| Modern power system is a complex nonlinear dynamic system, stable operation, safety is the basic requirement of electric power system. In recent years, domestic and international had encountered several major cases of large area power outage. This attracted great attention from all walks of life on the power system security and issues related to reliability of power supply. The reserve power source automatic connection(RSAC) as an important device to ensure the continuous power supply of the electric power system, can effectively improve the reliability of power supply, ensuring continuous power users.In this paper, the study combined with the actual situation of Yangjiang power grid, study based on the reserve power source automatic connection strategy of Yangjiang power grid,mainly studies the following contents: 1. Analysis of a connection scheme, working principle and basic requirements of the reserve power source automatic connection; 2. Introduced the structure, operation and status of the reserve power source automatic connection of Yangjiang power grid, analysis the problems of the reserve power source automatic connection existing in Yangjiang power grid; 3. According to the actual situation of Yangjiang power grid,optimization the allocation strategy of the reserve power source automatic connection,puts forward some special strategy of the reserve power source automatic connection,include the reserve power source automatic connection matching between multilevel standby power supply,Through the tie line power supply higher substation. The formulation of the concrete implementation plan of the reserve power source automatic connection optimize strategies and organize the on-site implementation, acceptance and put into operation.Through the optimization of the reserve power source automatic connection strategy,Yangjiang power grid has obtained the splendid effect, greatly improving the safety and reliability of power supply. |
