Beautiful boat hill archipelago is having the calling card of the whole nation of much Zhang Xiangyu such as travel, fishery, especially the calling card of ” of transmission network of the first dc of whole nation of that piece of “ , more cover is sufficient precious.

On December 8, 1987, mainland of cross the East China Sea, join and boat hill investment of transmission network of ——100 kilovolt dc tries the electric power main artery of this island move, the project of dc transmission network that proper motion of this our country designs production installation, big 碶 presses down Xi Qining wave, northeast comes riverside of head of a huge legendary turtle that decide the of great capacity, the project includes trolly wire of dc of rectification station, inversion station, 42.1 kilometers road and cable of 12 kilometers sea floor, it is ministry of state committee of science and technology, water and electricity and machinery appoint national emphasis science and technology of the organization tackles key problem project.

Li Wenwei is the main participator of project, he says, area of country of 80 time boat is only the installed capacity of 12 thousand kilowatt, a lot of islands still are supplied without electric power, to satisfied the requirement using phone of 8889 people, promoted local economy to develop quickly, zhou Shan strove for transmit electricity of first dc of countrywide this project.

And choice dc transmit electricity, it is to think the first “ eats crab ” not only, more important is a lot of advantage that saw it: Carry a capacity big, the volume that carries power and direction can be controlled quickly and adjust; Loss of circuit have rendered great service is small, do not suffer a system to stabilize ultimate limitation; When dc allow working report pressure ratio to be made an appointment with below communication 3 times taller, appropriate Yu Hai issues transmit electricity; Do not accept the restriction that transmit electricity is apart from, did not communicate the worry of electric current of the capacitance in cable road, without magnetic induction loss and dielectric loss, isolation voltage is relatively inferior wait.

At the beginning of 1984, the project stars building formally, home does not have the precedent of dc transmit electricity at that time, lack data of foreign advanced technique again, project technology personnel has the collect in a bit data from all sorts of magazines, study only, fumble, go to Wuhan again manufacturer of high-pressured laboratory, cable the local go on a pilgrimage for Buddhist scriptures such as the home, the production the programme of construction that item-by-item decided capacitor of hall of a powerful person, high pressure to wait. Among them, be made to succeed and lay submarine cable, they undertook oceanographic research and survey 7 times early or late, still laid cable of a marine experiment.
