Benefits of technology

This technology helps prevent interruptions or other issues with an electronic system's connection between two controllers when there may be any changes made during operation due to factors like temperature variations over time (T). By adjusting certain parameters such as voltage levels based upon these differences, this technology ensures stable performance even if some components fail at one point along their respective signal paths.

Problems solved by technology

The technical problem addressed in this patented technology relates to interconnecting two types of networks together without causing any issues or failures that could affect their performance. This makes it challenging to achieve more precise and dynamic voltage regulation than current methods like static var compensators (SVC).

Embodiment Construction

[0045] 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.

[0046] Such as figure 1 Shown, a kind of oscillation suppression method, comprises the following steps:

[0047] Step 1, obtaining the frequency difference of the connected main control line in response to the oscillation caused by the failure of the connected main control line;

[0048] Step 2, performing lead-lag control on the frequency difference to obtain active power;

[0049] Step 3: Perform constant power control of the outer loop according to the active power to obtain the active current of the outer loop to suppress oscillation.

[0050] The above method is used in the converter of IPFC, mainly to obtain the frequency difference of the main control line that causes oscillation in th...

Abstract

The invention discloses an oscillation suppression method and system, a readable storage medium and computing equipment, and the method comprises the steps: obtaining a frequency difference of a main control line causing oscillation, carrying out the lead-lag control of the frequency difference, adding the active power obtained through the lead-lag control into outer-loop constant power control, carrying out the oscillation suppression, and achieving the suppression of oscillation caused by the IPFC to the connected main control circuit is realized, so various oscillations caused by faults of different main control circuits can be suppressed through a single IPFC.
