Compacting DC terminals
Designs for the compacting of urban power stations will help improve their appearance and lower construction and land costs. A joint effort of Electric Power Research Institute (EPRI), General Electric Co., and Consolidated Edison of New York will design a prototype compacted dc link to demonstrate the advantages of its low profile and the effective use of dc transmission to urban ac networks. The project will also test the concept of hvdc connector stations placed in basements. Slated for compacting are bus connections from transformers to valves and those from valves to the dc line. Liquid-cooled, gas-insulated, dead-tank valves will allow heat to be dissipated directly into the air and permit expensive bushings to be omitted. A separate project will be to compact filters. While some technology from ac applications can be used, additional information will be needed in such areas as the behavior of gases under dc stress. Thyristor valves, for example, will require major modifications. Project design plans and technical problems to be solved are described. (DCK)
