直流电能纹波影响试验装置校准
|
摘要
新能源轨道交通、电动汽车充电和光伏等产业的发展带动了直流电能的推广应用,电能计量也由传统的交流电能计量向直流加交流电能计量演变。计量中存在的一个很大问题是直流中的纹波会使传统单纯的直流电能计量方法出现较大误差。GB/T 33708-2017《静止式直流电能表》标准的实施,对直流电能表的检定提出了新的要求,明确了直流纹波影响试验的试验方法和误差要求。目前市场上已经出现了能够进行直流电能纹波影响试验的装置,对校准工作提出了新的挑战。以标准表法为理论依据的核准系统,为直流电能校准提供了参考。
The development of new energy rail transportation,electric vehicle charging and photovoltaic industrieshas led to the popularization and application of DC energy,the energy metering also evolves from traditional AC energy metering to the DC and AC energy metering.A big problem in metering is that the ripple in DC causes a large error in the traditional simple DC energy metering method.The implementation of GB/T 33708-2017 "Static DC energy meter" puts forward new requirements for the verification of DC electric energy meter; and makes clear the method and error limit of the impact test of DC energy ripple.At present,there are some equipment with DC ripple impact test function,new challengefor calibration is put forward.A new method based on standard meter provides a reference for DC power calibration.
