Abstract

Due to the DC bias of the neutral earthed transformers caused by UHVDC earth-return current, it’s very important to study the DC current distribution in AC power grid. Based on the 800kV Xiangjiaba-Shanghai UHVDC power transmission project, this paper simulates the DC current distribution in Northern Zhejiang AC grid by establishing a complete model based on the actual power grid and soil data in CDEGS. By the comparison of the simulation values and measured values, the validity of the model is verified. At last, a proposal is put forward to restrain DC current distribution in Northern Zhejiang AC grid.
