摘要(Abstract):
为解决变频调速系统谐波测试与分析方法不完善、测试成本高等问题,建立一种涵盖变频器输入、输出侧的谐波分析评价指标体系,包含输入、输出侧谐波电压总畸变率,输入、输出侧谐波电流总畸变率,输入、输出侧三相电压不平衡度,以及输出侧供电谐波电压因数、谐波电流因数、谐波电流允许值9项指标,明确各项指标的计算方法;提出基于LabVIEW软件平台的虚拟仪器谐波分析与测试方法,开发LabVIEW谐波分析程序,与外置数据采集结合,实现谐波测试及信号采集、处理与分析功能,应用数理统计方法分析谐波频率、畸变率等指标对系统中主要设备效率的影响趋势。结果表明:与传统测试仪器Norma5000的结果比较,平均相对误差为0.69%,谐波评价指标体系及虚拟仪器测试方法正确可行,为变频系统谐波防治提供指导。
