Konutsal Yüklerin Parametre ve Güç Tüketimi Tahmini

Öz

Teknolojinin gelişmesiyle birlikte elektriksel cihazların davranışları da değişmiştir. Bu durum, yük modelinin geliştirilmesini ve cihazların doğru bir şekilde tanımlanmasının gerekli olduğunu açıkça ortaya koymaktadır. Bu çalışma akkor lamba, Işık Yayan Diyot (LED) lamba, Sıvı Kristal Monitör (LCD) ve elektrik süpürgesi gibi konutsal yüklerin yük modelinin geliştirilmesini, polinomsal yük modeli ve üstel yük modeli katsayılarını deneysel olarak belirlenmesini sunmaktadır. Ölçüm parametreleri, kullanımı kolay ve ekonomik olduğu için PZEM-004T modülü kullanılarak Arduino Uno ile Excel’e aktarılıp Matlab’de bu yük modellerinin katsayıları ve gerilim azaltma oranı hesaplanmıştır. Konutsal yüklerin polinomsal ve üstel yük modeli parametreleri en küçük kareler ve iç nokta yöntemi kullanılarak elde edilmiştir. Ayrıca ZIP yük modeli parametreleri kullanılarak üstel yük modeli parametrelerinin elde edilmesi gösterilmiştir. Akkor lamba ve elektrikli süpürge için bulunan katsayılar ile elde edilen ZIP ve üstel yük modeli gerçek yük modeline çok yakın olduğu ölçümler sayesinde görülmüştür. LED lamba için elde edilen ZIP ve üstel yük modeli ise nominal gerilim etrafında gerçek güç değerlerine yakın sonuç vermektedir. Konutsal yüklerin ZIP yük modeli katsayılarına dayalı tahmini güç tüketimi elde edilerek ölçülen gerçek güç tüketimi ile karşılaştırılmıştır.

Parameter and Power Consumption Estimation of Residental Loads

Öz

With the development of technology, the behavior of electrical devices has also changed. This makes it clear that the development of the load model and the correct identification of the devices are necessary. This study presents the development of the load model of residential loads such as incandescent lamp, Light Emitting Diode (LED) lamp, Liquid Crystal Monitor (LCD) and vacuum cleaner, and experimentally determining the coefficients of the polynomial load model and the exponential load model. Since the measurement parameters are easy to use and economical, PZEM-004T module was transferred to Excel with Arduino Uno and the coefficients and voltage reduction ratio of these load models were calculated in Matlab. It has been determined that both load models are suitable for the incandescent lamp and the vacuum cleaner. Estimated power consumption based on polynomial load model coefficients and actual power consumption results are obtained. According to these results, the estimated power in the incandescent lamp and vacuum cleaner is below the actual power; In the LED lamp and LCD monitor, the estimated power was found to be above the actual power.
