Abstract

Fast-switching and fast-throwing device is installed at different open loop points of power supply in the power grid, which can provide backup power source for neighbouring supply zones and has important practical value of the reliability improvment of power syetem. The amplitudes and phase angles of voltages measured at two adjacent busbars are different because both sides of the loop closing positon power system are powered by different power sources. The most obvious impact of loop closing operation is the system disturbance and impact current. Therefore, the constraint condition of loop closing is analyzed, and the technical scheme for the fast-switching device is determined. The practicality of the fast-switching and fast-throwing technology applied at the loop closing position between neighbouring supply zones is verified based on the transient simulation data from regional power system of Baotou, China.
