Embodiment Construction
[0024] In order to further describe the technical features and effects of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as Figure 1-2 As shown, this embodiment proposes an energy storage and phase regulator control system and method for suppressing DC continuous commutation failure. The so-called coordinated control of energy storage and regulator to suppress DC continuous commutation failure refers to the use of coordinated control of energy storage and regulator to provide reactive power support in the vicinity of the DC converter station after the failure of DC commutation due to a grid fault, reducing the subsequent The probability of commutation failure occurs, avoiding DC blocking due to continuous commutation failure, resulting in large power loss of the grid.
[0026] The energy storage and phase controller coordinated control system for suppressing DC...
