| Abstract: | DC system protection is important in HVDC control and protection system. The design of DC protection shall ensure that DC transmission system operates safely. In this paper, both system configuration and operation mode are analyzed for Lingbao converter station, a back to back HVDC link between Northwest to Central China. All kinds of faults and abnormal status are taken into consideration. DC system protection is designed and configured according to the principle and requirements of the Technical Specification. The scheme has been tested in Electro Magnetic Transient Digital Simulation for power system. The complete control and protection system of the project is in the process of the last simulation test. |
