Impact of reactive power compensating equipment in a backbone network on active power losses

Abstract

The article discusses impact of reactive power compensation equipment on active power losses in a backbone network. A modeled 500 kv backbone network is compiled and active power losses in this network are calculated. The calculation is conducted before reactive power compensation and after it for two (maximum, minimum) load modes. As a result of the reports, it was found out that, as expected, a reactive power compensating equipment, selected according to the voltage quality criteria in the backbone network regulates operating voltage values ​​of the nodes within the allowable range and reduces active power and energy losses in the network.
