高压直流输电换流阀TCU单元故障测试方法研究

在科技的牵引下,高压直流输电换流阀应用领域逐渐广泛,高压直流输电换流阀的使用,大大提升安全性。但是关于其TCU单元的检测技术尚不成熟,针对TCU控制单元较为完整、有效的测试系统还不具备,在这样的前提下,设计并实现较为完整的换流阀性能检测和核心单元的测试,具有重大研究意义。在实际工作中,将科学TCU测试方法高质量、巧妙融合到检测TCU故障方式中,可以精准实现测试数据分析,成功定位故障部件,体现测试方法设计合理的同时,也满足工程应用需求,对今后的高压直流输电工程的优化投建和长效运行意义较大。

Under the traction of science and technology,the application field of HVDC converter valve is gradually extensive,and the use of HVDC converter valve greatly improves the safety.However,the testing technology of its TCU unit is not yet mature,and a relatively complete and effective test system for TCU control unit is not yet available.Under this premise,it is of great research significance to design and implement a more complete converter valve performance test and core unit test.In practical work,the high-quality and ingenious integration of scientific TCU testing methods into the TCU fault detection mode can accurately realize the test data analysis and successfully locate the fault components,which not only reflects the reasonable design of the test method,but also meets the needs of engineering applications,which is of great significance to the optimization and long-term operation of HVDC projects in the future.
