为追求更高的传输效率及传输容量,特高压直流输电工程在我国电网中的应用越来越广泛。晶闸管阀作为其中的关键设备之一,必须通过完备有效的型式试验,以确保阀的设计是正确的。在IEC 60700-1标准的基础上,通过对现有运行试验电路的深入调研,开发了一套新的运行试验装置,并将其应用到宁东—山东±660 kV直流输电工程,试验结果表明该工程晶闸管阀的研发是成功的。
In pursuit of higher transmission efficiency and transmission capacity, the application of UHV DC transmission project in China’s power grid is more and more widely used. Thyristor valve as one of the key equipment must pass a complete and effective type test to ensure that the valve design is correct. Based on the IEC 60700-1 standard, a new set of operation test equipment was developed through in-depth investigation of the existing operation test circuit and applied to ± 660 kV DC transmission project in Ningdong-Shandong Province. The test results show that The project thyristor valve research and development is successful.
