Reporters from the national grid heilongjiang Harbin ultrahigh pressure companies know that China's first multinational dc networking engineering 500 kv dc converter back-to-back networking between China and Russia heihe project, recently successfully complete system commissioning work, on 1 January into trial operation.glue stick The project begin formally put into production, the Russian far east to heilongjiang electric transmission grid power grid will, about 4.3 billion kilowatt-hours in power supply.
500 kv dc converter back-to-back networking between China and Russia heihe project is the national grid company first overseas cooperation projects, is currently planning and construction of China's overseas purchase of electricity from the highest voltage level, the largest capacity transformation project. This project was on July 12, 2007, glue gun formally began construction, by November 2011, the project has completed rheological change and change flow valve installation ontology installation, the joint scheduling operation, between China and Russia, and through the heilongjiang electric power station of the qualitative inspect the qualitative inspect acceptance.
December 31,, Russia and China dc networking heihe back-to-back dc system engineering commissioning work finally started. On that day in the big heat load operation test, the power converter by the load to 750 mw full load operation step by step. After more than six hours of commissioning test, dc system all normal.
According to information, Russia and China international power transmission project after the completion of the test run back-to-back, will begin formally put into production, the Russian far east to heilongjiang electric transmission grid power grid will, about 4.3 billion kilowatt-hours in power supply.
The personage inside course of study thinks, the completion of project put into operation to improve energy efficiency and the far east, expand between China and Russia energy project cooperation and promote China's northeast power network is built, strengthen economic development between the two countries and complementary advantages to have the important meaning.
