虚拟仪器在电能质量测试中的应用

Application of Virtual Instrument in Measuring the Quality of Electric Energy

随着电能在国民经济各部门的广泛应用,用电负荷迅速增加,特别是不对称、冲击性、非线性负荷容量的急剧增长,使得电能质量的问题日益突出,为此提出基于虚拟仪器理论和电气参数测试原理的电气信号测量新算法,并采用LabVIEW软件开发平台对该算法进行了仿真,仿真结果表明了该算法的精确性和可行性。

Along with the rapid load increment and wider application of electric energy in national economy, especially the abrupt growth of unsymmetrical, impact or non-linear load capacity, the quality of the electric energy becomes glaring day by day. Thus the new algorithm for measuring electr/e signals based on virtual instrument theory and measuring principle for electric parameters is proposed. The algorithm is simulated on LabVIEW software developing platform ; the simulation result proves the accuracy and feasibility of this algorithm.
