Embodiment Construction
[0027] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0028] The series transformer is charged from the low-voltage side and the high-voltage side of the series transformer respectively, and the temporary protection during the charging process is configured.
[0029] First, the low voltage side of the series transformer charges
[0030] For the actual UPFC project, in order to give full play to the control performance of the converter valve, a knife switch is configured in the AC switch yard on the valve side so that it has a flexible operation control method. A typical configuration method is: For UPFC projects, generally It also has the function of static synchronous series compensator (SSSC) operation. When a converter in the UPFC system fails, the remaining intact converters can be connected in s...
