摘　　要：重点分析"十二五"初期在我国华北、华中、华东地区形成特高压团状电网结构后,系统的稳定特性变化情况,与特高压试验示范工程投运初期的链状结构相比,在功角稳定、频率稳定、电压稳定、短路电流、运行灵活性等方面的改变情况和变化趋势,并对示范工程后续工程开展同步电网主网架发展敏感性分析,从提高系统安全性角度提出骨干网架规划发展建议。It is researched the changes of security and stability performance of ultra high-voltage （UHV） grid after mission-like power grids structure is formed in North, Central and East China areas at the beginning of the 12th Five-Year. Compared with the chain-like power grids structure when UHV test demonstration project put into operation, the changed and trends in the power angle stability, frequency stability, voltage stability, short-circuit current, the flexibility of operation, and so on is analyzed. Based on the sensitivity analysis on the UHV follow-up projects, it is put forward the development proposals of backbone network planning to improve system security.
