After large-scale industrial power users with voltage levels of 110 kV and above powered by dedicated lines are unable to start production or shut down in a timely manner,the active power of the power user substation is very low. However,the reactive power generated by the outdoor overhead lines of the substation is relatively large,resulting in a low power factor for electricity metering for power users,which has a negative impact on the quality of power supply to the grid.At the same time,under the two part electricity pricing system,power users will generate a large amount of power adjustment fees,Increase electricity cost expenditure.According to the two part electricity pricing rules,adjusting the operation strategy of the main transformer and adjusting the reactive power compensation method of SVG (Static Var Generator)can solve the above problems.
