(PDF) Fault-Tolerant Approach For Modular Multilevel Converters Under Submodule Faults

(PDF) Fault-Tolerant Approach For Modular Multilevel Converters Under Submodule Faults The fault tolerant operation is one of the important issues for the mmc. this paper proposed a fault tolerant approach for the mmc under submodule (sm) faults. Aiming at this problem and for better deal with the multiple sm fault conditions, also under the background of the redundant sms equipped with hot reserve scheme and only bypassing the faulty sms when sms malfunction, a novel fault tolerant control strategy is proposed in this paper.

Therefore, this paper proposes a modified submodule circuit for modular multilevel converter that offers an improved dc fault ride through performance with reduced semiconductor losses and enhanced control flexibility compared to that achievable with full bridge submodules. Abstract— this paper proposes a fault tolerant method for the half bridge based modular multilevel converter (mmc). fault tolerance is able to enhance reliability which is one of the crucial issue for the mmc with a large number of switching devices. The modular multilevel converters become more and more popular in high power applications in recent years. the solution to make the mmc operate well under the s. Chapter 5 offers fault tolerant operation under submodule faults. finally, chapter 6 presents the control of mmcs under ac grid faults, and chapter 7 explores the protection under dc short circuit fault of the mmc system.

Chapter 5 offers fault tolerant operation under submodule faults. finally, chapter 6 presents the control of mmcs under ac grid faults, and chapter 7 explores the protection under dc short circuit fault of the mmc system. To strengthen the performances of mmcs under submodule (sm) faults, a fault tolerant strategy based on the nearest level modulation (nlm) is proposed in this paper. Modular multilevel converters (mmcs) are widely used in medium voltage application. it is necessary to design the control strategy under sub modules (sms) failure conditions. Modular multilevel converter (mmc) topology is considered a good candidate for high voltage applications. one of the reasons is that an mmc can quickly generate a higher voltage with an excellent sine wave with the series connection of many power blocks, called sub modules (sms). This paper proposed a fault tolerant approach for the mmc under submodule (sm) faults. the characteristic of the mmc with arms containing different number of healthy sms under faults is analyzed.
