Abstract

Provided in the present application are a power conversion device, and a waveform recording method and system for a power conversion device. The method comprises: when a power conversion device is in a grid-connected stage, a communication unit of the power conversion device forwarding to a data processing unit a received data acquisition message sent by an external adjustment device; according to the data acquisition mode indicated by the data acquisition message, the data processing unit acquiring grid-connected operation data of a power conversion unit in the grid-connected stage; on the basis of the acquired grid-connected operation data, generating a feedback message, and sending the feedback message to the communication unit; and the communication unit sending the feedback message to the external adjustment device, such that the external adjustment device monitors the grid-connected state of the power conversion device on the basis of the feedback message. The method involves acquiring the grid-connected operation data of the power conversion unit in a grid-connected working state, thus related technicians can adjust the power conversion unit and analyze the operation conditions thereof on the basis of the data, thereby improving the development and adjustment efficiency of power conversion units.
