电力系统暂态稳定分析的能量函数法

介绍暂态能量函数法（ＴＥＦ）的一种新型解算方法，其运算速度、数值鲁棒性、适用问题大小及模型多样性方面可以满足生产实际的需要。这种方法具有以下两个主要特点：使用网络结构保持模型，充分利用稀疏矩阵法。其基础是主导不稳定平衡点的求解、自动变阶变步长积分法及主导不稳定平衡点的新求法。用本方法编制的程序通过ＥＰＲＩ６机试验系统的求解得到了满意的结果。

The Transient Energy Function Applying to Electric Power System Transient Stability Analysis

This paper presents a new transient energy function(TEF) solution algorithm that fulfills production requirements.It is relatively fast,robust,unrestricted in problem size and ,in principle,permits use of any models justified by TEF theory.Its major features are preservation of network structure,sparse matrix methods.TEF analysis based on the controlling unstable equilibrium point(CUEP),automatic variable step/order in integration and a new CUEP solution.The software programmed by the author according to the method has been tested on the EPRI 6 machines test system and gained satisfied results.
