摘要
设计了高压直流输电动态模拟系统,该模拟系统的目的是为了校验应用于工程的直流控制保护系统,并进行理论研究。根据模拟总体设计原则,对主接线、换流变、换流阀、直流场、交直流滤波器、线路-大地回路进行了模拟。模拟系统不仅能模拟正常运行的各种工况,还可以模拟交直流滤波器内部故障、输电线路故障、换流阀故障、换流变压器等各种故障情况,直观地反映了这些设备上的各种电压、电流量,包括它们的谐波和暂态过程,对控制保护的测试达到了预期的效果。
A dynamic simulation system of the HVDC system is designed and constructed in order to test control and protection subsystems in the HVDC project. According to the overall design principle of the dynamic simulation system, the main AC circuit connection, transformer, converter valve, DC magnetic field, AC-DC filter and line-earth circuit etc are modeled. Normal and all kinds of fault conditions including interior faults in AC-DC filters, faults in transformers, faults on transmission lines and faults in converters can be simulated in which the voltage, current, harmonic and transient process of these devices can be obtained and expected results have been achieved on the test of the protection subsystem.
