Suining, Sichuan, China December 16, at 11:55 on December 15, with the 110 kV substation Eucalyptus No. 2 main transformer substation trip loss of power, 3, the main transformer transformer automatic investment from the successful investment. In just a few seconds, the station ebony substation to restore the normal power supply, marking the transformer from the new technology for the first time in the State Power Suining power supply company to achieve.
For a long time, due to the power industry is highly concerned about the reliability of power grid operation, so at all levels of power grids, the more widely used is into the line and subparagraph from the cast. 110 kV ebony station is 2016 infrastructure projects, the initial design is the station does not have the function of the transformer from the cast, in order to meet the requirements of the economic operation of the power grid to improve power supply reliability, Suining relay protection professional broadening ideas, decided to Ebony station infrastructure projects for the first time a bold attempt to achieve the station between the two light load between the main transformer from each other quickly. The company relay protection professional access to a large number of information through the site, many times to the infrastructure site and the device manufacturers, design units, installation and commissioning units to communicate, comprehensive analysis and evaluation of the transformer to vote in the action logic may exist to protect against atresia and overcome difficulties, Take a variety of measures, and ultimately these problems can be one by one solution.
The application of new technology of transformer automatic backup in Ebony substation can effectively reduce the loss of double main transformer in low load level of transformer substation, and improve the operation efficiency of the equipment under the premise of effectively guaranteeing the reliability of power supply. Preliminary estimates, the ebony station transformer through a primary and a standby operation, can save about 300,000 kWh of active power. The company will continue to sum up experience, combined with the actual power grid and equipment, so that the transformer equipment from the new technology in the Suining gradually promote the use of the grid.
