摘要
云南风电场SVG(动态无功补偿装置)整体利用率较低,冗余容量较高。SVG配置容量是在工程可行性研究阶段经数值仿真计算得出,运行阶段SVG年出力最大值远低于配置容量,两者存在较大差异性。文章在分析云南风电场SVG运行现状基础上,利用Power Factory/DIg SILENT软件建立风电场无功损耗通用仿真模型,并通过实际数据对比分析验证模型的有效性。利用该仿真模型,文章研究了差异性产生的原因,提出优化措施建议,为云南风电场SVG运行与仿真提供指导和参考。
The utilization rate of SVG （Static Var Generator） in wind power plant of Yunnan is low and the residual capacity is high. The allocated SVG capacity is determined through calculation in feasibility analysis stage while the annual output reactive power is far lower than the allocated SVG capacity, meaning large diflerence between the two. Based on the analysis of current situation of SVG operation in Yunnan wind power plants, this paper establishes general reactive power loss simulation model using PowerFactory/DIgSILENT and verifles the eflectiveness of the model by comparison and analysis with actual operation data. By using the model, this paper deeply analysis the reason of diflerence and proposes recommendation of optimization so as to provide instruction for SVG operation and simulation in Yunnan wind power plant.
