Analysis of Automatic and Fast Switching Scheme for Closed Loop Point of the Power Grid in the Baotou Area

Abstract

The influence of the access of different power source unloop points on the power grid is summarized. Transient simulation analysis is carried out on voltage fluctuation, power flow fluctuation, short-circuit current, and voltage unbalance degree after the power grid is closed. The feasibility of the fast-switching device configured on the distribution network side is demonstrated, and the possible problems of the fast-switching device in the operation process and their influence on the power grid are analyzed. Ultimately, it lays a theoretical foundation for researching automatic and fast-switching devices under specific operating modes.

Dual power automatic fast switching

“…Electricity is one of the most important energy sources in human life. It exists in all areas of life and is indispensable [1][2][3] .With the development of society, the dual-channel AC fast-switching power supply is widely used [4][5][6] . Factories, schools, hotels, underground drilling teams and special application environments are equipped with dual-power supplies [7][8][9] .…”
