英文摘要： With the dimension of the structure increasing and the uncertainty of the system operating more complicated, the local fault of power grid spreads faster, which leads to the collapse of the entire power grid. To deal with this problem, recovery strategy for complex grid based on the synchronous adaptive control and the dynamic analyses of the wide-area data detection of power and electric power grid controllable node is proposed. The strategy solves a series of difficulties, such as power system dynamic fault early warning and inaccuracy. The notable feature of this study is as follows: 1) Realize the power grid dynamic faultearly warning and fault diagnosis with the wide-area data testing technology. 2) The electric power grid node modeling theory of fuzzy fractional order is raised, solving the problem of smart power network node observation and the network structure topology identification research. 3) Synchronous adaptive control method of electric power grid controllable node is presented, realizing the power system recovery after an urgent power grid fault. The product of the research will realize the fault predictive and fault diagnosis of procedure object under the circumstance of complex industrial field conveniently and provide the necessary basic theory and critical technology guarantee to support t
