| Abstract: | 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. |
