LC filter parameter visualization design method of energy storage converter

Abstract

The invention provides an LC filter parameter visualization design method of an energy storage converter. The LC filter parameter visualization design method comprises the steps of S1, drawing a selection range of inductance parameters; S2, drawing a selection range of capacitance parameters; S3, drawing a selection range of cut-off frequency parameters; S4, designing LC filter parameters in combination with inductance, capacitance and cut-off frequency parameter selection ranges; S5, drawing a selection range of the direct-current side voltage; S6, verifying whether the LC filter parameters meet the design requirements or not, if not, returning to the S1 for redesign, and if yes, executing the step S7, and outputting final LC filter parameter values. Parameter design is carried out in a visual mode, parameter selectable areas and change trends can be visually obtained by drawing selectable areas of inductance, capacitance and cut-off frequency parameters, repeated trial and error areavoided, and multiple design indexes such as system cut-off frequency, reactive power, full-load voltage drop and four-quadrant operation can be met at the same time.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a visual design method of LC filter parameters of an energy storage converter, an electronic device and a readable storage medium. Background technique [0002] Due to the large-scale exploitation and utilization of non-renewable energy, the reserves are reduced, resulting in an increasingly serious energy crisis and environmental pollution. Renewable energy sources such as wind energy and solar energy are green, clean and pollution-free, so they have attracted wide attention from all walks of life. However, wind power generation and photovoltaic power generation are intermittent and unstable, and large-scale grid-connected operation will bring many problems to the stable operation and load allocation of the power grid. [0003] Grid energy storage can break the "fire-and-go" model of traditional power grids, separate power generation and electricity consumption from t...
