Influence of Different Simulation Models for Electrical Characteristic Analysis of the Arrester of AC Filter
AC filter is an important equipment in DC transmission system. This paper mainly analyzes the influence of simulation model on the electrical characteristics (overvoltage
current and absorbed energy) of the arresters for AC filter
and carries out the modeling and simulation calculation for the filter input and AC filter bus grounding fault based on PSCAD electromagnetic simulation program. The simulation result shows that when the AC filter is put into operation and the traditional large group model for a single filter (model 1) was used for simulation
the arresters of the working filters did not act
which is different from the actual situation; under the filter input and filter bus grounding fault
the overvoltage of the arrester of each group of filters in complete parameter model (model 3) was lowered by 21% compared to that in the original system model (model 2) and model 1
and the current was reduced by up to 53%
but the absorbed energy increased by up to 56%. Therefore
if the complete parameter model is not used in the insulation design
the voltage and current design value of the arrester could be too large while the energy design value could be too small. At the same time
the action of the arresters of other AC filters in the same group could be easily ignored when the filter is put into operation.
