| 摘要: |
| 电力系统暂态稳定紧急控制问题是一类复杂的非线性动态优化问题，计算效率是其实用化瓶颈所在。利用差分化后紧急控制问题自由度很低的特点，应用简约空间内点算法进行求解。算法在C++ 环境下编程实现，对关键耗时部分多线程并行计算。算例测试结果表明，所提并行算法是有效的，且与传统内点算法相比，该算法消耗的计算时间和内存更少，能够求解大规模的电力系统紧急控制问题。 |

| Abstract: |
| Transient stability emergency control of power system is a complex nonlinear dynamic optimization problem and the calculation efficiency is the bottleneck of its practical application. As the freedom degree of emergency control problem after differencing is very low，the reduced-space interior point method is applied to solve the problem. The algorithm is written in C++ and the key time-consuming part is programed with multi-thread technique. Case tests show that，the proposed parallel algorithm is effective and it consumes less calculation time and memory than the traditional interior point method does，capable of solving the emergency control problem of large-scale power system. |
