基于IEC标准的新型电能质量监测装置
New Power Quality Monitoring Device Based on IEC Standards
In order to develope new generation power quality monitoring device,the paper analyzes some important problems of the IEC power quality measurement standards(IEC61000-4-30、IEC61000-4-7、IEC61000-4-15)firstly,such as data window width,harmonics measurement method,harmonics sub-group,flicker measurement model,etc.Then it presents a harmonics algorithm namely Block FFT Algorithm which met the requirements of the IEC harmonics measurement standards.Based on the analysis and the algorithm a new power quality on-line monitoring device namely PQM09-6 Multi-loop Power Quality On-line Monitoring Device is developed successfully.The testing report furnished by a professional organization show that the PQM09-6 Multi-loop Power Quality On-line Monitoring Device accords with the principle of the IEC standards and has ’A-class consistency’ of power quality measurement.Moreover,the PQM09-6 Monitoring Device can monitor 6 electric loops(a 1oop consists of 6×3 voltage channels and 6×3 current channels).
