Abstract

The optical current transformer play an important role on the security and stability of the power system especially HVDC. The HVDC control and protection system cannot be field verified without field simulation for the optical current transformer secondary signal. But the existing method for field simulation of optical current transformer is lacking for easy to implement and meeting requirement. This paper proposed a novel method for field secondary signal simulation of optical current transformer. The advantage of the method are that not need to explain the photoelectric conversion protocol, easy to implement and meeting requirement, low security risk, and low cost. The field test device has been developed with secondary signal simulation quantity of optical current transformer. Its validity was verified by field testing of secondary signal simulation of optical current transformer in echeng convert station of jiang-cheng ±500kV HVDC transmission project.
