The paper introduces the problem of "start blackscreen"as to all kinds of breakdowns when computer sets up,analysis all sorts of phenomenons when computer sets up and gives appgopriate process methods.

This article describes how to realize black start scheme of Hunanzhen Hydropower Station, which is the black start source of the Wuxijiang power grid zone of Zhejiang.

The selection of source and path as well as its calculation are discussed for Tianjin power grid black startup.

If there is only one external power supply in the auxiliary power system,the emergency power supply system should make the power plant have the ability of black startup ,so that when auxiliary power supply disappears,the emergency power supply units can start up to resume power supply.

An approach based on superposition is used to decompose sudden three-phase symmetrical load resumption in black startup into two simpler independent problems.
