SVG控制模式对新能源场站宽频振荡作用机理分析及工程实践(二):分析与抑制工程案例
Mechanism Analysis and Engineering Practice of SVG Control Modes on Broadband Oscilla-tions in Renewable Energy Plants(Part II):Analysis and Suppression Engineering Case
摘要
Abstract
With the large-scale integration of renewable energy into the power grid,broadband oscillation accidents in renewable energy stations have occurred frequently.Existing research has mostly focused on power generation equipment such as wind turbines and photovoltaic inverters,while few studies have addressed the issues of oscillations induced by auxiliary devices such as static var generators(SVG),with a lack of comparative analysis between theory and practical cases.To address this,taking a broadband oscillation event triggered by SVG control mode switching at a photovoltaic station in China in 2024 as the research subject,we conduct studies on oscillation source tracing and suppression.First,the engineering background is outlined,and oscillation frequency analysis is performed based on field recorded waveform data to clarify the actual oscillation characteristics.Next,the experimental platform and impedance measurement device used for oscillation analysis are introduced,along with the system wiring configuration and measurement procedures.Subsequently,combined with frequency-domain analysis and time-domain simulation,the oscillation source is progres-sively identified at the station level and equipment level.Finally,based on the tracing results,control parameters of the oscillation source equipment are optimized,and oscillation suppression is achieved through impedance reshaping,thereby addressing the practical engineering problem.关键词
