[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...
