摘要
Time domain digital simulation of HVdc transmission enables harmonic stability of a system to be studied. Two alternative measures of controlling harmonic instability were investigated; the use of C-type ac filters and a simple addition of a harmonic damping circuit in the rectifier converter control. The design of a C-type filter is described and its effectiveness presented. Harmonic damping by controls consists of taking the output from a fast response dc current transducer, passing it through a filter and a gain and adding the output to the firing angle order. Both methods result in stable recovery from faults at both rectifier and inverter terminal busbars for a dc system inherently harmonically unstable. © 1990 IEEE
