摘要
以海洋石油平台微电网为背景,采用PSCAD仿真软件搭建变压器仿真模型,对变压器产生的励磁涌流及和应涌流进行仿真,调整变压器接地方式、接线组别、合闸角度、剩磁以及系统阻抗观察并记录励磁涌流的变化情况,调整2台变压器接线组别、接地方式,观察和应涌流的变化,得到变压器不同条件下空载合闸的量化结果,提出规避变压器空投风险的相应措施。
The simulation model of transformer was established by PSCAD for the offshore oil platform micro grid,to analyze the inrush current of transformer under different condition. By adjusting grounding mode,wiring group,closing angle,remanence and system impedance of the transformer,the changes inrush current and surge inrush was observed and recorded. The quantification of no-load of transformer under different conditions was given,and the corresponding measures of no-load transformer risk aversion was put forward,providing a reliable means of operation for oil platform for the safe operation of power grid.
