This paper presents a novel interconnecting approach for an offshore wind farm, where pulse width modulated (PWM) current-source converter(CSC) of each wind generator is series connected and dc output is fed by submarine cable to the series connected PWM CSCs on grid side. The total number of series connected PWM CSCs for the onshore grid connections are equal to the number of wind generators installed...
This paper presents a reactive power control scheme for Current Source Converter (CSC) based wind energy system using a Permanent Magnetic Synchronous Generator (PMSG). The novelty of the proposed scheme is to adjust d-axis current of the PMSG to achieve reactive power control for the utility grid. The principle of the control scheme is discussed, and theoretical analysis is provided. The effectiveness...
In a current source converter (CSC) based wind energy system, the dc link current plays an important role in determining the system dynamic performance. This paper proposes two control strategies that can be used to improve the dynamic performance of the dc link current in a CSC wind energy system using permanent magnet synchronous machine (PMSM). State space equations and small-signal models of the...
