520    This research details the development of a small signal 
       model of an high voltage DC (HVDC) terminal and analysis 
       of the HVDC terminal interactions by using small signal 
       techniques. The modeling requirements to adequately 
       represent the dynamics of the HVDC converters and AC 
       networks are investigated. The derived small signal model 
       of the HVDC system is validated against time domain 
       simulations by using an electromagnetic transient 
       simulation program PSCAD/EMTDC and frequency domain 
       analysis by using eigenvalues, eigenvectors, and 
       participation factors. The adequacy of the derived small 
       signal HVDC model with PSCAD/EMTDC model was also analyzed
       by using Eigenvalues analysis and Prony analysis 
       techniques. The time domain and frequency domain analysis 
       show that the derived small signal HVDC model with 
       constant admittance AC network gives good results at low 
       frequencies (0--2 Hz) and above this frequency range the 
       results are not meaningful. Based on the research results 
       it is recommended that the derived small signal HVDC model
       must be modeled with the dynamics of the AC network to 
       obtain meaningful results
