ADJUSTING CONVERTER CONTROLS FOR PARALLELED DC CONVERTERS USING A DIGITAL TRANSIENT SIMULATION PROGRAM

 ADJUSTING CONVERTER CONTROLS FOR PARALLELED DC CONVERTERS USING A DIGITAL TRANSIENT SIMULATION PROGRAM

A description of how accurate system modelling of a dc system

with an electromagnetic transient simulation program can be

used to study and correct interbipole oscillations between converters

connected into a parallel multiterminal system is given. The

paper shows how to decide on the detail of modelling that is

required, and demonstrates that it is often not enough to use

prepackaged , generic HVDC control models, supplied with these

programs. The detail of control models that are used in the electromagnetic

simulation programs are shown to have a significant

impact, in some cases, on the simulation results. In particular, a

case of six hertz oscillations, in the dc currents of two converters

on the Nelson River System, is accurately simulated, and it is

shown that control modifications suggested by the simulation

actually do eliminate the interbipole oscillations.
