A novel quasi‐hot standby fault‐tolerant control strategy for cascaded H‐bridge rectifier
نویسندگان
چکیده
Cascaded H-bridge rectifier (CHBR) is widely used in high-power fields such as STATCOM and power electric traction transformer (PETT) due to its high efficiency easy expandability. With the high-reliability operation requirements of equipment, fault-tolerance capability has gradually become a research hotspot nowadays. In order improve reliability supply, cascaded should restore soon possible after fault. However, traditional fault-tolerant strategies have great effect on grid side long recovery time. This paper proposed quasi-hot standby control strategy. Compared with strategies, strategy faster speed malfunction, transient process less impact grid. Simulation experiment results show effectiveness good performance

A Novel Hybrid Droop-Isochronous Control Strategy for Microgrid Management
The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...

In this paper, a novel and simple control strategy, based on state feedback method is suggested to control the power injection system (PIS). The considered PIS is composed of, a DC voltage source, a voltage source inverter (VSI) and a L-C-L filter. The DC source includes the battery source with boosted voltage. The battery can be charged with photovoltaic cells. Since, the grid voltage acts as ...

Multiloop Interleaved Control (MIC) is proposed, and it is combined with conventional multiloop controland the interleaved pulsewidth modulation scheme. The averagebehavior of the interleaved three-level switch-mode rectifier(SMR) behaves similar to the conventional boost-type SMR eventhough two capacitor voltages are imbalanced. It implies thatconventional multiloop control can be applied to t...
