This article focuses on several specific issues with the algorithms of modern static meters to correctly measure active power and to register energy in three phase networks with mixed generation and consumption metered simultaneously. It specifically focuses on the still vague definitions of methods to evaluate positive and negative components of the calculated three phase active power from the measured...
Standard EN 50160 ED. 3 was released in 2011 and despite the fact that this is the third edition of this standard, it still does not limit values for all parameters at all voltage levels. This article examines the various methods of evaluation variables with two levels and then presents some recommendations for amendments undefined parameters vvn network in EN 50160 ED. 3rd.
An artificial neural network (ANN)-based method for the design of virtual power meter, which is able to evaluate the power quantities for the single-phase system, is introduced in this paper. The solution procedure contains two stages. In the first stage, the spectral analysis of voltage and current signals are performed separately with the ANN-based method in the real-time manner. Then, the power...
Modern digital metering technology and advances in power definition theory have made it possible to produce revenue meters that measure the correct quantities even in non-sinusoidal conditions. These developments are reflected in the designs of several metering integrated circuits and in the IEEE 1459-2000 power definitions standard. These advances now need to be included in metering standards and...
Conducted Emission (CE) measurement for AC operated equipment is carried out to quantify the amount of noise/interference generated by Equipment Under Test (EUT) and sent back to power supply input terminal through power cable. The increased use of non linear devices has resulted in increased dasiapower harmonicspsila and thus degradation of power quality. The interference generated by the EUT will...
