Abstract

Transient Recovery Voltage (TRV) requirements for UHV and EHV circuit breakers were investigated with the simple radial and meshed network models by CIGRE WG A3.28 and it was confirmed that the CIGRE network models could provide the TRV behaviours effectively using the system and equipment parameters in a national project [1], [2], [3]. The method with the simple radial model was applied to evaluate TRV in 550 kV transmission systems in Thailand and the TRVs were compared with the results calculated in actual 550 kV transmission systems. Furthermore, the influences of various system and equipment parameters on TRV requirements for different fault interrupting conditions such as bus terminal fault (BTF), long-line fault (LLF) and transformer limited fault (TLF) were investigated in detailed. TRV evaluation with the CIGRE network models was also confirmed as an effective method to evaluate TRV requirements for different interruption conditions in Thailand.
