This paper surveys the important dynamic performance parameters of two-terminal HVdc systems. Specific HVdc systems included are the Pacific HVdc Intertie, the Nelson River Bipoles 1 and 2, the Eel River and Stegall back-to-back ties, the CPA-UPA (CU) and the Square Butte HVdc systems and the Vancouver Island cable system. The parameters tabulated (Table 1) and the dynamic performance features described should be sufficient for dynamic performance evaluations of the corresponding ac/dc systems by means of generally available transient and dynamic stability programs. These characteristics of existing HVdc systems may influence the modeling and design of future HVdc systems for transmission planning studies.
