摘　　要：较为全面地综述了国内外关于电力系统暂态稳定预防控制的研究状况。首先通过对预防控制数学模型的分析,给出了预防控制算法在数学表达上的控制过程,并将预防控制算法分为三类,对约束转化技术,最优控制理论,灵敏度技术,单机无穷等效,非线性规划,智能优化等技术在预防控制中的应用做了一定的归纳,对不同算法在常用算例的优化结果做了总结比较。在评述各种算法基础上,对一些算法中存在的问题如初值变分、准确性、迭代次数等进行讨论,并指出了改进预防控制算法的研究方向。This paper provides an overview of the algorithm for preventive control of transient stability in power systems. According to the analysis of the mathematical model, the process of the preventive control is presented. Besides, the methods are classified into three categories and various techniques including function transcription, optimal control theory, trajectory sensitivity, the One-Machine Infinite Bus Equivalence （OMIB）, nonlinear programming and the computational intelligence optimization for the preventive control in power systems are summarized and evaluated. The simulation results on some common testing systems by the classic methods are shown for more distinct illustration. Finally, on the comments and discussions of the present methods, some existing problems such as variation of the initial value, the accuracy and the iterations in some algorithms are given, and the main development trend is pointed out for improving the preventive control in power system.
