Thyristor Voltage Regulator For Dispersed Power Sources And Its Test Results

摘要

This paper presents thyristor type voltage regulator (TVR)[1] developed by TOSHIBA and KITASHIBA ELECTRIC, its developmental background, equipment configuration, features, functional comparison with Step voltage regulator (SVR), verification test and review of the result. TVR comparison with SVR, the response is better, was able to achieve the maintenance free of the tap changing. TVR also has jumping-tap control. In order to verify the features of TVR and detailed tap changing, TVR were interconnected to distribution line of Kitashiba plant, and field tests are conducted. Tap changing performance and High speed response for frequent voltage fluctuation were verified by the verification test.
