求翻译：利用连续性潮流，快速追踪到P-V曲线鞍结分岔点，并通过聚类分析法，将所追踪到的系统临界点归类为若干聚类中心，并以此张成若干切平面用以近似描述注入空间静态电压稳定域边界是什么意思？

Continuity of the trend to use, fast track to the PV curve saddle-node bifurcation point, and through cluster analysis, the system will be tracked to the critical point is classified as a number of cluster centers, and thus into a number of sheets to approximate the tangent plane describe the static

Using the continuous tidal current, traces the P-V curve saddle to tie the branch spot fast, and through the cluster analytic method, the system critical point classification which traces for certain cluster center, and becomes by this certain cuts the plane with to pour into the space quiescent vol

Use continuity trends, fast-track P-V curved saddle-node bifurcation points and clustering analysis method will be tracked by the system of classification of critical points as several cluster centers, and this description into tangent plane to approximate injection space of static voltage stability

Utilize continuity trend, fast to track form diverge order to P-V curvilinear saddle, and pass the analytic approach of the cluster, track systematic critical point that arrive classify several cluster centre as, so as piece become several cut level use describe static voltage of pouring into space
