The Establishment Of Black Start Scheme For Dongguan Electric Power Network And Research On Support System Of Communication Power Supply

As a power system after a serious accident the necessary security measures, black-start programs are beneficial to shorten the outage time, reduce the loss of equipment and user outage. Dongguan, Guangdong Province power grid network, as a regional power grid, it is necessary under the regional power grid and local power plant operating characteristics, with the main network for black-start program of research and experimental work. Authors participated in the Dongguan grid black-start program development and research work, in the study design process, the systematic study of the power grid black start and system restoration of the relevant knowledge, systematic analysis of the Dongguan area power grid in the black start capability and initial zoning process, developed a black-start the implementation of the program, focusing on the practical combination of Dongguan grid black start generators on the issue of self-excitation of the analysis and research, so as to Dongguan power to start the implementation in black to provide a theoretical basis. At last, the real article, Dongguan grid black start in the communication power of the security system conducted a focused analysis and research.
