As a new generation of DC transmission based on voltage source converter(VSC)
self-turn-off devices and pulse width modulation(PWM) technology
the flexible DC transmission(VSC-HVDC) has a higher requirement for the transient response time and protection characteristics of DC measuring device. Aiming at the VSC-HVDC DC voltage measuring device
the research that involves the step response test technology of rise time
delay time and other protection properties and characteristics is carried on. The transient response test system of DC voltage measuring device is developed to meet the standard requirements of transient response test and measurement with the rapid rise and long pulse test voltage source
that is based on the solid MARX principle. The simulation and experiment results show that the performance indexes meet the requirements of DC voltage measuring device transient response. The proposed VSC-HVDC DC voltage measuring device protection test method and equipment are convenient and effective to evaluate the transient response characteristics of DC voltage measuring device and ensure the safe and stable operation of HVDC transmission system.
