| description | The invention discloses a 220kV voltage class unit wiring hydropower station self-energy-storage black-start system and method. The system comprises a hydro-generator, a high-voltage station transformer, a first 400V low-voltage station transformer, a second 400V low-voltage station transformer, a flood discharge door diesel generator, a main transformer and a 220kV line. The maximum allowable operation time of the speed regulator oil pressure system is determined through tests after power loss. When the hydropower station loses power, the governor oil pressure system is timely used for storing energy to open the guide vanes and adjust the water wheel to the rated rotating speed, the excitation system helps the generator to build voltage to the rated voltage in a direct-current excitationmode, and the auxiliary power system, the line charging test and the line power supply are further recovered. If the generator does not establish pressure successfully within the maximum allowable operation time of power loss |
