Abstract: Aiming at the weak power supply capabilities and low voltage phenomenon occurs during peak loads in agriculture areas in Huanghua Qinhai, based on Newton-Ralph method, this paper implements modeling and simulation on typical 10kV lines and 0.4 kV lines applying MATLAB/Simulink. Simulation calculation results show that low-voltage area should be in 0.4 kV user circuits and could not occur in 10kV grids and the above. Further, through random simulation and trial on user loads and constructing corresponding simulation model, the reasons on low-voltage occurring are found and feasible control schemes are then proposed.
