Title:
METHOD AND SYSTEM FOR INTERCONNECTED OPERATION CONTROL OF TRUE AND PSEUDO BIPOLAR DIRECT CURRENT CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/179015
Kind Code:
A1
Abstract:
Disclosed are a method and system for interconnected operation control of a true and pseudo bipolar direct current conversion device. In the present invention, any two of a positive direct current conversion device, a negative direct current conversion device, a pseudo bipolar direct current conversion device are controlled to be started in a constant voltage mode, and corresponding inter-bus voltages are clamped so as to make the voltages of two-pole buses constant; and the remaining device is controlled to be started in a constant power mode, and output power is controlled, such that a direct current system operates normally. In this way, the interconnected operation of the true and pseudo bipolar direct current conversion device is achieved.
