This paper presents a novel fault ride-through (FRT) capability with the use of active converters (Vienna rectifier-I and five-level three-phase modular multilevel converter (MMC)) integrated with permanent magnet synchronous generator (PMSG) supplying AC load. The DC-link fault is controlled with the use of fault blocking diode and MMC sub-module (SM) based wind power plant (WPP). A 16 kW, 60 Hz, PMSG and wind turbine (WT) integrated with the machine-side converter (MSC), and grid-side converter (GSC) are utilized as wind farm components, along with direct current (DC) transmission grid. This topology contributes to the stability and reliability of the system by ensuring continuous output power under transient fault conditions. The functional response of the system is presented using power simulator (The PowerSim, Rockville, USA) software to demonstrate the performance of the proposed controller. [ABSTRACT FROM AUTHOR]

In this article, a fault ride-through controller is proposed with the use of proportional-integral compensator and electronic sensors for riding-through alternative current faults in a wind power plant collection grid connected with a permanent magnet synchronous generator. Three parallel-connected wind energy conversion units supplying a direct current (DC) load are simulated and discussed. It is found that the sub-module will directly adjust the transmission of power and protect the generator from overheating, which can occur due to voltage fluctuation. Furthermore, a DC voltage controller is designed to ensure a stable closed-loop system, and the system stability is verified using bode plots. The dynamic response of the system is demonstrated with the use of power simulator (PowerSim, Rockville, USA) software to verify the reliability of the proposed rectifier topology.
