9530679 Bose The periodic analysis of the security of a power system is done to ensure the ability of the power system to withstand contingencies. Such on-line analysis requires, in principle, the checking of the effects of hundreds of disturbances on the power system. The checking of the post-disturbance steady state of the power system for these contingencies requires only the handling of algebraic equations (albeit in large numbers and with nonlinearities), and such static security analysis (SSA) is now routinely done on-line. However, checking for instabilities during the disturbance itself requires the handling of nonlinear differential equations in addition to the algebraic equations, and the computation required for this dynamic security analysis (DSA) is about three magnitudes higher than that for the SSA. Thus, on-line DSA is still in its development stage although experimental prototypes have been implemented. This proposal is for examing the important aspects of this problem and developing new approaches for its solution. ***

9530679 Bose电力系统安全性的定期分析是为了确保电力系统抵御突发事件的能力。 这种在线分析原则上需要检查电力系统上数百种扰动的影响。 检查这些意外事件的电力系统的扰动后的稳态只需要处理代数方程（虽然在大量和非线性），这样的静态安全分析（SSA），现在例行做在线。 然而，在扰动本身的不稳定性检查需要处理的非线性微分方程，除了代数方程，这个动态安全分析（DSA）所需的计算约三个数量级高于SSA。 因此，在线DSA仍处于发展阶段，虽然实验原型已经实施。 这项建议是为了审查这一问题的重要方面，并为解决这一问题制定新的办法。 ***
