| Abstract: | Converter valve is the core equipment of the converter station. To ensure the safety and stability of the HVDC and achieving rectifying and contravariant function, it is important to obtain control and protection system of converter valve. This paper presents the various protection technology of converter valve, which includes voltage sharing buffer protection circuit of internal converter valve, positive over voltage protection, reverse over voltage protection, electric protection and external protection. Therefore, it has reference value for design of converter valve protection, operation and maintenance. |
