新疆电网220 kV风电汇集站构网型SVG人工三相短路试验分析
Analysis of Artificial Three Phase Short Circuit Test for Grid-forming SVG of 220 kV Wind Turbine Substation in Xinjiang Power Grid
摘要
Abstract
With the significant increase in the proportion of renewable energy and the growing penetration of power electronic devices in generation,transmission,and consumption,high-penetration renewable energy grids face prominent stability challenges due to the lack of traditional synchronous generators and other active voltage sources.This leads to reduced system short-circuit capacity,diminished rotational inertia,and frequent frequency/voltage stability issues.In response,focuses on the research of grid-forming static var generators(SVGs).Based on simulation analysis of grid-forming SVGs,a three-phase artificial short-circuit test was conducted on a grid-forming SVG at a 220 kV wind farm collection station in the Xinjiang power grid.The test systematically validated the grid-forming SVG's capabilities in synchronous voltage support,transient instantaneous response,and 3×overload capacity for 10 seconds.Additionally,factors contributing to discrepancies between calculated and measured values were analyzed.The test achieved its intended objectives,demonstrating that the grid-forming SVG maintains grid-forming characteristics during short-circuit faults and exhibits robust system support capabilities.关键词
