Reactive Power Optimize Research Of Yuhang Power Supply Grid

In this paper, the grid for the study of Yuhang, the main cause for excess reactive power reactive power to send down the line loss rate is too high and other issues, according to the SCAD A measured data to simulate a typical operating mode Yuhang grid voltage and reactive power problem exists trend status, Yuhang grid to reproduce the actual operation of the current situation. And the establishment of reactive power capability evaluation system, hierarchical system evaluation Yuhang district reactive power demand and reactive power regulation, determine the need for reactive power compensation reactor area. Accordingly, the establishment of reactor reactive power compensation planning, optimization model, the use of enumeration method to solve the model to study the development of Yuhang reactor reactive power compensation planning, installation of the reactor to determine the required reactive power compensation device location, capacity, number of groups and switching strategies.In this paper, the measured data Yuhang SCADA network based on hierarchical partitioning of the study through the calculation, for the use of reactor reactive power compensation equipment to improve pass rate of force Yuhang Bureau voltage and reactive power management level pass rate and provide a solid technical support.
