| Abstract: | The small hydropower is a kind of clean energy.When small hydropower access to the grid,power distribution network become a multiple power supply system.It will cause some of the effects of the distribution network about power quality,relay protection and safely power supply.From the aspects of power system,power transmission system,power system reliability,power quality,loss of power network,reactive voltage,grid transformer,grid scheduling,real time monitoring and relay protection of system,the reasons about small hydropower access to the grid are analyzed,and measures to solve the problems are also presented. |
