Abstract
In order to solve the adverse effects caused by multi point distributed power grid on the feeder steady voltage, power quality of power supply and relay protection, a distributed power triangle load distribution model is put forward, and according to the circuit superposition theorem, the voltage distribution calculation method based on this model is proposed. The verification of this model shows that the triangle load distribution model with distributed power is much better than the uniform load distribution model. Under the condition that the the access position is not changed, the output force is determined by the support function of voltage. The more the output force is, the greater the voltage support function is, and the higher the overall voltage level is. When the output force is unchanged, the closer the access position to the end of the line is, the greater the impact on voltage is. In conclusion, this result provides a theoretical basis for voltage regulation analysis.
