technical field [0001] The invention belongs to the technical field of electromagnetic transient simulation of SVG reactive power compensation devices in new energy power generation bases, and relates to a simulation platform and simulation method for SVG control hardware in the loop. Background technique [0002] At present, the fault ride-through control strategy, voltage tolerance and reactive power / voltage control strategy of the power generation unit and reactive power compensation device of the existing new energy cluster transmission system have great constraints on the DC transmission capacity, and the DC transmission power grid is weak and unsupported. Insufficient capacity, DC commutation failure, blocking and other faults are likely to cause a large number of power generation units to be disconnected from the grid. Due to the complex voltage regulation characteristics of wind turbines, photovoltaic power generation units, and dynamic reactive power compensation de...
