Abstract:
A new method for the analysis of ac voltage stability problems at HVDC terminals, when imbeded in large networks, is presented. The method can be used to evaluate the effects of dc modes of operation, ac system operating conditions and VAr compensation schemes on the combined system voltage stability. Dynamic properties of both ac and HVDC systems are incorporated in the solution algorithm. A step-by-step technique is developed for integrating the new algorithm with available load flow programs. Examples are given to demonstrate the performance of a new control strategy for HVDC converters connected to weak ac systems and the results are compared to classical solutions.

Summary
The Blackwater HVDC station connects the two asynchronously operated ac systems of Public Service Company of New Mexico (PNM) and Southwestern Public Service (SPS). It allows for bidirectional power transfer between the Western and the Midwestern power grids of the USA.
The nominal power is 200 MW, continuous overload is 220 MW at maximum ambient conditions using redundant equipment. Main reason for the installation of the Blackwater station was to minimize costs for electrical energy generation.
A remarkable feature is the station's reactive power capability. The station controls, besides the active power, ac voltage and adjusts itself to the optimum operating point.
The station was designed, built, commissioned and released for commercial operation within less than two years work lasting from Feb. 83 to Dec. 31, 84.
