| 摘要: |
| 在讨论统一潮流控制器UPFC(Unified Power Flow Controller)的模型和合UPFC的暂态稳定算法实现基础上，重点研究了UPFC在随机故障和三种不同控制策略下对系统概率暂态稳定性的影响。概率暂态稳定性计算采用非序贯蒙特卡罗仿真，并给出了修正EPRI—36系统的结果，指出了在UPFC同一控制策略和初始条件下可能产生正面和负面作用。分析表明：选取合适的控制策略和调节参数，选择最佳安装地点及投／切时间对系统暂态稳定性的改善有积极的意义。 |

| Abstract: |
| Based on the discussion of the UPFC(Unified Power Flow Controller)model and the al-gorithm of transient stability of system with UPFC,the effect of UPFC on transient stability of power system under the random faults and three different control strategies is emphasized.App-lying the non-sequential Monte-Carlo simulation,the results of probabilistic stability calculation for the modified EPRI-36bus system are given.It is pointed that both positive and negative effects are possible under same UPFC control strategy and same initial conditions.The selection of the suitable control strategy and parameters and the best installation place and switching time is very important for the improvement of system transient stability.This project is jointly supported by National Natural Science Foundation of China(59977004),Natural Science Foundation of Anhui Province(00104421),and Doctor Center Foundation of Edu-cation Ministry. |
