarithmetic with existing arithmetic is presented. Based on decoupled arithrnetic and parallel-process technology. theequipment for real-time simulation test is developed and quite satisfactory simulation result is got.
