Abstract

The safe and reliable operation of power system has been severely threatened by frequent DC magnetic bias when the applied DC transmission system is operating in a single-polar ground loop mode or a bipolar asymmetric mode. Based on SQL SERVER 2012, this paper sets up an AC-grid DC network information database platform, which is aimed at DC bias problems. The paper also focuses on the respective development of simulation modules for ground, transmission lines, transformers, substations as well as the comprehensive one for DC current calculation in AC power grid. Then Visual Studio 2010 is applied to develop power system DC bias calculation software. The accuracy of AC-grid DC network simulation modules is finally proved by means of practical examples and comparison to other power system modulation software.
