Abstract

The invention belongs to the technical field of power grid operation and control, in particular to a phase modifier configuration method of an ultrahigh-voltage (UHV) DC sender power grid. The methodspecifically relates to a phase modifier configuration method of a UHV DC sender power grid. The method includes the following steps: acquiring the operation parameters of a UHV DC sender power grid;determining the configuration number of phase modifiers; analyzing the reactive power and voltage sensitivity of the UHV DC sender power grid to obtain a primary set of phase modifier configuration positions; calculating out a phase modifier configuration strategy by using an artificial bee colony algorithm; and obtaining a phase modifier configuration strategy of the UHV DC sender power grid. Theconfiguration of phase modifiers in the UHV DC sender power grid can be realized more effectively, the voltage operation stability of the power grid can be improved, and a technical basis and a practical method are provided for the operation and control of the UHV DC sender power grid. With the increase of UHV AC/DC transmission systems, the development of reactive power optimal allocation strategies is bound to have greater demand and a good commercial development prospect.

Description

technical field [0001] The invention belongs to the technical field of power grid operation and control, and in particular relates to a method for configuring a condenser for an UHV DC sending-end power grid, in particular to a method for configuring a condenser for an UHV DC sending-end system grid. Background technique [0002] my country's primary energy and load are distributed in reverse. In order to meet the urgent needs of clean energy transmission, load center power supply, energy conservation and emission reduction, the State Grid has vigorously developed UHV AC and DC technologies suitable for long-distance and large-capacity transmission. The positioning of UHV AC and DC transmission projects and the long-distance and large-capacity transmission of large-scale energy bases have become the main ways to alleviate the contradiction between China's energy resources and economic layout. At present, my country is in the transition period of UHV power grid development. W...
