Title:
ＥＭＵの並列補助コンバータ用の同期ソフトスタートネットワーキング制御方法
Document Type and Number:
Japanese Patent JP7165815
Kind Code:
B2
Abstract:
A synchronous soft-start networking control strategy for parallel auxiliary converters of EMU, that is, when a first auxiliary converter is connected to the bus, non-first auxiliary converters complete the networking during an amplitude soft-start process of the first auxiliary converter. Specific solution is: fast networking logic, bus fast-tracking logic and PQ droop networking control strategy. Wherein, the fast networking logic comprises recognizing the first auxiliary converter and the non-first auxiliary converter; the bus fast-tracking logic comprises tracking phase, frequency and amplitude; the PQ droop networking control strategy comprises introducing a correction coefficient K. The synchronous soft-start networking control strategy for the parallel auxiliary converters of EMU can realize quickly and reliably automatic networking in an emergency traction mode of EMU, and significantly shorten networking time in a network normal mode of EMU.Therefore, it can ensure that EMU can complete startup loading within a specified time under various working conditions, which provides strong guarantee for stable and reliable operation of EMU.
