Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0039] like figure 1 As shown, a method for improving reactive power support capacity includes:

[0040] Step 1, if it is a preset IPFC converter with improved reactive power support capability, and the connected main control line is faulty, obtain the measured active current and the measured reactive current;

[0041] Step 2, obtaining the active current limit value according to the measured active current and the preset first dynamic adjustment rule;

[0042] Step 3, obtain the reactive current limit value according to the measured reactive current and the preset second dynamic adjustment rule;

[0043] Step 4, according to the active current limit value and the reactive current limit value...

Abstract

The invention discloses a method and system for improving reactive power support capability, a storage medium and computing equipment. As for an IPFC converter for improving the reactive power support capability, when a main control line connected with the IPFC converter fails, the dynamic amplitude limiting values of active current and reactive current are obtained according to the actually measured active current and reactive current; and the active current and the reactive current output by outer loop control are subjected to amplitude limiting through the dynamic amplitude limiting values, so that the reactive output of the IPFC converter is improved, and the reactive support potential of the IPFC converter is released.

Description

technical field [0001] The invention relates to a method, a system, a storage medium and a computing device for improving reactive power support capability, and belongs to the technical field of flexible alternating current transmission. Background technique [0002] Inter-line flow controller (IPFC) is a new generation of flexible AC transmission device with extremely powerful power flow control function. It can accurately and flexibly control the power flow of multi-circuit common corridor transmission lines, so as to balance the power flow of each transmission channel and improve the power flow of scarce corridors. Resource transmission efficiency. In addition, IPFC can also use the converters on the remaining lines to continue to control the power flow of the system after the failure of the controlled line through the switching of its own topology, so as to avoid further deterioration of the situation after the failure and have high reliability. . [0003] On the one h...
