Real-Time Monitoring, Analysis and Control of Power Parameters in Residential Houses Using LabVIEW

Abstract

Electrical energy consumed in residential has an important value in total consumption. For this reason, monitoring and control of the electricity consumed in the residential offers a significant potential for energy saving. In this study, the power parameters of the linear and nonlinear loads used in the residential have measured, analyzed and controlled in real time. Thanks to real-time monitoring, analysis and control of power parameters ensure efficient use of energy. For this, power parameters of the loads used have transferred to the computer thanks to the data acquisition card. A visual interface has been created with the software designed in the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) program so that the data transferred to the computer can be monitored and controlled instantly.

IoT-based monitoring, analysis and supervisory control of voltage harmonics in a three-phase system using four singles tuned lowpass filter

“…These harmonics that periodically occur in a facility can cause equipment malfunction, data distortion, transformer and motor insulation failure, overheating of neutral buses, and solid-state component breakdown [12]. Moreover, according to article [11], this harmonic distortion leads to failure of electrical or electronic components, transformer heating, failure of power factor correction capacitors, and losses in power generation and transmission. In Akagi's study, he showed the minimum and maximum values for the Total Harmonic Distortion (THD) in a typical three-phase power system in Japan with a rating of 6.6kV in power distribution system [1].…”

“…For the individual odd harmonic frequency, THD and must not exceed 3%. Harmonics in the power system are reprimanded for the decrease in the quality of power accessible to non-linear loads [11]. To suppress the effects of power system harmonics, harmonic filters are used.…”

“…In the research conducted by Rajkumar [11], NI-DAQ card for USB was used to acquire and capture the voltage and current waveforms. The system essentially requires two channels of analog input-one for the line voltage and one for the line current.…”

“…This research will focus voltage harmonics that power engineers look at the voltage amplitude rather than the current distortion. A small current may have a high THD, but it does not propose a threat to the whole system [6], [11]. The 230 V/60 Hz needs to be stepped down to 1 V/60 Hz as this microcontroller has a voltage limitation of 5 Vpp thus, tapping the system into the line will not be directly implemented.…”
