摘　　要：结合时域仿真 ,提出了多机系统中单机加速面积 ,减速面积计算方法 ,稳定判据 ,稳定裕度 ,不稳定裕度。与传统的时域方法相比 ,本文方法能减少计算时间 ,给出丰富的系统稳定信息 ,本文所提稳定判据与时域仿真所得临界切除时间完全一致。提出了加速面积、减速面积以及减速功率的灵敏度分析方法 ,能用于经济运行中系统稳定裕度约束和在线稳定监示。Based on the time domain simulation, the calculation method for single machine acceleration area and deceleration area, stable margin and unstable margin, critical machine equal area criterion (SMEAC) are proposed. The modeling method for load in classical stability analysis is proposed. The analytical sensitivity is derived. Compared with the traditional time domain simulation, the method can reduce calculation time, provide more stability information. The critical clearing times obtained by using both TDS and SMEAC are identical. Practical system analysis is presented.
