The New Synthetic Loop Method of Ultra High Voltage Based on Simulation Research and Physical Experiment

In order to meet the requirements of operational test on extra high voltage DC transmission valve, we need to establish a special synthetic test system. This system is an enormous test system that consists of a voltage source and a current source, and its control system needs to satisfy not only the functional requirements but also safety demands. This system is extremely complicated. According to the relevant IEC standards, a type of ultra high voltage new synthetic loop scheme (NSLS) is proposed, where simulation research is made for the control section of the designed synthetic test system. Research results show that the method can provide important technical support for establishing synthetic test system.
