Abstract

Renewable energy grid-connected converters are rapidly increasing in single-unit capacity and power generation share. After short-circuit faults occur

renewable energy systems without synchronous power sources rely on converters to actively inject reactive power to support grid voltage. However

the reactive power regulation range of the grid-connected converters during fault ride-through is affected by various factors including equipment electrical stress constraints and fault types. This range varies continuously during current injection

which may cause the converters to go off-grid when the injected current exceeds the safe controllable boundary. This paper takes full-power renewable energy grid-connected converters such as photovoltaic and direct-drive wind turbines as the research objects

and derives the safe controllable boundaries for converters to inject positive and negative sequence reactive currents during fault ride-through. By analyzing the coupling relationship between injected reactive current and the controllable boundaries

an iterative calculation method for the controllable boundaries considering coupling effects is proposed to improve calculation accuracy. On this basis

this paper analyzes the influence law of the electrical limit of the converter device

fault type

grid strength and other factors on the controllable boundaries

which can provide a design basis for the reactive current references of converters during fault ride-through. Finally

the effectiveness and accuracy of the proposed controllable boundary calculation method are verified by the Matlab/Simulink simulation platform.
