Trolleybus Propulsion Evaluation

摘要

The report documents the findings of a test program conducted on San Francisco Municipal Railway's trolleybus system to evaluate four different types of propulsion systems. Equipment tested in this program was the General Electric switched resistor controller, an air-cooled thyristor chopper made by Westinghouse Electric Corporation, a freon-cooled thyrister chopper made by Alsthom Atlantic, and an AC propulsion system made by Garrett-Stromberg. The report includes a description of each propulsion package supported by schematics and photographs. The data recording equipment (BUSDAC) and the data analysis equipment (PLOTPAC) are described in great detail. The report also includes the test routes, bus loading information, and test schedules. The findings are documented in terms of comparisons of each system's efficiency and ability to regenerate, and a cost analysis comparing switched resistor and advanced propulsion is also presented.
