Power systems , electrical equipment Duocheng emotional , leading to the large amount of reactive power grid , reducing the quality of power supply . In particular , the low voltage distribution grid, power quality is poor due to the long transmission lines , distribution transformers , making greater line losses . Therefore , to optimize the distribution network reactive power compensation , is of great significance to improve the voltage quality and reduce line losses . In this paper, with the grid load node voltage sensitive choice of reactive power compensation device installation point . And on the basis of research the Reactive Compensation Status and devices compensation characteristics of practical optimization algorithm . 26 - node system and IEEE-30 node system to verify the correctness of the theory .
