Abstract: | Existence of reactive power in the Pingliang power grid can be attributed to the unreasonable distribution of reactive power tides and higher voltage existing in the Huating power network. To find out the causes and to address the problem effectively, the reactive power optimization computation is done according to the four typical modes of the Pingliang power grid, analyses are done for the distribution and compensation of the reactive power in the grid. It is concluded that lowering the system voltage of the 110 kV Huating network be the right solution to solve the reactive power issue. |
