In addition, the high savings rate in most of the region, fuelled by a decade of export-led growth, provided governments with ample firepower as the crisis developed for massive stimulus programmes, estimated by Mr Redward at 3.2 per cent of regional GDP.

此外，在为期10年的出口主导型增长推动下，亚洲多数国家的储蓄率较高，这在危机发展期间为政府提供了充足的火力，让它们出台大规模刺激计划。据瑞德华估算，这些刺激计划的规模占亚洲GDP的3.2%。

After flow and transient stability calculating of the 330kV grid, we got the over-load and hazard lines set. Then we gained the redundant network needed to be built according to the increasing power supply and load in 2010. Adopting regradation step-by-step algorithm by which we can improve the calculation efficiency , we compared the validity of every line, deleted lines with low validity until no redundant line is in the network. At last we got the target network framework adopting the improved ant colony algorithm. Flow distribution, construction investment assessment and target framework of Gansu long-term planning all be considered, from the viewpoint of to be economic and reliability the feasibility of the improved ant colony algorithm is discussed.

在对2006年该网架结构进行了潮流计算与暂态稳定计算分析后，得出了系统的过负荷与危险线路集，并针对2010年新增的电源和负荷点确定了冗余的待建网架，然后利用逐步倒推法比较各待选线路在系统中的有效性，逐步去除有效性低的线路，直到网络中没有冗余线路为止，以此来以提高优化算法的计算效率，最后利用改进后的蚁群算法确定优化后的目标网架结构，并从潮流分布、建设投资估算等方面与甘肃电网远期规划中确定的目标网架进行了比较，从可靠性和经济性角度论证了改进蚁群算法在网架优化中的可行性。
