通过对法国超高压电力系统进行的案例研究，重新审视了决策树暂态稳定方法。简而言之，该方法包括建立离线决策树，能够随后评估系统的瞬态行为的precontingency参数（或“属性”），它可能会驱动的稳定现象。本案例研究的目的是调查实际可行性方面和特点的树木，在尽可能提高其可靠性，并在推广。可行性方面包括数据库生成，候选属性，稳定性类;树的功能，特别关注的复杂性方面的大小和解释能力，鲁棒性方面的建设和使用。通过定义和利用实用的质量措施来提高可靠性。一般化涉及多偶然性，而不是单偶然性树。结果表明，该方法具有真实的前景，能够满足电力企业的实际需要。>
The decision tree transient stability method is revisited via a case study carried out on the French EHV power system. In short, the method consists of building offline decision trees, able to subsequently assess the system transient behavior in terms of precontingency parameters (or "attributes") of it, likely to drive the stability phenomena. This case study aims at investigating practical feasibility aspects and features of the trees, at enhancing their reliability to the extent possible, and at generalizing them. Feasibility aspects encompass database generation, candidate attributes, stability classes; tree features concern in particular complexity in terms of their size and interpretability capabilities, robustness with respect to both their building and use. Reliability is enhanced by defining and exploiting pragmatic quality measures. Generalization concerns multicontingency, instead of single-contingency trees. The results obtained show real promise for the method to meet practical needs of electric power utilities. >
