Research on Power Outage Scheme for 220 kV Substation Based on Power Flow Simulation Calculation
If the 220 kV substation is planned to be blacked out,it is necessary to carry out power flow simulation calculations in advance,so as to judge whether there are problems such as line overcurrent or substation heavy load in the neighbouring grid,formulate corresponding countermeasures,adjust the operation mode,and arrange for load transferring and supplying.Especially for the weak links in the neighbouring grid,how to reasonably arrange the correct timing of power outage construction becomes the focus of research.Taking 220 kV station A as an example,by analysing the power flow and short-circuit current situation of the peripheral lines during its outage,the outage time is reasonably arranged to ensure the safe and stable operation of the power grid and the reliability of users'power consumption.
