摘要
电能计量是电网经济核算的依据,为了更好的对电能表等计量设备的电磁兼容性能中的辐射骚扰性能进行测试,在电波暗室的基础上,利用电波暗室技术搭建辐射骚扰测试系统。为了测试该系统的性能是否满足标准要求,通过电场强度数学模型的建立,确定了造成测试系统不确定度的影响量,通过定量分析电场强度数学模型扩展不确定度大小,从而间接确定了辐射发射测试系统的不确定度的大小,最终结果满足标准要求。从而保证了本辐射发射测试系统的实用性。最终,保障了电能计量的准确性,提高了电力供需双方的经济效益和社会效益。
Energy measurement is the basis for economic calculation grid. In order to test the emission of the radiation of electromagnetic compatibility of the measuring equipment such as watt-hour meter better, the radio wave darkroom is used. Radiated emission test system which uses radio wave darkroom is set up. In order to test whether the uncer-tainty of the system satisfies the requirement of standard, the mathematical model of field intensity is set up,the factors that influences the uncertainty of the testing system are confirmed. It is believed that the radiated emission test system is practical, by calculating the expanded uncertainty of the mathematical model of field intensity, thus indirectly deter-mine the uncertainty of radiation emission test system. It is believed that the uncertainty of final result meets standard requirements. Ultimately, this protected the energy measurement accuracy, improved electricity supply and demand sides of the economic and social benefits.
