The rural power grid in China has such characteristics as weak power grid structure

larger supply radius

obsolete power equipment

smaller wire diameter of low-voltage line

smaller and seasonal variation load demand and the low-voltage issue due to this limits normal power consumption of rural users. Therefore

in this paper

the fixed series compensation technology is taken as study object

its voltage regulation and energy-saving principle are analyzed

the address selection and capacitance determination method for the series compensation are proposed. Finally

the actual line is taken as foundation to set up line simulation model covering the reactive power compensation. The low-voltage control

energy-saving and loss reduction result of series reactive power compensation in rural network is discussed through simulation analysis low-voltage management in rural grid. It is shown by the result that the issue of the low-voltage in the line after compensation is controlled.
